The peritoneal cavity is a potential space between the parietal peritoneum (the peritoneum that surrounds the abdominal wall) and visceral peritoneum (the peritoneum that surrounds the internal organs).Tank, P. (2013) Grants Dissector 15th ed., ch.4 The abdomen, p.
|
|
The abdominal cavity is lined with a protective membrane termed the peritoneum. The inside wall is covered by the parietal peritoneum. The kidneys are located behind the peritoneum, in the retroperitoneum, outside the abdominal cavity. The viscera are also covered by visceral peritoneum.
|
|
Urogenital peritoneum is a portion of the posterior abdominal peritoneum that is found below the linea terminalis. It includes the broad ligament of uterus.
|
|
Foreign bodies in the peritoneum can include retained surgical instruments after abdominal surgery. Rarely, an intrauterine device can perforate the uterine wall and enter the peritoneum. Foreign bodies in the peritoneum eventually become contained in a foreign body granuloma. In the extremely rare case of retained ectopic pregnancy, this forms a lithopedion.

4 The abdomen, p.99 The tunica vaginalis, the serous membrane covering the male testis, is derived from the vaginal process, an outpouching of the parietal peritoneum. The inner layer, the visceral peritoneum, is wrapped around the visceral organs, located inside the intraperitoneal space for protection. It is thinner than the parietal peritoneum.
|
|
The peritoneum is a mesothelial lining covering the abdominal cavity (parietal peritoneum) and intraperitoneal organs (visceral peritoneum). Peritoneal cavity contains a small amount of fluid, which circulates under the influence of negative pressure generated by the diaphragm, gravity and bowel peristalsis. This natural flow pattern determines the route of spread of disease processes within the peritoneal cavity. Peritoneal carcinomatosis (PC) is defined as intraperitoneal dissemination of any tumor which is not originated from the peritoneum itself.

Primary peritoneal cancer is a cancer of the cells lining the peritoneum.
|
|
The peritoneum divides the cavity into numerous compartments. One of these the lesser sac is located behind the stomach and joins into the greater sac via the foramen of Winslow. Some of the organs are attached to the walls of the abdomen via folds of peritoneum and ligaments, such as the liver and others use broad areas of the peritoneum, such as the pancreas. The peritoneal ligaments are actually dense folds of the peritoneum that are used to connect viscera to viscera or viscera to the walls of the abdomen.
|
|
The peritoneum is one continuous sheet, forming two layers and a potential space between them: the peritoneal cavity. The outer layer, the parietal peritoneum, is attached to the abdominal wall and the pelvic walls.Tank, P. (2013) Grants Dissector 15th ed., ch.

|
These cells are derived from the mesoderm during embryonic development and are closely related to the mesothelium of the peritoneum. The germinal epithelium gives the ovary a dull gray color as compared with the shining smoothness of the peritoneum; and the transition between the mesothelium of the peritoneum and the cuboidal cells which cover the ovary is usually marked by a line around the anterior border of the ovary.
|
|
The term "peritonitis" comes from Greek περιτόναιον peritonaion "peritoneum, abdominal membrane" and -itis "inflammation".
|
|
Carcinosis of the peritoneum may cause pain through inflammation, disordered visceral motility, or pressure of the metastases on nerves. Once a tumor has penetrated or perforated hollow viscera, acute inflammation of the peritoneum appears, inducing severe abdominal pain. Pleural carcinomatosis is normally painless.

|
This fish is also the only Minnesota Notropis species that has a darkly pigmented peritoneum.
|
|
During embryogenesis, the testis descends through the inguinal canal, drawing a diverticulum of peritoneum into the scrotum as it descends. This peritoneal tissue is known as the processus vaginalis. Normally, the communication between the processus vaginalis and the peritoneum is obliterated, and the tunica vaginalis is the tissue that remains overlying the testis and the epididymis. Congenital hydrocele results when the processus vaginalis remains, allowing fluid from the peritoneum to accumulate in the scrotum.
|
|
In patients with peripheral arterial disease, ligation of inferior epigastric vessels may lead to distal ischemia. Finally, the peritoneum is cut laterally. After the surgery, peritoneum is closed with an absorbable suture. The ties placed on the inferior epigastric vessels are inspected to ensure hemostasis.

In the adult, the ventral mesentery is the part of the peritoneum closest to the navel.
|
|
Ectopic decidua most commonly occurs the ovary, cervix and serosal lining of the uterus. It rarely occurs in peritoneum also. In the peritoneum, ectopic decidua is formed due to metaplasia of subserosal stromal cells under the influence of progesterone. It regresses within 4–6 weeks after childbirth.
|
|
In this process they become enveloped in a layer of peritoneum. The growing organs "take their blood vessels with them" from the abdominal wall, and these blood vessels become covered by peritoneum, forming a mesentery. Peritoneal folds develop from the ventral and dorsal mesentery of the embryo.
|
|
Peritoneal mesothelioma is the name given to the cancer that attacks the lining of the abdomen. This type of cancer affects the lining that protects the contents of the abdomen and which also provides a lubricating fluid to enable the organs to move and work properly. The peritoneum is made of two parts, the visceral and parietal peritoneum. The visceral peritoneum covers the internal organs and makes up most of the outer layer of the intestinal tract.
|
|
The peritoneum surrounds the uterus like a flat sheet that folds over its fundus, covering it anteriorly and posteriorly; on the sides of the uterus, this sheet of peritoneum comes in direct contact with itself, forming the double layer of peritoneum known as the broad ligament of the uterus. The part where this peritoneal sheet is folded (i.e. the free edge) has the uterine tubes running between the two layers; this part is known as the mesosalpinx.
|
|
The peritoneum of the anterior pelvic wall covers the superior surface of the bladder, and on either side of this viscus forms a depression, termed the paravesical fossa, which is limited laterally by the fold of peritoneum covering the ductus deferens. The size of this fossa is dependent on the state of distension of the bladder; when the bladder is empty, a variable fold of peritoneum, the plica vesicalis transversa, divides the fossa into two portions.
|
|
Between the visceral and parietal peritoneum is the peritoneal cavity, which is a potential space. It contains serous fluid that allows motion. This motion is apparent of the gastrointestinal tract. The peritoneum, by virtue of its connection to the two (parietal and visceral) portions, gives support to the abdominal organs.
|
|
Congenital adhesions occur between the lateral aspect of the peritoneum overlying the mobile component of the mesosigmoid, and the parietal peritoneum in the left iliac fossa. During lateral to medial approach of mobilizing of the mesosigmoid, these must be divided first before the peritoneum proper can be accessed. Similarly, focal adhesions occur between the undersurface of the greater omentum and the cephalad aspect of the transverse mesocolon. These can be accessed after dividing the peritoneal fold that links the greater omentum and transverse colon.

Mauriciosaurus probably pursued small prey, due to its slender snout and small, pointed teeth. The soft tissue structures interpreted as the peritoneum of Mauriciosaurus would have been richly pigmented by melanocytes. In living squamates which reside in deserts or at high altitudes, pigmentation of the peritoneum protects the body cavity against solar ultraviolet radiation, thereby preventing damage to reproductive organs. As a surface-swimming plesiosaur, Mauriciosaurus would have been frequently exposed to solar radiation, and thus a pigmented peritoneum would have been advantageous particularly during the early stages of its life.
|
|
The perimetrium (or serous coat of uterus) is the outer serosa layer of the uterus, equivalent to peritoneum. It is embrionically derived from visceral peritoneum. The perimetrium consists of superficial mesothelium, and a thin layer of loose connective tissue beneath it. The posterior surface of the uterus is completely covered by the perimetrium, but the anterior surface only partially.

|
Portions of the gut tube and its derives are suspended from the dorsal and ventral body wall by mesenteries, double layers of peritoneum that enclose an organ and connect it to the body wall. Such organs are called intraperitoneal, whereas organs that lie against the posterior body wall and are covered by peritoneum on their anterior surface only are considered retroperitoneal. So, mesenteries are double layers of peritoneum that pass from one organ to another or from an organ to the body wall as a peritoneal ligament. Mesenteries provide pathways for vessels, nerves, and lymphatic structures to and from abdominal viscera.

The back has a smooth shagreen-like texture, while the entirely transparent belly skin has a grainy surface. The forward quarter to half of the parietal (outer) peritoneum is white, while the rest is transparent, allowing to see the frog's interior. The pericardium and the inner peritoneum covering the gastrointestinal tract are white, while the inner peritoneum protecting the brown lobes of the liver is also transparent except for the anterior tip (where some iridophores may be present). The iris is greyish white with a network of thin dark grey lines; in Helena's glass frog it is bright yellow.

Toldt's fascia, is a discrete layer of connective tissue containing lymphatic channels. It is found between the two mesothelial layers that separate the mesocolon from the underlying retroperitoneum. It was first described by the Austrian anatomist Carl Toldt (1840–1920) as a fascial plane formed by the fusion of the visceral peritoneum with the parietal peritoneum. This was later called Toldt's fascia.

Sachatamia have moderate to extensive webbing between third and fourth fingers. The dorsum is lavender in preserved individuals and may have spots. Internal features include green bones (in live specimens), lobed liver that is covered by a transparent hepatic peritoneum, whereas the ventral parietal peritoneum is white in its anterior part and transparent in its poster part. The digestive tract is translucent.

Males also develop small bumps upon reaching sexual maturity. L. fabricii can be distinguished from other snailfishes by its dark peritoneum and by the number of soft rays on its anal fin. Although the dark peritoneum is unique among Arctic snailfish, L. fabricii as presently defined is a complex that comprises several species that all have it (some of these have scientific names that can be resurrected, but others remain undescribed).
|
|
The mouth is shaped into a suction disc and has simple unlobed teeth. The peritoneum of L. fabricii is distinctively dark, visible in both the interior of the mouth and behind the gill covers. When alive, the peritoneum also has some silvery markings, but once dead and preserved these rapidly disappear, making it appear all dark. The pectoral fins are large with the tip reaching the anal fin.
|
|
In normal conditions, the peritoneum appears greyish and glistening; it becomes dull 2–4 hours after the onset of peritonitis, initially with scarce serous or slightly turbid fluid. Later on, the exudate becomes creamy and evidently suppurative; in people who are dehydrated, it also becomes very inspissated. The quantity of accumulated exudate varies widely. It may be spread to the whole peritoneum, or be walled off by the omentum and viscera.
|
|
The osmotic activity of icodextrin keeps the solution inside the peritoneum for three to four days, separating tissues and thus reducing adhesion between them when fibrin is formed after a surgery. In other words, the tissues are kept from gluing together. Peritoneal dialysis When used for peritoneal dialysis, the icodextrin solution absorbs waste products from the blood, and is removed from the peritoneum after a few hours together with the waste.

|
A Cargile membrane is a sterile membrane made from the peritoneum of the ox. It is used in abdominal surgery to interpose between raw surfaces and thus prevent the formation of adhesions. It was also used to envelop freshly sutured nerves or tendons, and to protect wounds. It was designed primarily to cover surfaces over which peritoneum has been removed, especially where a sterile membrane would lessen the formation of adhesion.

The diagnostic characters of Espadarana include conspicuous humeral spines present in adult males, as hinted in their name. There is moderate webbing between third and fourth fingers. The dorsum is lavender in preserved individuals and may have spots. Internal features include green bones (in live specimens), lobed liver covered by a transparent hepatic peritoneum, whereas the ventral parietal peritoneum is white in its anterior part and transparent in its poster part.

|
The peritoneum develops ultimately from the mesoderm of the trilaminar embryo. As the mesoderm differentiates, one region known as the lateral plate mesoderm splits to form two layers separated by an intraembryonic coelom. These two layers develop later into the visceral and parietal layers found in all serous cavities, including the peritoneum. As an embryo develops, the various abdominal organs grow into the abdominal cavity from structures in the abdominal wall.

Distally, this close contact remains in the area lateral to the epigastrics. Medially, however, the peritoneum reflects on the roof of the bladder and runs sharply dorsally, away from the deep layer of transversalis fascia. The separation of transversalis fascia and peritoneum contains loose fatty tissue allowing for the filling of the bladder. This space is called the retropubic space of Retzius (from the Clinic of Digestive Surgery, University Hospital St-Pierre, Brussels).
|
|
The femoral ring is closed by a somewhat condensed portion of the extraperitoneal fatty tissue, named the septum femorale (crural septum), the abdominal surface of which supports a small lymph gland and is covered by the parietal peritoneum. The septum femorale is pierced by numerous lymphatic vessels passing from the deep inguinal to the external iliac lymph glands, and the parietal peritoneum immediately above it presents a slight depression named the femoral fossa.

The outer surface of the body wall consists of a simple columnar epithelium covered by a thin cuticle. Underneath this, in order, are a thin layer of connective tissue, a layer of circular muscle, a layer of longitudinal muscle, and a peritoneum surrounding the body cavity. Additional oblique muscles move the parapodia. In most species the body cavity is divided into separate compartments by sheets of peritoneum between each segment, but in some species it's more continuous.

The anterior superior pancreaticoduodenal artery travels in front of the neck of the pancreas. The body is the largest part of the pancreas, and mostly lies behind the stomach, tapering along its length. The peritoneum sits on top of the body of the pancreas, and the transverse colon in front of the peritoneum. Behind the pancreas are several blood vessels, including the aorta, the splenic vein, and the left renal vein, as well as the beginning of the superior mesenteric artery.

The gubernaculum grows into a thick cord. It ends below at the abdominal inguinal ring in a tube of peritoneum, the vaginal process, which protrudes itself down the inguinal canal. By the fifth month the lower part of the gubernaculum still is a thick cord, while the upper part has disappeared. The lower part now consists of a central core of smooth muscle fibers, surrounded by a firm layer of striated muscle elements, connected, behind the peritoneum, with the abdominal wall.

Pathologic explanation: This maneuver elicits tenderness in the right lower abdomen, because contents of the left lower abdomen are shifted upon application of pressure, further irritating the inflamed peritoneum. A Rovsing's sign is elicited by pushing on the abdomen far away from the appendix in the left lower quadrant. The appendix, in a large majority of people, is located in the right lower quadrant. While this maneuver stretches the entire peritoneal lining, it only causes pain in any location where the peritoneum is irritating the muscle.

The vaginal cuff is the upper portion of the vagina that opens up into the peritoneum and is sutured shut after the removal of the cervix and uterus during a hysterectomy. The vaginal cuff is created by suturing together the edges of the surgical site where the cervix was attached to the vagina. This is accomplished by bringing the edges of the vagina together and suturing them together and to the uterosacral ligaments to prevent prolapse. The peritoneum is also sewn into the newly created vaginal cuff.

In human anatomy, the greater sac, also known as the general cavity (of the abdomen) or peritoneum of the peritoneal cavity proper, is the cavity in the abdomen that is inside the peritoneum but outside the lesser sac. A description of the greater sac in three dimensions. It is connected with the lesser sac via the omental foramen, also known as the foramen of Winslow or epiploic foramen, which is anteriorly bounded by the portal triad – portal vein, hepatic artery, and common bile duct.

Paul of Aegina was on the forefront of surgery. He describes the operation to fix a hernia writing, "After making the incision to the extent of three fingers' breadth transversely across the tumor to the groin, and removing the membranes and fat, and the peritoneum being exposed in the middle where it is raised up to a point, let the knob of the probe be applied by which the intestines will be pressed deep down. The prominence, then, of the peritoneum, formed on each side of the knob of the probe, are to be joined together by sutures, and then we extract the probe, neither cutting the peritoneum nor removing the testicle, nor anything else, but curing it with applications used for fresh wounds." Other types of surgery occurred during this time and were described in Paul of Aegina's work, Epitome of Medicine.

In normal circumstances, the parietal mesoderm will form the parietal layer of serous membranes lining the outside (walls) of the peritoneal, pleural, and pericardial cavities. The visceral layer will form the visceral layer of the serous membranes covering the lungs, heart, and abdominal organs. These layers are continuous at the root of each organ as the organs lie in their respective cavities. The peritoneum, a serum membrane that forms the lining of the abdominal cavity, forms in the gut layers and in places mesenteries extend from the gut as double layers of peritoneum.
|
|
The main manifestations of peritonitis are acute abdominal pain, abdominal tenderness, abdominal guarding, rigidity, which are exacerbated by moving the peritoneum, e.g., coughing (forced cough may be used as a test), flexing one's hips, or eliciting the Blumberg sign (meaning that pressing a hand on the abdomen elicits less pain than releasing the hand abruptly, which will aggravate the pain, as the peritoneum snaps back into place). Rigidity is highly specific for diagnosing peritonitis (specificity: 76-100%). The presence of these signs in a person is sometimes referred to as peritonism.
|
|
Implantation sites can be anywhere in the abdomen but can include the peritoneum outside of the uterus, the rectouterine pouch (culdesac of Douglas), omentum, bowel and its mesentery, mesosalpinx, and the peritoneum of the pelvic wall and the abdominal wall. The growing placenta may be attached to several organs including tube and ovary. Rare other sites have been the liver and spleen, giving rise to a hepatic pregnancy or splenic pregnancy, respectively. Even an early diaphragmatic pregnancy has been described in a patient where an embryo began growing on the underside of the diaphragm.
|
|
Specific localization of tenderness to McBurney's point indicates that inflammation is no longer limited to the lumen of the bowel (which localizes pain poorly), and is irritating the lining of the peritoneum at the place where the peritoneum comes into contact with the appendix. Tenderness at McBurney's point suggests the evolution of acute appendicitis to a later stage, and thus, the increased likelihood of rupture. Other abdominal processes can also sometimes cause tenderness at McBurney's point. Thus, this sign is highly useful but neither necessary nor sufficient to make a diagnosis of acute appendicitis.
|
|
In normal circumstances, the parietal mesoderm will form the parietal layer of serous membranes lining the outside (walls) of the peritoneal, pleural, and pericardial cavities. The visceral layer will form the visceral layer of the serous membranes covering the lungs, heart, and abdominal organs. These layers are continuous at the root of each organ as the organs lie in their respective cavities. The peritoneum, a serum membrane that forms the lining of the abdominal cavity, forms in the gut layers and in places mesenteries extend from the gut as double layers of peritoneum.

Toldt was professor of anatomy in Prague and Vienna; he published his account of the human mesentery in 1879. Toldt identified a fascial plane between the mesocolon and the underlying retroperitoneum, formed by the fusion of the visceral peritoneum of the mesocolon with the parietal peritoneum of the retroperitoneum; this later became known as Toldt's fascia. In 1942, anatomist Edward Congdon also demonstrated that the right and left mesocolons persisted into adulthood and remained separate from the retroperitoneum—extraretroperitoneal. Radiologist Wylie J. Dodds described this concept in 1986.

A blood vessel starts from the peritoneum (the membrane that loosely encloses the stomach), with blind capillaries supplying the stomach. The blood vessel leads up the middle of the body to a circular vessel at the base of the lophophore, and from there a single blind vessel runs up each tentacle. A pair of blood vessels near the body wall lead downward from the lophophore ring, and in most species these are combined into one a little below the lophophore ring. The downward vessel(s) leads back to the peritoneum, and also to blind branches throughout the body.

On the diaphragmatic surface, apart from a triangular bare area where it connects to the diaphragm, the liver is covered by a thin, double-layered membrane, the peritoneum, that helps to reduce friction against other organs. This surface covers the convex shape of the two lobes where it accommodates the shape of the diaphragm. The peritoneum folds back on itself to form the falciform ligament and the right and left triangular ligaments. These peritoneal ligaments are not related to the anatomic ligaments in joints, and the right and left triangular ligaments have no known functional importance, though they serve as surface landmarks.

Intrauterine transfusion (IUT) was introduced in 1963 by A.W. Liley. Early IUTs involved transfusion into the fetal peritoneum (abdomen). Almost 20 years later, the procedure was improved to a transfusion into the umbilical vein, which allowed for better absorption of red blood cells.

Peritoneum can be involved by direct invasion, lymphatic paths, intraperitoneal seeding or hematogenous spread. Direct invasion can be contiguous or non-contiguous. Contiguous peritoneal involvement occurs from the involved organ periphery directly. Non- contiguous direct spread directed by peritoneal reflections, ligaments and lymphatic channels.

The urine arrives in the pleural space either retroperitoneally (under the peritoneum) under the posterior diaphragm, or via the retro peritoneal lymphatics. It remains a rare, possibly under-diagnosed, differential in the case of transitive pleural effusion. Respiratory symptoms are usually mild. Handa et al.

The convex diaphragmatic surface of the liver (anterior, superior and a little posterior) is connected to the concavity of the inferior surface of the diaphragm by reflections of peritoneum. The coronary ligament is the largest of these, having an anterior (frontal) and posterior (back) layers. The diaphragmatic surface of the liver that is in direct contact with the diaphragm (just beyond the peritoneal reflections) has no peritoneal covering, and is termed the bare area of the liver. The anterior layer of the coronary ligament is formed by the reflection of the peritoneum from the upper margin of the bare area of the liver to the under surface of the diaphragm.

The transverse colon is the part of the colon from the hepatic flexure, also known as the right colic, (the turn of the colon by the liver) to the splenic flexure also known as the left colic, (the turn of the colon by the spleen). The transverse colon hangs off the stomach, attached to it by a large fold of peritoneum called the greater omentum. On the posterior side, the transverse colon is connected to the posterior abdominal wall by a mesentery known as the transverse mesocolon. The transverse colon is encased in peritoneum, and is therefore mobile (unlike the parts of the colon immediately before and after it).

At an early period of fetal life the testes are placed at the back part of abdominal cavity, behind the peritoneum, and each is attached by a peritoneal fold, the mesorchium, to the mesonephros. From the front of the mesonephros a fold of peritoneum termed the inguinal fold grows forward to meet and fuse with a peritoneal fold, the inguinal crest, which grows backward from the antero-lateral abdominal wall. The testis thus acquires an indirect connection with the anterior abdominal wall. At the same time, a portion of the peritoneal cavity lateral to these fused folds is marked off as the future vaginal process.

The peritoneum is the serous membrane forming the lining of the abdominal cavity or coelom in amniotes and some invertebrates, such as annelids. It covers most of the intra-abdominal (or coelomic) organs, and is composed of a layer of mesothelium supported by a thin layer of connective tissue. This peritoneal lining of the cavity supports many of the abdominal organs and serves as a conduit for their blood vessels, lymphatic vessels, and nerves. The abdominal cavity (the space bounded by the vertebrae, abdominal muscles, diaphragm, and pelvic floor) is different from the intraperitoneal space (located within the abdominal cavity but wrapped in peritoneum).

The retroinguinal space (or Bogros' space) is the extraperitoneal space situated deep to the inguinal ligament. It's limited by the fascia transversalis anteriorly, the peritoneum posteriorly and the iliac fascia laterally. This preperitoneal space communicates with prevesical space of Retzius. It is divided into two compartments.

In peritoneal dialysis, wastes and water are removed from the blood inside the body using the peritoneum as a natural semipermeable membrane. Wastes and excess water move from the blood, across the peritoneal membrane and into a special dialysis solution, called dialysate, in the abdominal cavity.
|
|
Mesothelial hyperplasia is a hyperplasia of mesothelial cells in serous membranes (pleura, pericardium, peritoneum). Mesothelial hyperplasia is usually an incidental finding during peritoneal examination during laparotomy or laparoscopy. Grossly, mesothelial hyperplasia is characterized by the presence of small white nodules or flat plaques on the serous surface.
|
|
The dorsal and anal fins have very faint markings. A narrow dark line marks the base of the caudal fin. The peritoneum, which is a membrane lining the fish’s body, is white with large pigment cells called melanophores. Much of the internal anatomy of Gobioclinus gobio is unknown.

The first were adults of Ophidiascaris sp. (Nemaotoda) in the stomach. Also Cystacaths of Oligatanthorynchus spira (Acanthocephala) were in the peritoneum. The prevalence found in the four different regions, northern and southern coastal Atlantic forest and northern and southern inland Atlantic forest, were observed in Pizatto's and Marques' study.

His name is lent to "Jarjavay's ligament", which is a fold of peritoneum that is also known as a sacrouterine fold,Mondofacto Dictionary sacrouterine fold and "Jarjavay's muscle", which is a structure arising from the ramus of the ischium and inserted into the constrictor muscle of the vagina.
|
|
Computed tomography (CT) imaging may show evidence of colitis, though the sensitivity is relatively low (50%). Free air in the peritoneum indicates bowel perforation. Abdominal imaging may be necessary to rule out toxic megacolon or perforation. Though rare, gastrointestinal metastases (rare) should be considered as a cause of symptoms.
|
|
As the tumor is often enmeshed with the adjacent ovary, it may be the pathologist and not the surgeon who determines that the lesion is indeed tubal in origin. Secondary tubal cancer usually originates from cancer of the ovaries, the endometrium, the GI tract, the peritoneum, and the breast.
|
|
Unconditioned medical-grade CO2 has virtually no moisture and enters the abdomen at room temperature (19 to 21 °C). The condition of the gas is dry and cold compared to that of the natural physiological state of the peritoneum which is immersed in fluid at body temperature (37 °C). Experimental and clinical investigations have demonstrated that insufflation with unconditioned CO2 causes evaporation of the fluid and drying of the peritoneum, resulting in inflammation and damage to its cells. Clinically, peritoneal injury caused by drying has been linked to post-operative pain, evaporative cooling resulting in a decrease in core temperature and increased risk of intra-operative hypothermia, as well as adhesion formation.
|
|
Some burrowing sand dollars have an elongated papilla that enables the liberation of gametes above the surface of the sediment. The gonads are lined with muscles underneath the peritoneum, and these allow the animal to squeeze its gametes through the duct and into the surrounding sea water, where fertilization takes place.
|
|
The urachus is a fibrous remnant of the allantois, a canal that drains the urinary bladder of the fetus that joins and runs within the umbilical cord.Larsen, "Human Embryology," 3rd ed., pg. 258 The fibrous remnant lies in the space of Retzius, between the transverse fascia anteriorly and the peritoneum posteriorly.
|
|
Its body is silver, somewhat darker dorsally; its colour is less bright than in Squalius valentinus. Its scales have a large black spot on their bases and several small black spots on their distal borders. Its peritoneum is also silver, with some small black spots. Its scales are not deciduous.
|
|
At its commencement the greater curvature is covered by peritoneum continuous with that covering the front of the organ. The left part of the curvature gives attachment to the gastrolienal ligament, while to its anterior portion are attached the two layers of the greater omentum, separated from each other by the gastroepiploic vessels.
|
|
The postero-superior surface of the stomach is covered by peritoneum, except over a small area close to the cardiac orifice; this area is limited by the lines of attachment of the gastrophrenic ligament, and lies in apposition with the diaphragm, and frequently with the upper portion of the left suprarenal gland.
|
|
Liparis fabricii, commonly known as the gelatinous seasnail or gelatinous snailfish, is a benthopelagic species of snailfish from the Arctic Ocean. It has a tadpole-like body with a maximum length of about . It is brown to black in coloration with a distinctive dark peritoneum. It preys on small crustaceans and marine worms.
|
|
Peritonitis is inflammation of the peritoneum, the lining of the inner wall of the abdomen and cover of the abdominal organs. Symptoms may include severe pain, swelling of the abdomen, fever, or weight loss. One part or the entire abdomen may be tender. Complications may include shock and acute respiratory distress syndrome.

|
Gastrochisis in ultrasound: defect is right to midline In the developed world, around 90% of cases are identified during normal ultrasound screens, usually in the second trimester. Distinguished from other ventral body wall defects such as omphalocele, there is no overlying sac or peritoneum, and the defect is usually much smaller in gastroschisis.
|
|
However, during the breeding season, this area becomes brilliant red on the males. The females likewise exhibit a colorful, green ventral stripe. Helpful identifying characteristics are its long coiling intestines and the black peritoneum (lining of the body cavity). Its lateral line is incomplete and consists of 70 to 90 lateral line scales.
|
|
Hyalinobatrachium pellucidum, also known as the Rio Azuela glass frog, is a species of frog in the family Centrolenidae. It is found in lower montane rainforests on the Amazonian Andean slopes in Ecuador and Peru. The specific name pellucidum is Latin for "transparent" and refers to the transparent parietal peritoneum of this species.
|
|
The abdominal cavity is continuous with, and above, the pelvic cavity. It is attached to the thoracic cavity by the diaphragm. Structures such as the aorta, inferior vena cava and esophagus pass through the diaphragm. Both the abdominal and pelvic cavities are lined by a serous membrane known as the parietal peritoneum.
|
|
First symptoms may be subtle such as mild pain, flank tenderness, hematuria. Depending on blood loss, symptoms of hypovolemic shock may develop. Hematoma is usually contained in the retroperitoneum, allowing for a period of hemodynamic stability. Sometimes massive acute hemorrhage is seen when a hematoma ruptures Gerota's fascia and extends into the peritoneum.
|
|
The falciform ligament stretches obliquely from the front to the back of the abdomen, with one surface in contact with the peritoneum behind the right rectus abdominis muscle and the diaphragm, and the other in contact with the left lobe of the liver. The ligament stretches from the underside of the diaphragm to the posterior surface of the sheath of the right rectus abdominis muscle, as low down as the umbilicus; by its right margin it extends from the notch on the anterior margin of the liver, as far back as the posterior surface. It is composed of two layers of peritoneum closely united together. Its base or free edge contains, between its layers, the round ligament and the paraumbilical veins.
|
|
The omentum are specialized folds of peritoneum that enclose nerves, blood vessels, lymph channels, fatty tissue, and connective tissue. There are two omenta. First, is the greater omentum that hangs off of the transverse colon and greater curvature of the stomach. The other is the lesser omentum that extends between the stomach and the liver.
|
|
Icodextrin is not significantly metabolised inside the peritoneum. Instead, it is absorbed slowly (40% after 12 hours) into the bloodstream via the lymph vessels. There it is broken down into oligosaccharides by the enzyme alpha-amylase. In patients with intact kidney function, both icodextrin and its fragments are excreted via the kidney by glomerular filtration.
|
|
An appendix with some early inflammation may give a non-specific irritation somewhere near the umbilicus (belly button). Should the inflammation become severe, it may actually irritate the inner lining of the abdominal cavity called the peritoneum. This thin layer of tissue lies deep to the abdominal wall muscles. Now the pain has become "localized".
|
|
In vertebrates, a mesentery is a membrane consisting of a double fold of peritoneum that encloses the intestines and their associated organs and connect them with the dorsal wall of the abdominal cavity. In invertebrates, a mesentery is a support or partition in a body cavity serving a similar function to the mesenteries of vertebrates.
|
|
Tunneling should be applied if a distal infiltration of the adjacent nerve root is preferred. For thoracic and abdominal surgeries, the surgeon will place the catheter superior to the respective fascias. For thoracic surgeries, the catheter goes superior to the pleura. For all type of abdominal surgeries the catheter should be close to the peritoneum.

Charles D. Surh was a leading scientist in the field of immunology. He was a professor at both The Scripps Research Institute and Pohang University of Science and Technology (POSTECH), director of the Academy of Immunology and Microbiology in Pohang, and associate editor of the journal Pleura and Peritoneum. He died from cancer in 2017.

The trophosome can be differentiated between anterior and a posterior area due to incremental changes in host tissue organization, the amount of bacteriocytes, the size and shape of symbionts. The trophosome consisted anteriorly of a small number of bacteriocytes and extensive mesenchyma, while the posterior of trophosome subsequently consisted of a large population of bacteriocytes and a peripheral peritoneum.

Life expectancy is 5–10 years for those on dialysis; some live up to 30 years. Dialysis can occur via the blood (through a catheter or arteriovenous fistula), or through the peritoneum (peritoneal dialysis) Dialysis is typically administered three times a week for several hours at free-standing dialysis centers, allowing recipients to lead an otherwise essentially normal life.
|
|
The phrenosplenic ligament (lienophrenic ligament or phrenicolienal ligament) is a double fold of peritoneum that connects the thoracic diaphragm and spleen. The phrenicosplenic ligament is part of the greater omentum. Distinctions between the phrenicosplenic ligament and adjacent ligaments, such as the gastrophrenic, gastrosplenic and splenorenal ligaments, which are all part of the same mesenteric sheet, are often nebulous.

Papillary serous cystadenocarcinomas are the most common form of malignant ovarian cancer making up 26 percent of ovarian tumours in women aged over 20 in the United States. As with most ovarian tumours, due to the lack of early signs of disease these tumours can be large when discovered and have often metastasized, often by spreading along the peritoneum.
|
|
The scarring may eventually become so severe that the lungs can no longer function. The latency period (meaning the time it takes for the disease to develop) is often 10–20 years. #Mesothelioma - A cancer of the mesothelial lining of the lungs and the chest cavity, the peritoneum (abdominal cavity) or the pericardium (a sac surrounding the heart).

|
Muscular defense is a reflex of the abdominal muscles to contract upon mechanical force to the abdomen, and serves as protection. It is a visceromotor reflex, since the parietal peritoneum and viscera are involved in generating the reflex.A. V. Livshits. The receptor field of reflex contraction of the muscles of the anterior abdominal wall in man.

|
When viewed under the microscope, the Fallopian tube has four to five layers (depending on the classification system used). From outer to inner these are the serosa, subserosa, muscularis, submucosa and innermost mucosa with lamina propria and epithelium. The serosa is derived from the visceral peritoneum. The subserosa is composed of loose adventitious tissue, blood vessels, lymphatics.
|
|
Colic can be divided broadly into several categories: # excessive gas accumulation in the intestine (gas colic) # simple obstruction # strangulating obstruction # non-strangulating infarction # inflammation of the gastrointestinal tract (enteritis, colitis) or the peritoneum (peritonitis) # ulceration of the gastrointestinal mucosa These categories can be further differentiated based on location of the lesion and underlying cause (See Types of colic).

The long dorsal and anal fins contain 97–116 and 76–96 rays respectively. The pelvic fins and caudal fin are small and contain 2 and 8 rays respectively. The coloration is yellowish; the branchial cavity is black and the peritoneum dark brown. The skeleton is well- ossified, consistent with a benthic lifestyle; there are 18–21 precaudal vertebrae.
|
|
Papulae (sing. papula; also occasionally papulla, papullae), also known as dermal branchiae or skin gills, are projections of the coelom of Asteroidea that serve in respiration and waste removal. Papulae are soft, covered externally with the epidermis, and lined internally with peritoneum. They extend through the mesodermal ossicles and are protected from microscopic larvae by pedicellariae.

Laparoscopic image of endometriotic lesions at the peritoneum of the pelvic wall While the exact cause of endometriosis remains unknown, many theories have been presented to better understand and explain its development. These concepts do not necessarily exclude each other. The pathophysiology of endometriosis is likely to be multifactorial and to involve an interplay between several factors.
|
|
Meconium peritonitis refers to rupture of the bowel prior to birth, resulting in fetal stool (meconium) escaping into the surrounding space (peritoneum) leading to inflammation (peritonitis). Despite the bowel rupture, many infants born after meconium peritonitis in utero have normal bowels and have no further issues. Infants with cystic fibrosis are at increased risk for meconium peritonitis.
|
|
Spontaneous bacterial peritonitis (SBP) is the development of a bacterial infection in the peritoneum, despite the absence of an obvious source for the infection. It is specifically an infection of the ascitic fluid – an increased volume of peritoneal fluid. Ascites is most commonly a complication of cirrhosis of the liver. It can also occur in patients with nephrotic syndrome.
|
|
The first appearance of the gonad is essentially the same in the two sexes, and consists in a thickening of the mesothelial layer of the peritoneum. The thick plate of epithelium extends deeply, pushing before it the mesoderm and forming a distinct projection. This is termed the gonadal ridge. The gonadal ridge, in turn, develops into a gonad.
|
|
Peritonitis is the inflammation of the peritoneum. It is more commonly associated to infection from a punctured organ of the abdominal cavity. It can also be provoked by the presence of fluids that produce chemical irritation, such as gastric acid or pancreatic juice. Peritonitis causes fever, tenderness, and pain in the abdominal area, which can be localized or diffuse.
|
|
Peritoneal carcinomatosis (PC) is intraperitoneal dissemination (carcinosis) of any form of cancer that does not originate from the peritoneum itself. PC is most commonly seen in abdominopelvic malignancies. Computed tomography (CT) is particularly important for detailed preoperative assessment and evaluation of the radiological Peritoneal Cancer Index (PCI). The imaging findings vary from simple ascites to multifocal discrete nodules and infiltrative peritoneal masses.
|
|
The internal surface of the ilium showing where the muscles supporting the vagina insert and terminate The vagina is attached to the pelvic walls by endopelvic fascia. The peritoneum is the external layer of skin that covers the fascia. This tissue provides additional support to the pelvic floor. The endopelvic fascia is one continuous sheet of tissue and varies in thickness.
|
|
Mesenteries are folds of peritoneum that are attached to the walls of the abdomen and enclose viscera completely. They are supplied with plentiful amounts of blood. The three most important mesenteries are mesentery for the small intestine, the transverse mesocolon, which attaches the back portion of the colon to the abdominal wall, and the sigmoid mesocolon which enfolds the sigmoid colon.

Raffles Bulletin of Zoology 62 688–95. They are among the smallest members of the family, reaching a maximum standard length of depending on the exact species involved. They have no scales and are transparent, revealing the silvery sheen of the peritoneum lining the abdominal cavity. They are sexually dimorphic, with males bearing longer fins and brighter colors than females.
|
|
Acute abdomen is occasionally used synonymously with peritonitis. While this is not entirely incorrect, peritonitis is the more specific term, referring to inflammation of the peritoneum. It manifests on physical examination as rebound tenderness, or pain upon removal of pressure more than on application of pressure to the abdomen. Peritonitis may result from several of the above diseases, notably appendicitis and pancreatitis.
|
|
The drug is used for the treatment of malignant ascites in people with EpCAM-positive cancer if a standard therapy is not available. Ascites is an accumulation of fluid in the peritoneal cavity. The usual treatment of malignant ascites is to puncture the peritoneum to let the accumulated fluid drain out. After the puncture, catumaxomab is given as an intraperitoneal infusion.
|
|
PID can cause scarring inside the reproductive system, which can later cause serious complications, including chronic pelvic pain, infertility, ectopic pregnancy (the leading cause of pregnancy-related deaths in adult females), and other complications of pregnancy. Occasionally, the infection can spread to the peritoneum causing inflammation and the formation of scar tissue on the external surface of the liver (Fitz-Hugh–Curtis syndrome).
|
|
Appendicitis is a condition characterized by inflammation of the appendix. Pain often begins in the center of the abdomen, corresponding to the appendix's development as part of the embryonic midgut. This pain is typically a dull, poorly localized, visceral pain. As the inflammation progresses, the pain begins to localize more clearly to the right lower quadrant, as the peritoneum becomes inflamed.
|
|
Lesions vary in size. Some within the pelvis walls may not be visible, as normal-appearing peritoneum of infertile women reveals endometriosis on biopsy in 6–13% of cases. Early endometriosis typically occurs on the surfaces of organs in the pelvic and intra-abdominal areas. Health care providers may call areas of endometriosis by different names, such as implants, lesions, or nodules.
|
|
The lungs are within the ribcage, and extend to the back of the ribcage making it possible for them to be listened into through the back. The kidneys are situated beneath the muscles in the area below the end of the ribcage, loosely connected to the peritoneum. A strike to the lower back can damage the kidneys of the person being hit.
|
|
Zooids within a colony can communicate via pores in their interconnecting walls, through which coelomic fluid can be exchanged. The internal, living portion of the zooid is known as the polypide, whose walls are formed by the outer epidermis and inner peritoneum. The lophophore, a ring of ciliated tentacles, protrudes from the polypide to feed.De Burgh, M.E. and P.V. Fankboner (1978).

Ainsworth's salamander is a very attenuated Plethodon with short limbs. It has 16 costal grooves, counting a Y-shaped groove in the groin as two grooves, and four to six costal folds between adpressed limbs. Its peritoneum is not distinctively pigmented. It has 40 premaxillary/maxillary teeth, and palatine teeth in a large median patch, 12 teeth wide and 18 teeth long.
|
|
The falciform ligament is a ligament that attaches the liver to the front body wall, and separates the liver into the left medial lobe and right lateral lobe. The falciform ligament, , is a broad and thin fold of peritoneum, its base being directed downward and backward and its apex upward and forward. The falciform ligament droops down from the hilum of the liver.
|
|
The sigmoid colon is completely surrounded by peritoneum (and thus is not retroperitoneal), which forms a mesentery (sigmoid mesocolon), which diminishes in length from the center toward the ends of the loop, where it disappears, so that the loop is fixed at its junctions with the iliac colon and rectum, but enjoys a considerable range of movement in its central portion.
|
|
The Stoppa procedure is a tension-free type of hernia repair. It is performed by wrapping the lower part of the parietal peritoneum with prosthetic mesh and placing it at a preperitoneal level over Fruchaud's myopectineal orifice. It was first described in 1975 by Rene Stoppa. This operation is also known as "giant prosthetic reinforcement of the visceral sac" (GPRVS).
|
|
Small tumor nests may be camouflaged amongst the muscle or in periappendiceal fat; cytokeratin preparations best demonstrate the tumor cells; mucin stains are also helpful in identifying them. They behave in a more aggressive manner than do classical appendiceal carcinoids. Spread is usually to regional lymph nodes, peritoneum, and particularly the ovary. They do not produce sufficient hormonal substances to cause the carcinoid or other endocrine syndromes.
|
|
In these sections of the gut there is clear boundary between the gut and the surrounding tissue. These parts of the tract have a mesentery. Regions of the gastrointestinal tract behind the peritoneum (called retroperitoneal) are covered with adventitia. They blend into the surrounding tissue and are fixed in position (for example, the retroperitoneal section of the duodenum usually passes through the transpyloric plane).
|
|
Surgical techniques, using a tube or catheter to drain fluid from the peritoneum, chest, or the pericardium around the heart, often are used in cases of severe blunt trauma to the chest or abdomen, especially when a person is experiencing early signs of shock. In those with low blood-pressure, likely because of bleeding in the abdominal cavity, cutting through the abdominal wall surgically is indicated.
|
|
Most Vipera species have venom that contains both neurotoxic and haemotoxic components. Bites vary widely in severity. V. ammodytes is most likely the one with the most toxic venom. In a study solely involving mice, Brown (1973) shows that the LD50 is about 1.2/mg/kg through an IV, 1.5 mg/Kg when injected in the peritoneum (IP) and 2.0 mg/kg when administered subcutaneously.
|
|
In adolescents or children with ovarian tumors, symptoms can include severe abdominal pain, irritation of the peritoneum, or bleeding. Symptoms of sex cord-stromal tumors produce hormones that can affect the development of secondary sex characteristics. Sex cord-stromal tumors in prepubertal children may be manifested by early puberty; abdominal pain and distension are also common. Adolescents with sex cord-stromal tumors may experience amenorrhea.
|
|
The ovarian ligament is composed of muscular and fibrous tissue; it extends from the uterine extremity of the ovary to the lateral aspect of the uterus, just below the point where the uterine tube and uterus meet. The ligament runs in the broad ligament of the uterus, which is a fold of peritoneum rather than a fibrous ligament. Specifically, it is located in the parametrium.

Mrs Russell and one of the other lodgers, Annie Lee, took Smith to the London Hospital, where she was treated by house surgeon George Haslip. She fell into a coma and died the next day at 9 a.m.Evans and Skinner, pp. 4–7 Medical investigation by the duty surgeon, Dr G. H. Hillier, revealed that a blunt object had been inserted into her vagina, rupturing her peritoneum.

|
Bacteremia can lead to localized infections of the meninges in the brain, the respiratory pleural spaces or lungs, joints, the pericardial sac around the heart, or the peritoneum. In cattle, C. fetus infection is a common cause of pregnancy failure. Intestinal infection in the pregnant female can become septicemic and spread to the reproductive tract, including placenta and fetus, causing placental and/or fetal infections.
|
|
Salpingitis is an infection and inflammation in the Fallopian tubes (salpinges). It is often used synonymously with pelvic inflammatory disease (PID), although PID lacks an accurate definition and can refer to several diseases of the female upper genital tract, such as endometritis, oophoritis, myometritis, parametritis and infection in the pelvic peritoneum. In contrast, salpingitis only refers to infection and inflammation in the fallopian tubes.
|
|
Sometimes the peritoneum completely invests it and forms a distinct but narrow mesocolon. It is in relation, in front, with the convolutions of the ileum and the abdominal walls. The ascending colon is on the right side of the body (barring any malformations). The term right colon is hypernymous to ascending colon in precise use; many casual mentions of the right colon chiefly concern the ascending colon.
|
|
Surgery is usually indicated if intestinal perforation occurs. One study found a 30-day mortality rate of 9% (8/88), and surgical site infections at 67% (59/88), with the disease burden borne predominantly by low-resource countries. For surgical treatment, most surgeons prefer simple closure of the perforation with drainage of the peritoneum. Small-bowel resection is indicated for patients with multiple perforations.
|
|
Retropubic space is a potential avascular space located between the pubic symphysis and the urinary bladder. The retropubic space is a preperitoneal space, located behind the transversalis fascia and in front of peritoneum . Other names for the retropubic space are "Cave of Retzius" or "Retzius' space", named after the Swedish anatomist Anders Retzius (1796-1860). The space is a useful landmark in different gynecological and urological surgeries.
|
|
Of the three types of connection and fluid exchange systems (standard, twin-bag and y-set; the latter two involving two bags and only one connection to the catheter, the y-set uses a single y-shaped connection between the bags involving emptying, flushing out then filling the peritoneum through the same connection) the twin-bag and y-set systems were found superior to conventional systems at preventing peritonitis.
|
|
Kocher maneuver and MLRRD have been used for diverse cases, but they have approximately equivalent outcomes. The peritoneum is incised at the right edge of the duodenum, and the duodenum and the head of pancreas are reflected to the opposite direction; that is, to the left. This is also the name of a manoeuvre used to reduce anterior shoulder dislocations by externally rotating the shoulder, before adducting and internally rotating it.
|
|
CNE is a necrotizing inflammation of the small bowel (especially the jejunum but also the ileum). Clinical results may vary from mild diarrhea to a life-threatening sequence of severe abdominal pain, vomiting (often bloody), bloody stool, ulceration of the small intestine with leakage (perforation) into the peritoneal cavity and possible death within a single day due to peritonitis. Many patients exhibit meteorism and a fever. Fluid can enter the peritoneum.
|
|
Testing for gonorrhea and chlamydia should be performed to make the diagnosis. An endocervical or low vaginal swab should be taken to test for these organisms. Antibody testing is rarely required but may be considered if other tests are non-diagnostic and suspicion is high.Laparoscopy is also rarely required, but may be performed when the diagnosis is uncertain and may reveal "guitar string" adhesions of parietal peritoneum to liver.
|
|
Horses that have cases of infection Anoplocephala perfoliata are at an increased risk of suffering from colic while infected and after being treated. An infected horse can also suffer from peritonitis (inflammation of the peritoneum) as well as secondary infections and abscesses at the site of attachment. Impaction of the intestine is also a possible symptom. In rare cases, the intestinal tract itself can twist and even rupture.
|
|
Uterine rupture is a serious event during childbirth by which the integrity of the myometrial wall is breached. In an incomplete rupture the peritoneum is still intact. With a complete rupture the contents of the uterus may spill into the peritoneal cavity or the broad ligament. A uterine rupture is a life-threatening event for mother and baby as it typically results in severe hemorrhage and can cause perinatal asphyxia.
|
|
Dan Lednicer wrote about this compound in book #6 of his organic drug synthesis series. Batimastat was the first MMPI that went into clinical trials. First results of a Phase I trial appeared in 1994. The drug reached Phase III but was never marketed; mainly because it couldn't be administered orally (as opposed to the newer and chemically similar MMPI marimastat), and injection into the peritoneum caused peritonitis.
|
|
FAST Algorithm FAST is most useful in trauma patients who are hemodynamically unstable. A positive FAST result is defined as the appearance of a dark ("anechoic") strip in the dependent areas of the peritoneum. In the right upper quadrant this typically appears in Morison's Pouch (between the liver and kidney). This location is most useful as it is the place where fluid will collect with a supine patient.
|
|
This peritoneal inflammation, or peritonitis, results in rebound tenderness (pain upon removal of pressure rather than application of pressure). In particular, it presents at McBurney's point, 1/3 of the way along a line drawn from the anterior superior iliac spine to the umbilicus. Typically, point (skin) pain is not present until the parietal peritoneum is inflamed, as well. Fever and an immune system response are also characteristic of appendicitis.
|
|
Diffusion of water to the coprodeum (where urine is stored) from plasma across the epithelium is voided. This void is believed to be caused by the thick mucosal layering of the coprodeum. Common ostriches have two kidneys, which are chocolate brown in color, granular in texture, and lie in a depression in the pelvic cavity of the dorsal wall. They are covered by peritoneum and a layer of fat.

In an 1856 paper he described what were to become known as the "cells of Claudius", which are cells located on the basilar membrane of the inner ear's cochlea. His name is also associated with "Claudius' fossa", now referred to as the ovarian fossa, a depression in the parietal peritoneum of the pelvis. In 1867 he published Das Gehörorgan von Rhytina stelleri ("The hearing organ of Rhytina stelleri ").

The T stages of bowel cancer. Staging is typically made according to the TNM staging system from the WHO organization, the UICC and the AJCC. The Astler-Coller classification (1954) and the Dukes classification (1932) are now less used. T stands for tumor stage and ranges from 0, no evidence of primary tumor, to T4 when the tumor penetrates the surface of the peritoneum or directly invades other organs or structures.

This feature better adapts the shiner to a diet primarily of plant material. It is superficially different from similar members of its genus because of the angle and size of its mouth, head shape, eight anal fin rays, and black edge on its lower lip. It is also one of the few Notropis to have a black peritoneum. Its closest relatives are the Swallowtail Shiner and the Sand Shiner.
|
|
This genus is usually characterized by almost all having a complete lateral line, 8 dorsal fin rays, a premaxillae protactile, and a silvery or speckled peritoneum. As the common name indicates, this species is difficult to classify in the wild because it looks similar to many other shiners. In fact, some even hypothesize that this species is actually a complexity of many cryptic species.Etnier, D.A. and W.C. Starnes. 2001.

The development of the gonads is part of the prenatal development of the reproductive system and ultimately forms the testes in males and the ovaries in females. The gonads initially develop from the mesothelial layer of the peritoneum. The ovary is differentiated into a central part, the medulla, covered by a surface layer, the germinal epithelium. The immature ova originate from cells from the dorsal endoderm of the yolk sac.
|
|
A small uncinate process emerges from below the head, situated behind the superior mesenteric vein and sometimes artery. The neck of the pancreas separates the head of the pancreas, located in the curvature of the duodenum, from the body. The neck is about wide, and sits in front of where the portal vein is formed. The neck lies mostly behind the pylorus of the stomach, and is covered with peritoneum.
|
|
This is a testis in the male and an ovary in the female. At first, the mesonephros and gonadal ridge are continuous, but as the embryo grows the gonadal ridge gradually becomes pinched off from the mesonephros. However, some cells of mesonephric origin join the gonadal ridge. Furthermore, the gonadal ridge still remains connected to the remnant of that body by a fold of peritoneum, namely the mesorchium or mesovarium.

Cochranella was first described by Edward Harrison Taylor in 1951. The current delimitation of this genus follows from the work by Juan Manuel Guayasamin and his colleagues published in 2009 (with some later adjustments). These authors remedied the polyphyly of the genus by partitioning it into several new genera. The diagnostic characteristics of the genus are the following: (1) humeral spines are absent (small spine present in C. litoralis); (2) digestive tract is white (translucent in Cochranella nola) and the lobed liver is covered by a transparent hepatic peritoneum; (3) ventral parietal peritoneum is white anteriorly and transparent posteriorly; (4) webbing between the fingers III–IV is moderate to extensive; (5) bones are green in life; (6) dorsum is lavender in preserved speciments; (7) dentigerous process of the vomer and vomerine teeth are present (absent in C. litoralis); (8) males call from the upper surfaces of leaves and females deposit eggs on the upper sides of leaves along streams; (9) quadratojugal bone is articulating with maxilla.

Peritoneal dialysis (PD) is a type of dialysis which uses the peritoneum in a person's abdomen as the membrane through which fluid and dissolved substances are exchanged with the blood. It is used to remove excess fluid, correct electrolyte problems, and remove toxins in those with kidney failure. Peritoneal dialysis has better outcomes than hemodialysis during the first couple of years. Other benefits include greater flexibility and better tolerability in those with significant heart disease.

In the adult, these connective structures of omentum and mesentery form the peritoneum, and act as an insulating and protective layer while also supplying organs with blood and lymph vessels as well as nerves. Arterial supply to all these structures is from the celiac trunk, and venous drainage is by the portal venous system. Lymph from these organs is drained to the prevertebral celiac nodes at the origin of the celiac artery from the aorta.

It is possible the pain could localize to the left lower quadrant in people with situs inversus totalis. The combination of pain, anorexia, leukocytosis, and fever is classic. Atypical histories lack this typical progression and may include pain in the right lower quadrant as an initial symptom. Irritation of the peritoneum (inside lining of the abdominal wall) can lead to increased pain on movement, or jolting, for example going over speed bumps.

The sign indicates aggravation of the parietal layer of peritoneum by stretching or moving. Positive Blumberg sign is indicative of peritonitis, which can occur in diseases like appendicitis, and may occur in ulcerative colitis with rebound tenderness in the right lower quadrant. However, in recent years the value of rebound tenderness has been questioned, since it may not add any diagnostic value beyond the observation that the patient has severe tenderness.Liddington MI, Thomson WHF.

The Cherney incision begins when the skin is cut 2-3 centimeters above the pubic symphysis and the surgeon dissects down to the rectus abdominis muscle. The surgeon then uses blunt dissection with the fingers to separate the tendons from the bladder before cutting the tendons 1-2 centimeters above the pubic symphysis. The muscles are then lifted away, toward the patient's head (cephalad). Then, the peritoneum can be cut and the surgery can proceed.

The most distinguishing characteristic of this species is the black to dusky in color of its peritoneum (the lining of the abdominal cavity). It is one of the "typical" North American shads. They are often confused with alewifes because blueback shad and alewives are difficult to distinguish from one another, and together these two species are often regarded collectively as "river herring". Alewives have larger eyes, greater body depth, and pearly to white peritoneal linings.

The lateral line pores at front are outlined in black while the lips are yellow to pale orange as are the dorsal, caudal, and pectoral fins. It often shows a dusky stripe along the back with another stripe along the silvery flank which is dusky at the head end shading to black at the rear. It is white below with a silvery peritoneum. It grows to in standard length or total length.

The cecum or caecum is a pouch within the peritoneum that is considered to be the beginning of the large intestine. It is typically located on the right side of the body (the same side of the body as the appendix, to which it is joined). The word cecum (, plural ceca ) stems from the Latin caecus meaning blind. It receives chyme from the ileum, and connects to the ascending colon of the large intestine.

Malignant mesothelioma is an aggressive and incurable tumour caused by asbestos arising from mesothelial cells of the pleura, peritoneum (the lining of the abdominal cavity) and rarely elsewhere. Pleural mesothelioma is the most common type of mesothelioma, representing about 75 percent of cases. Peritoneal mesothelioma is the second most common type, consisting of about 10 to 20 percent of cases. Mesothelioma appears from 20 to 50 years after the initial exposure to asbestos.

Each of the symptoms of situs ambiguus must be managed with appropriate treatment dependent upon the organ system involved. Intestinal malrotation is treated surgically using the Ladd procedure. This procedure widens a fold in the peritoneum so that the intestines can be placed in non-rotated formation. It is not possible to return the bowel to a normal morphology However, 89% of patients that undergo the Ladd surgery experience a complete resolution of symptoms.

The falciform ligament functions to attach the liver to the posterior portion of the anterior body wall. The visceral surface or inferior surface is uneven and concave. It is covered in peritoneum apart from where it attaches the gallbladder and the porta hepatis. The fossa of gall bladder lies to the right of the quadrate lobe, occupied by the gallbladder with its cystic duct close to the right end of porta hepatis.

In particular, it increasing the rate of head reappearance in beheaded worms. And, MaR1 reduced neuropathic pain in a mouse model by inhibiting a neuron ion channel, TRPV1, and thereby blocking capsaicin-induced inward currents and neuron excitation. Mar2 possess at least some of the activities ascribed to MaR1. It enhances human macrophage phagocytosis of particles and efferocytosis of apoptotic human neutrophils and reduces neutrophil infiltration into the inflamed peritoneum of mice.

Cryothenia amphitreta is a species of marine pelagic fish belonging to the family Nototheniidae. It is found in the Antarctic Ross Sea. It has an unusual body structure: the pelvic fins reach only halfway from the pelvic-fin base to the anal origin, and the second dorsal-fin insertion is particularly advanced compared to the anal origin. C. amphitreta is coloured purple-gold with black linings on the mouth, gills cavities, and peritoneum.

The size of the heart varies among the different animal groups, with hearts in vertebrates ranging from those of the smallest mice (12 mg) to the blue whale (600 kg). In vertebrates, the heart lies in the middle of the ventral part of the body, surrounded by a pericardium. which in some fish may be connected to the peritoneum. The SA node is found in all amniotes but not in more primitive vertebrates.

The murder took place at the bus stop of the Shalom Theater, near Varshavskaya Metro Station. On March 27, Petrova killed a 60-year-old pensioner, Nikolai Zhabin, by cutting his throat. Subsequently, Petrova committed three more attempted murders (all victims survived), and was suspected of another attack, but was not charged due to lack of evidence. All attacks were carried out in the same way - stab wounds to the peritoneum and neck.

Seminal vesiculitis (also known as spermatocystitis) is an inflammation of the seminal vesicles, most often caused by bacterial infection. Symptoms can include vague back or lower abdominal pain; pain of the penis, scrotum or peritoneum; painful ejaculation; blood in the semen on ejaculation; irritative and obstructive voiding symptoms; and impotence. Infection may be due to sexually transmitted infections, as a complication of a procedure such as prostate biopsy. It is usually treated with antibiotics.

The shiner only has pharyngeal teeth (teeth located on the back of the fish's throat on its gill arches), similar to the teeth of other omnivorous shiners. The Cape Fear Shiner's eyes are moderately sized and on the side of the fish's head. It has eight anal fin rays. The shiner's distinctive long dark intestines are coiled and visible through the fish's belly wall and it also has a distinctive black peritoneum.

The sigmoid arteries, two or three in number, run obliquely downward and to the left behind the peritoneum and in front of the psoas major, ureter, and internal spermatic vessels. They originate from the inferior mesenteric artery branch of the abdominal aorta. Their branches supply the lower part of the descending colon, the iliac colon, and the sigmoid or pelvic colon; anastomosing above with the left colic, and below with the superior hemorrhoidal artery.
|
|
The ileocolic artery is the lowest branch arising from the concavity of the superior mesenteric artery. It passes downward and to the right behind the peritoneum toward the right iliac fossa, where it divides into a superior and an inferior branch; the inferior gives rise to the appendicular artery and anastomoses with the end of the superior mesenteric artery, the superior with the right colic artery. It supplies the cecum, ileum, and appendix.

Retzius studied many different skull types from different races, because the skulls were so different from each race he believed that the races had a separate origin.Peter Rowley-Conwy, From Genesis to Prehistory: The Archaeological Three Age System and its Contested Reception in Denmark, Britain, and Ireland, 2007, p. 120 The retropubic space of Retzius is named after him. The peritoneum lies deep to the posterior layer of transversalis fascia and is very adherent to it.

Mesothelioma is a rare primary tumour of the connective tissue, originates in the serous membranes of the pleura, peritoneum or pericardium. Peritoneal involvement is reported in 25% of cases. Imaging features include ascites, diffuse irregular nodular peritoneal thickening, invasion of omenta and mesentery with the formation of omental cakes, and mesenteric masses and bowel wall thickening. Coexistence of pleural abnormalities with positive occupational asbestos exposure history in absence detectable primary tumour goes more in favor of mesothelioma.

During laparoscopy (laparoscopic surgery or minimally invasive surgery), it is necessary to insufflate the abdominal cavity (i.e. inflate the abdomen like a balloon) with medical-grade carbon dioxide (CO2) to create a viewing and working space for the surgery. The CO2 may be unconditioned, or conditioned with heat, or with humidification and heat. During insufflation, the peritoneum (an extensive delicate membrane that lines the abdominal cavity and covers most of the abdominal organs) is exposed to the CO2.

In some, the pharyngeal part of the animal degenerates, and the abdomen breaks up into patches of germinal tissue, each combining parts of the epidermis, peritoneum, and digestive tract, and capable of growing into new individuals. In yet others, budding begins shortly after the larva has settled onto the substrate. In the family Didemnidae, for instance, the individual essentially splits into two, with the pharynx growing a new digestive tract and the original digestive tract growing a new pharynx.

Sipunculans do not have a vascular blood system. Fluid transport and gas exchange are instead accomplished by the coelom, which contains the respiratory pigment haemerythrin, and the separate tentacular system, the two being separated by an elaborate septum. The coelomic fluid contains five types of coelomic cells: haemocytes, granulocytes, large multinuclear cells, ciliated urn-shaped cells and immature cells. The ciliated urn cells may also be attached to the peritoneum and assist in waste filtering from the coelomic fluid.
|
|
The iliac colon is situated in the left iliac fossa, and is about 12 to 15 cm. long. It begins at the level of the iliac crest, where it is continuous with the descending colon, and ends in the sigmoid colon at the superior aperture of the lesser pelvis. It curves downward and medialward in front of the Iliacus and Psoas, and, as a rule, is covered by peritoneum on its sides and anterior surface only.

Gliomatosis peritonei, a rare condition often associated with immature ovarian teratoma, is characterized by the presence of mature glial implants in the peritoneum. Yoon et al. (2012), reported that immature ovarian teratoma patients with Gliomatosis peritonei have larger tumors, more frequent recurrence and higher CA-125 levels than immature ovarian teratoma patients without gliomatosis peritonei. A high degree of immaturity in the primary tumor, one that corresponds with a grade 3 diagnosis is a sign of poor prognosis.

Frontal view of an inguinal hernia (right). Incarcerated umbilical hernia with surrounding inflammation By far the most common hernias develop in the abdomen, when a weakness in the abdominal wall evolves into a localized hole, or "defect", through which adipose tissue, or abdominal organs covered with peritoneum, may protrude. Another common hernia involves the spinal discs and causes sciatica. A hiatus hernia occurs when the stomach protrudes into the mediastinum through the esophageal opening in the diaphragm.

An abdominal mass is any localized enlargement or swelling in the human abdomen. Depending on its location, the abdominal mass may be caused by an enlarged liver (hepatomegaly), enlarged spleen (splenomegaly), protruding kidney, a pancreatic mass, a retroperitoneal mass (a mass in the posterior of the peritoneum), an abdominal aortic aneurysm, or various tumours, such as those caused by abdominal carcinomatosis and omental metastasis. The treatments depend on the cause, and may range from watchful waiting to radical surgery.

A primary abdominal pregnancy refers to a pregnancy that first implanted directly in the peritoneum, save for the tubes and ovaries; such pregnancies are very rare, only 24 cases having been reported by 2007. Typically an abdominal pregnancy is a secondary implantation which means that it originated from a tubal (less common an ovarian) pregnancy and re-implanted. Other mechanisms for secondary abdominal pregnancy include uterine rupture, rupture of a uterine rudimentary horn and fimbrial abortion.

Grey Turner's sign refers to bruising of the flanks, the part of the body between the last rib and the top of the hip. The bruising appears as a blue discoloration, and is a sign of retroperitoneal hemorrhage, or bleeding behind the peritoneum, which is a lining of the abdominal cavity. Grey Turner's sign takes 24–48 hours to develop, and can predict a severe attack of acute pancreatitis. Grey Turner's sign may be accompanied by Cullen's sign.

An enterocele is a protrusion of the small intestines and peritoneum into the vaginal canal.Merck Manuals > Cystoceles, Urethroceles, Enteroceles, and Rectoceles Last full review/revision December 2008 by S. Gene McNeeley It may be treated transvaginallyVaginal Repair of Enterocele By Clifford R. Wheeless, Jr., M.D. and Marcella L. Roenneburg, M.D. Retrieved Dec 2010 or by laparoscopy. An enterocele may also obstruct the rectum, leading to symptoms of obstructed defecation. Enteroceles can form after treatment for gynecological cancers.

Malignancy is characterized by local invasion and metastases, usually to the liver, omentum and peritoneum. However, cases of metastases to bone, pleura, lungs and retroperitoneum have been seen. In distinction to gastric adenocarcinoma or gastric/small bowel lymphoma, malignant lymphadenopathy (swollen lymph nodes) is uncommon (<10%) and thus imaging usually shows absence of lymph node enlargement. If metastases are not present, other radiologic features suggesting malignancy include: size (>5 cm), heterogeneous enhancement after contrast administration and ulcerations.

The bare area of the liver (nonperitoneal area) is a large triangular area on the diaphragmatic surface of the liver, devoid of peritoneal covering. It is attached directly to the diaphragm by loose connective tissue. The coronary ligament represent reflections of the visceral peritoneum covering the liver onto the diaphragm. As such, between the two layers of the coronary ligament lies the bare area of the liver, and this is attached to the diaphragm by areolar tissue.

3D model of urinary system The urinary system refers to the structures that produce and transport urine to the point of excretion. In the human urinary system there are two kidneys that are located between the dorsal body wall and parietal peritoneum on both the left and right sides. The formation of urine begins within the functional unit of the kidney, the nephrons. Urine then flows through the nephrons, through a system of converging tubules called collecting ducts.

A distinctive feature of the gallbladder is the presence of Rokitansky–Aschoff sinuses, deep outpouchings of the mucosa that can extend through the muscular layer, and which indicate adenomyomatosis. The muscular layer is surrounded by a layer of connective and fat tissue. The outer layer of the fundus of gallbladder, and the surfaces not in contact with the liver, are covered by a thick serosa, which is exposed to the peritoneum. The serosa contains blood vessels and lymphatics.

This operation involved removal of the uterus, parametrium, tissues surrounding the upper vagina, and pelvic lymph nodes, but leaving the ovaries intact. Afterwards, Wertheim surgery became a fairly common, although risky procedure for cervical cancer. He conducted important research of gonorrhea in the female genital tract, and was the first physician to demonstrate the presence of gonococcus in the peritoneum. Also, he discovered that gonococcus grows best on a culture of agar mixed with human blood serum.

In the male, the peritoneum encircles the sigmoid colon, from which it is reflected to the posterior wall of the pelvis as a fold, the sigmoid mesocolon. It then leaves the sides and, finally, the front of the rectum, and is continued on to the upper ends of the seminal vesicles and the bladder; on either side of the rectum it forms a fossa, the pararectal fossa, which varies in size with the distension of the rectum.
|
|
First, a surgical incision is made of the peritoneum overlying the Sacrum#Promontory and extending this incision toward the aortic bifurcation. The inferior mesenteric artery is then identified as the left lateral border of the dissection. A surgical plane can then be carefully developed between the inferior mesenteric artery and the left common iliac vein. The sacral promontory area is identified and can be infiltrated with vasoconstrictive solution or with the use of electrosurgery to reduce blood loss.

The outermost layer of the gastrointestinal wall consists of several layers of connective tissue and is either adventitia or serosa. Regions of the gastrointestinal tract within the peritoneum (called Intraperitoneal) are covered with serosa. This structure consists of connective tissue covered by a simple squamous epithelium, called the mesothelium, which reduces frictional forces during digestive movements. The intraperitoneal regions include most of the stomach, first part of the duodenum, all of the small intestine, caecum and appendix, transverse colon, sigmoid colon and rectum.

99 The parietal and visceral peritonea are layers of the peritoneum named depending on their function/location. It is one of the spaces derived from the coelomic cavity of the embryo, the others being the pleural cavities around the lungs and the pericardial cavity around the heart. It is the largest serosal sac, and the largest fluid-filled cavity, in the body and secretes approximately 50 ml of fluid per day. This fluid acts as a lubricant and has anti-inflammatory properties.

Lumbar plexus and its branches. Since the Lumbar plexus and Sacral plexus are interconnected, they are sometimes referred to as the Lumbosacral plexus. The intercostal nerves that give rami to the chest and to the upper parts of the abdominal wall efferent motor innervation and to the pleura and peritoneum afferent sensory innervation are the only ones that do not originate from a plexus. The ventral rami of L1-L5 spinal nerves with a contribution of T12 form Lumbar plexus.

Chronically infected individuals who become immunosuppressed due to HIV infection can suffer particularly severe and distinct disease, most commonly characterized by inflammation in the brain and surrounding tissue or brain abscesses. Symptoms vary widely based on the size and location of brain abscesses, but typically include fever, headaches, seizures, loss of sensation, or other neurological issues that indicate particular sites of nervous system damage. Occasionally, these individuals also experience acute heart inflammation, skin lesions, and disease of the stomach, intestine, or peritoneum.

Failed obliteration of the processus vaginalis allows serous fluid to collect around the testes via a communicating connection between the tunica vaginalis and the peritoneum. The resulting hydrocele presents as a painless enlargement of the scrotum, similar to what may be encountered with testicular neoplasms. A convenient method to differentiate the conditions is to transilluminate the scrotum, as the hydrocele will appear a soft red while a solid tumor will not transmit light. Any uncertainty should be followed up with an ultrasound.

Sea urchins are spiky echinoderms with spherical bodies which usually contain five gonads. They move slowly, feed mostly on seaweed, and are important for the diet of sea otters. Sea urchins are dioecious, having separate male and female sexes, although there is generally no easy way to distinguish the two. The gonads are lined with muscles underneath the peritoneum, and these allow the animal to squeeze its gametes through the duct and into the surrounding sea water, where fertilization takes place.

Serous carcinoma is a Type II endometrial tumor that makes up 5–10% of diagnosed endometrial cancer and is common in postmenopausal women with atrophied endometrium and black women. Serous endometrial carcinoma is aggressive and often invades the myometrium and metastasizes within the peritoneum (seen as omental caking) or the lymphatic system. Histologically, it appears with many atypical nuclei, papillary structures, and, in contrast to endometrioid adenocarcinomas, rounded cells instead of columnar cells. Roughly 30% of endometrial serous carcinomas also have psammoma bodies.

Hereditary breast-ovarian cancer syndrome is an autosomal dominant genetic disorder caused by genetic mutations of the BRCA1 and BRCA2 genes. In women this disorder primarily increases the risk of breast and ovarian cancer, but also increases the risk of fallopian tube carcinoma and papillary serous carcinoma of the peritoneum. In men the risk of prostate cancer is increased. Other cancers that are inconsistently linked to this syndrome are pancreatic cancer, male breast cancer, colorectal cancer and cancers of the uterus and cervix.

In amniotes and some invertebrates the coelom is the large cavity lined by mesothelium, an epithelium derived from mesoderm. Organs formed inside the coelom can freely move, grow, and develop independently of the body wall while fluid in the peritoneum cushions and protects them from shocks. Arthropods and most molluscs have a reduced (but still true) coelom, usually the pericardial cavity and the gonocoel. Their principal body cavity is the hemocoel or haeomocoel of an open circulatory system, often derived from the blastocoel.

The trauma ex-lap is the most comprehensive ex- lap, usually undertaken after evidence of internal bleeding (a positive FAST, DPL, or other overwhelming evidence for internal hemorrhage). A midline incision is carried down to the linea alba and the fascia is incised. The peritoneum is entered and any immediate, life-threatening bleeding is identified and controlled. The lateral, superior, and anterior surfaces of the liver are packed with sponges, and the superior and lateral spaces around the spleen are similarly packed.
|
|
Other epithelial cells line the insides of the lungs, the gastrointestinal tract, the reproductive and urinary tracts, and make up the exocrine and endocrine glands. The outer surface of the cornea is covered with fast-growing, easily regenerated epithelial cells. A specialised form of epithelium, endothelium, forms the inner lining of blood vessels and the heart, and is known as vascular endothelium, and lining lymphatic vessels as lymphatic endothelium. Another type, mesothelium, forms the walls of the pericardium, pleurae, and peritoneum.

An autopsy was performed later on the morning of McKinley's death; Mann led a team of 14 physicians. They found the bullet had passed through the stomach, then through the transverse colon, and vanished through the peritoneum after penetrating a corner of the left kidney. There was also damage to the adrenal glands and pancreas. Mynter, who participated in the autopsy, later stated his belief that the bullet lodged somewhere in the back muscles, though this is uncertain as it was never found.

It is located close to the right of the fossa, between the bare area and the caudate lobe, and immediately above the renal impression. The greater part of the suprarenal impression is devoid of peritoneum and it lodges the right suprarenal gland. Medial to the renal impression is a third and slightly marked impression, lying between it and the neck of the gall bladder. This is caused by the descending portion of the duodenum, and is known as the duodenal impression.

In such a situation the placenta sits on the intra-abdominal organs or the peritoneum and has found sufficient blood supply. This is generally bowel or mesentery, but other sites, such as the renal (kidney), liver or hepatic (liver) artery or even aorta have been described. Support to near viability has occasionally been described, but even in Third World countries, the diagnosis is most commonly made at 16 to 20 weeks' gestation. Such a fetus would have to be delivered by laparotomy.

2 epiploic appendages next to an ovary in pelvic ultrasound The epiploic appendices (or appendices epiploicae, or epiploic appendages, or appendix epiploica, or omental appendices) are small pouches of the peritoneum filled with fat and situated along the colon, but are absent in the rectum. They are chiefly appended to the transverse and sigmoid parts of the colon, however, their function is unknown. The appendages can become inflamed, but painful process known as epiploic appendagitis which can mimic acute appendicitis and other conditions.

Traumatic rupture of the spleen on contrast enhanced axial CT (portal venous phase) Splenic hematoma resulting in free abdominal blood Splenic rupture is usually evaluated by FAST ultrasound of the abdomen.Mattox 2012, p. 566 Generally this is not specific to splenic injury; however, it is useful to determine the presence of free floating blood in the peritoneum. A diagnostic peritoneal lavage, while not ideal, may be used to evaluate the presence of internal bleeding a person who is hemodynamically unstable.

An ovary from one female examined contained about 30,000 eggs. Like all other eels, the snubnosed eel undergoes a leptocephalus larval stage that metamorphoses into a juvenile form resembling the adult. Leptocephali belonging to this species have yet to be identified, but based on the appearance of the metamorphic stage, they likely have long bodies with short heads and small mouths, and little to no body pigmentation. Metamorphic fish are white, with the black peritoneum clearly visible; one known metamorphic specimen measured long.

The parietal portion lines the cavity in varying quantities in different situations. It is especially abundant on the posterior wall of the abdomen, and particularly around the kidneys, where it contains much fat. On the anterior wall of the abdomen, except in the pubic region, and on the lateral wall above the iliac crest, it is scanty, and here the transversalis fascia is more closely connected with the peritoneum. There is a considerable amount of extraperitoneal connective tissue in the pelvis.

Illustration of a hammerjaw The large head is dominated by a massive, truncated lower jaw and large, high-set eyes. The lower jaw has a dark, almost black distal end, "chin". The lower jaw possesses at least one pair of oversized, transparent, and dagger-like teeth; the palatines possess 1-4 pairs of slightly smaller teeth. The body itself is scaleless and laterally compressed; it is covered in iridescent, silvery-gray guanine with the dark peritoneum peeking through in places.

Retrieved on March 14, 2009. Adult D. longipes exhibit paedomorphic characteristics found in the juveniles of other opisthoproctids, such as poorly developed muscles (for example the lack of ventral muscles, meaning the gut is enclosed only by the peritoneum and the skin), rudimentary scales and coloration, and the placement of the pectoral and pelvic fins on peduncles that are not connected to the body by muscles. Developed gonads have been observed in a male and a female. Their lifespan is 5 years.

The recto-vesical pouch is the pocket that lies between the rectum and the urinary bladder in human males and other male mammals. It is lined by peritoneum and at its base is the rectoprostatic fascia (Denonvillier's fascia). When a man is upright or supine, the recto-vesical pouch is the lowest part of his peritoneal cavity. Because of this, peritoneal fluid and other fluids that enter the peritoneal cavity, including ascites, blood and pus, tend to collect in this pouch.

|
The mesentery is a double layer of visceral peritoneum that attaches to the gastrointestinal tract. There are often blood vessels, nerves, and other structures between these layers. The space between these two layers is technically outside of the peritoneal sac, and thus not in the peritoneal cavity. The potential space between these two layers is the peritoneal cavity, filled with a small amount (about 50 mL) of slippery serous fluid that allows the two layers to slide freely over each other.

These include: the colour of the peritoneum (black for L. budegassa and white for L. piscatorius) and the number of rays in the second dorsal fin (L. budegassa, 9–10 and L. piscatorius, 11–12). Also, minor differences in their distribution occur. Black anglerfish tend to have a more southern distribution (Mediterranean and eastern North Atlantic from the British Isles to Senegal), whereas the white anglerfish are distributed further north, (Mediterranean, Black Sea and eastern North Atlantic from the Barents Sea to the Strait of Gibraltar).

The pattern of metastasis is different for gastric signet cell carcinoma than for intestinal-type gastric carcinoma. The SRCC tumor is often seen in the peritoneum and has also been known to spread to lymphatic permeation of the lungs and to the ovaries, creating Krukenberg tumors. Cases of gastric carcinomas metastasizing to the breast and forming signet-ring cells have also been reported. One study suggests that when signet-ring cells are found in a breast tumor, the presence of gastric cancer should also be considered.

The posterior layer of the coronary ligament is reflected from the lower margin of the bare area and is continuous with the right layer of the lesser omentum. The anterior and posterior layers converge on the right and left sides of the liver to form the right triangular ligament and the left triangular ligament, respectively. In between the two sides of the anterior layer, the reflection of peritoneum has an inferior continuation termed the falciform ligament. The falciform ligament contains the round ligament of liver.

Infection may spread from the urethra in the penis to nearby structures, including the testicles (epididymitis/orchitis), or to the prostate (prostatitis). Men who have had a gonorrhea infection have a significantly increased risk of having prostate cancer. In symptomatic women, the primary symptoms of genitourinary infection are increased vaginal discharge, burning with urination (dysuria), increased urge to urinate, pain with intercourse, or menstrual abnormalities. Pelvic inflammatory disease results if N. gonorrhoeae ascends into the pelvic peritoneum (via the cervix, endometrium, and fallopian tubes).

During the withdrawal, Julian's forces suffered several attacks from Sassanid forces. In one such engagement on 26 June 363, the indecisive Battle of Samarra near Maranga, Julian was wounded when the Sassanid army raided his column. In the haste of pursuing the retreating enemy, Julian chose speed rather than caution, taking only his sword and leaving his coat of mail.Ammianus Marcellinus, Res Gestae, 25.3.3 He received a wound from a spear that reportedly pierced the lower lobe of his liver, the peritoneum and intestines.

This asymmetric expansion creates two curvatures, with the ventral side creating the lesser curvature and the dorsal side creating the greater curvature. The expanding dorsal stomach wall then rotates the on its transverse plane, pulling its caudal portion upward and forcing the upper duodenum into a C shape. This rotation positions the left vagus nerve anteriorly and right vagus nerve posteriorly. While the hindgut and midgut are only attached dorsally to the body wall by a fold of peritoneum, the foregut also has a ventral attachment.

Primary peritoneal cancer or carcinoma is also known as serous surface papillary carcinoma, primary peritoneal carcinoma, extra-ovarian serous carcinoma, primary serous papillary carcinoma, psammomacarcinoma. It was historically classified under "carcinoma of unknown primary" (CUP). Primary peritoneal cancer (PPC, or PPCa) is a cancer of the cells lining the peritoneum, or abdominal cavity. Histomorphological and molecular biological characteristics suggest that serous carcinomas, which include ovarian serous carcinoma, uterine serous carcinoma, Fallopian tube serous carcinoma, cervical serous carcinoma, and primary peritoneal serous carcinoma really represent one entity.

Vaginal expander ZSI 200 NS ZSI 200 NS vaginal expander stretching the female vagina Many surgical procedures have been developed to create a neovagina, as none of them is ideal. Surgical intervention should only be considered after non-surgical pressure dilation methods have failed to produce a satisfactory result. Neovaginoplasty can be performed using skin grafts, a segment of bowel, ileum, peritoneum, an absorbable adhesion barrier (Interceed, made by Johnson & Johnson), buccal mucosa, amnion, dura mater. or with the support of vaginal stents/expanders.

The spermatic cord is the cord-like structure in males formed by the vas deferens (ductus deferens) and surrounding tissue that runs from the deep inguinal ring down to each testicle. Its serosal covering, the tunica vaginalis, is an extension of the peritoneum that passes through the transversalis fascia. Each testicle develops in the lower thoracic and upper lumbar region and migrates into the scrotum during its descent it carries along with it vas deferens, its vessels, nerves etc. There is one on each side.

Depending on the extent of the cancer, procedures may include a bilateral salpingo- oophorectomy, biopsies throughout the peritoneum and abdominal lymphatic system, omentectomy, splenectomy, bowel resection, diaphragm stripping or resection, appendectomy, or even a posterior pelvic exenteration. To fully stage ovarian cancer, lymphadenectomy can be included in the surgery, but a significant survival benefit to this practice may not happen. This is particularly important in germ cell tumors because they frequently metastasize to nearby lymph nodes. If ovarian cancer recurs, secondary surgery is sometimes a treatment option.

After the application of local anesthesia, a vertical skin incision is made one third of the distance from the umbilicus to the pubic symphysis. The linea alba is divided and the peritoneum entered after it has been picked up to prevent bowel perforation. A catheter is inserted towards the pelvis and aspiration of material attempted using a syringe. If no blood is aspirated, 1 litre of warm 0.9% saline is infused and after a few (usually 5) minutes this is drained and sent for analysis.

It has been suggested that suction drains placed during surgery and non-peritonisation (not closing the posterior peritoneum) may reduce the possibility of lymphocele development. Smaller lymphoceles can be managed expectantly, and many lesions will regress over time. For symptomatic lesions a number of approaches are available and include fine needle aspiration with US or CT guidance, catheter insertion and drainage (with possible use of sclerosants), and surgical drainage. Sex and masturbation may cause the lymphocele to grow if it is in the genital area.

Exposure to asbestos fibers has been recognized as an occupational health hazard since the early 20th century. Numerous epidemiological studies have associated occupational exposure to asbestos with the development of pleural plaques, diffuse pleural thickening, asbestosis, carcinoma of the lung and larynx, gastrointestinal tumors, and diffuse malignant mesothelioma of the pleura and peritoneum. Asbestos has been widely used in many industrial products, including cement, brake linings, gaskets, roof shingles, flooring products, textiles, and insulation. Commercial asbestos mining at Wittenoom, Western Australia, took place from 1937 to 1966.

The renal capsule surrounds the functional tissue of the kidney, and is itself surrounded by a fatty adipose capsule, fascia, and fat. From the inner part of the kidney to outside the kidney, the positioning of the capsule is: # renal medulla # renal cortex # renal capsule # adipose capsule of kidney (or perirenal fat, or perinephric fat) # renal fascia # pararenal fat # peritoneum (anteriorly), and transverse fascia (posteriorly). Sometimes the adipose capsule of the kidney also known as the perirenal fat, is regarded as a part of the renal capsule.

The ascending portion of the duodenum ascends on the left side of the aorta, as far as the level of the upper border of the second lumbar vertebra, where it turns abruptly forward to become the jejunum, forming the duodenojejunal flexure. The duodenojejunal flexure is surrounded by the suspensory muscle of the duodenum. It lies in front of the left Psoas major and left renal vessels, and is covered in front, and partly at the sides, by peritoneum continuous with the left portion of the mesentery.

The operation started at 02:00 local time on 1 May with the help of a driver and meteorologist, who provided instruments and held a mirror so Rogozov could observe areas not directly visible. Rogozov lay in a semi-reclining position, half-turned to his left side. A solution of 0.5% novocaine was used for local anesthesia of the abdominal wall. Rogozov made a 10–12 cm incision of the abdominal wall, but while opening the peritoneum he accidentally cut the cecum and had to suture it.

Hydrosalpinx may be diagnosed using ultrasonography as the fluid filled elongated and distended tubes display their typical echolucent pattern. However, a small hydrosalpinx may be missed by sonography. During an infertility work-up a hysterosalpingogram (HSG), an X-ray procedure that uses a contrast agent to image the fallopian tubes, shows the retort-like shape of the distended tubes and the absence of spillage of the dye into the peritoneum. If, however, there is a tubal occlusion at the utero-tubal junction, a hydrosalpinx may go undetected.

The McIndoe procedure uses a split-thickness skin graft from the patient where it is placed over an obturator and sewn at the ends to from a tube with one closed end. A transverse incision at the vaginal dimple and a small cavity is made at the level of the peritoneum by the surgeon. The skin graft and obturator are inserted into the vagina vault and secured to the labia minora. Synthetic skin grafts are also an alternative, eliminating the need for skin grafts from patients.

Greater and lesser omentum The greater omentum is the larger of the two peritoneal folds. It consists of a double sheet of peritoneum, folded on itself so that it has four layers. The two layers of the greater omentum descend from the greater curvature of the stomach and the beginning of the duodenum. They pass in front of the small intestines, sometimes as low as the pelvis, before turning on themselves, and ascending as far as the transverse colon, where they separate and enclose that part of the intestine.

A fold of peritoneum, the phrenicocolic ligament is continued from the left colic flexure to the thoracic diaphragm opposite the tenth and eleventh ribs; it passes below and serves to support the spleen, and therefore has received the name of sustentaculum lienis. Friedrich Wilhelm Hensing The phrenicocolic ligament is also called Hensing's ligament after Friedrich Wilhelm Hensing (1719–1745), a German professor for medicine in Gießen.Hensing ligament in The Free Dictionary by Farlex, Medical Eponyms, Farlex, 2012.Friedrich W. Hensing in The Free Dictionary by Farlex, Medical Eponyms, Farlex, 2012.

The retroperitoneum or retroperitnium is an anatomical region that includes the peritoneum-covered organs and tissues that make up the posterior wall of the abdominal cavity and the pelvic space - which extends behind to the abdominal cavity. Definitions vary and can also can include the region of the wall of the pelvic basin. The portion of the retroperitoneum that is posterior wall of the abdomen and superior to the iliac vessels is of importance in gynecological oncology. This is the region where para-aortic and paracaval lymphadenectomies are done.

Patients who develop peritonitis may get localized abscesses in the right or left subphrenic space. The right side is more common due to the high frequency of ruptured appendices and perforated duodenal ulcers. Two common approaches to draining a subphrenic abscess are 1) incision inferior to or through the bed of the 12th rib (no need to create an opening in the pleura or peritoneum) 2) an anterior subphrenic abscess is often drained through a subcostal incision located inferior and parallel to the right costal margin. It is also associated with peritonitis.

Two chaetognath species, Caecosagitta macrocephala and Eukrohnia fowleri, have bioluminescent organs on their fins. Chaetognaths swim in short bursts using a dorso-ventral undulating body motion, where their tail fin assists with propulsion and the body fins with stabilization and steering. Some species are known to use the neurotoxin tetrodotoxin to subdue prey. The body cavity is lined by peritoneum, and therefore represents a true coelom, and is divided into one compartment on each side of the trunk, and additional compartments inside the head and tail, all separated completely by septa.

Cross section of Terrazoanthus onoi (Zoantharia: Hydrozoanthidae) showing complete and incomplete mesenteries In zoology, a mesentery is a membrane inside the body cavity of an animal. The term identifies different structures in different phyla: in vertebrates it is a double fold of the peritoneum enclosing the intestines; in other organisms it forms complete or incomplete partitions of the body cavity, whether that is the coelom or, as in the Anthozoa, the gastrovascular cavity. The word "mesentery" is derived from the Greek mesos, "in the middle" and enteron, an "intestine".

Immature teratomas usually only affect one ovary (10% co-occur with dermoid cysts) and usually metastasize throughout the peritoneum. They can also cause mature teratoma implants to grow throughout the abdomen in a disease called growing teratoma syndrome; these are usually benign but will continue to grow during chemotherapy, and often necessitate further surgery. Unlike mature teratomas, immature teratomas form many adhesions, making them less likely to cause ovarian torsion. There is no specific marker for immature teratomas, but carcinoembryonic antigen (CEA), CA-125, CA19-9, or AFP can sometimes indicate an immature teratoma.

An abdominal pregnancy can be regarded as a form of an ectopic pregnancy where the embryo or fetus is growing and developing outside the womb in the abdomen, but not in the Fallopian tube, ovary or broad ligament. Because tubal, ovarian and broad ligament pregnancies are as difficult to diagnose and treat as abdominal pregnancies, their exclusion from the most common definition of abdominal pregnancy has been debated. Others—in the minority—are of the view that abdominal pregnancy should be defined by a placenta implanted into the peritoneum.

In debulking, the surgeon attempts to remove as much tumor as possible. CRS or cytoreductive surgery involves surgical removal of the peritoneum and any adjacent organs which appear to have tumor seeding. Since the mucus tends to pool at the bottom of the abdominal cavity, it is common to remove the ovaries, fallopian tubes, uterus, and parts of the large intestine. Depending upon the spread of the tumor, other organs might be removed, including but not limited to the gallbladder, spleen, and portions of the small intestine and/or stomach.

Tertiary peritonitis (also known as recurrent peritonitis) is the inflammation of the peritoneum which persists for 48 hours after a surgery that has been successfully carried out in adequate surgical conditions. Tertiary peritonitis is usually the most delayed and severe consequence of nosocomial intra- abdominal infection. Patients who acquire tertiary peritonitis are usually admitted to ICU due to the critical, life-threatening nature of the condition which can lead to multi-organ failure despite treatment and has a high mortality rate of 60%. Signs and symptoms of tertiary peritonitis include fever, hypotension and abdominal pain.

There are five different types of soft tissue preserved in the type specimen of Mauriciosaurus. The first type consists of a largely amorphous glossy black material, bearing some traces of fibres, or wrinkles, which is preserved only within the body cavity, mostly on the right side of the torso. This most likely represents the heavily-pigmented peritoneum, which would have lined the inside of the body cavity in life. Another type of tissue consists of dark grey, thin, and rectangular structures long and wide, organized in parallel rows.

Rothia dentocariosa (previously known as Stomatococcus mucilaginosus) is a species of Gram-positive, round- to rod-shaped bacteria that is part of the normal community of microbes residing in the mouth and respiratory tract. First isolated from dental caries, Rothia dentocariosa is largely benign, but does very rarely cause disease. The most common Rothia infection is endocarditis, typically in people with underlying heart valve disorders. Literature case reports show other tissues that are rarely infected include the peritoneum, tonsils, lung, cornea, inner layers of the eye (Endophthalmitis) and brain and intercranial tissues.

Macroscopic lesions in affected fish are typical of an acute systemic disease with strong congestion in the internal organs and different levels of hemorrhages in the swim bladder, intestine, liver, peritoneum, spleen and kidney. Also, enlargement of the spleen, focal areas of necrosis in the liver and spleen, pericarditis, hemorrhagic fluid in the intestine, and yellowish exudate covering the brain surface are typically observed. Histopathology is found mainly in the eyes and internal organs’ capsules. Lesions on the ocular area consist of extensive fibroplasias with inflammatory cells penetration.

The epidermis contains only a single layer of cells, each of which bears multiple cilia ("hairs") and microvilli (tiny "pleats") that penetrate through the cuticle. The stolons and stalks of colonial species have thicker cuticles, stiffened with chitin. There is no coelom (internal fluid-filled cavity lined with peritoneum) and the other internal organs are embedded in connective tissue that lies between the stomach and the base of the "crown" of tentacles. The nervous system runs through the connective tissue and just below the epidermis, and is controlled by a pair of ganglia.

Posterior abdominal wall, after removal of the peritoneum, showing kidneys, suprarenal capsules, and great vessels. (Hepatic veins labeled at center top.) Any obstruction of the venous vasculature of the liver is referred to as Budd–Chiari syndrome, from the venules to the right atrium. This leads to increased portal vein and hepatic sinusoid pressures as the blood flow stagnates. The increased portal pressure causes increased filtration of vascular fluid with the formation of ascites in the abdomen and collateral venous flow through alternative veins leading to esophageal, gastric and rectal varices.
|
|
This fold is divided during lateral to medial mobilization, permitting the surgeon to serially lift the right colon and associated mesentery off the underlying fascia and retroperitoneum. At the hepatic flexure, the right lateral peritoneal fold turns and continues medially as the hepatocolic peritoneal fold. Division of the fold in this location permits separation of the colonic component of the hepatic flexure and mesocolon off the retroperitoneum. Interposed between the hepatic and splenic flexures, the greater omentum adheres to the transverse colon along a further band or fold of peritoneum.

Intraperitoneal injection or IP injection is the injection of a substance into the peritoneum (body cavity). It is more often applied to animals than to humans. In general, it is preferred when large amounts of blood replacement fluids are needed or when low blood pressure or other problems prevent the use of a suitable blood vessel for intravenous injection. In animals, it is used predominantly in veterinary medicine and animal testing for the administration of systemic drugs and fluids because of the ease of administration compared with other parenteral methods.

|
The suspensory ligament of the ovary, also infundibulopelvic ligament (commonly abbreviated IP ligament or simply IP), is a fold of peritoneum that extends out from the ovary to the wall of the pelvis. Some sources consider it a part of the broad ligament of uterus while other sources just consider it a "termination" of the ligament. It is not considered a true ligament in that it does not physically support any anatomical structures; however it is an important landmark and it houses the ovarian vessels. The suspensory ligament is directed upward over the iliac vessels.

Peptic ulcers are sores or defects that arise from tissue death, that develop in the mucosal lining of the stomach or duodenum. When a peptic ulcer bursts, the gastrointestinal or duodenal fluid leaks through it and pools in the right paracolic gutter which leads to inflammation of the peritoneum resulting in symptoms right lower quadrant of abdominal pain. Patients also develop pneumoretroperitoneum, which is air in the retroperitoneum, caused by intraperitoneal perforation in the duodenum. Untreated peptic ulcers can often lead to greater complications such as hemorrhage, obstruction, and cancer.

Studies suggest that maresins are involved in resolving inflammatory and allergic reactions, in wound healing, and in abating neuropathic pain. Mar1 enhances the uptake (i.e. stimulates the efferocytosis) of apoptotic human neutrophils by human macrophages, stimulates macrophage phagocytosis, and limits the infiltration of neutrophils into the inflamed peritoneum of mice. In a murine model of acute respiratory distress syndrome, MaR1 generation was detected in a temporally regulated manner with early MaR1 production was dependent on platelet-neutrophil interactions; intravascular MaR1 was organ-protective, leading to decreased lung neutrophils, edema, tissue hypoxia, and prophlogistic mediators.

The N stage reflects the number of metastatic lymph nodes and ranges from 0 (no lymph node metastasis) to 2 (four or more lymph node metastasis), and the M stage gives information about distant metastasis (M0 stands for no distant metastasis, and M1 for the presence of distant metastasis). A clinical classification (cTNM) is done at diagnosis and is based on MRI and CT, and a pathological TNM (pTNM) classification is performed after surgery. The most common metastasis sites for colorectal cancer are the liver, the lung and the peritoneum.

Seminal vesiculitis can cause pain in the lower abdomen, scrotum, penis or peritoneum, painful ejaculation, and blood in the semen. It is usually treated with antibiotics, although may require surgical drainage in complicated cases. Other conditions may affect the vesicles, including congenital abnormalities such as failure or incomplete formation, and, uncommonly, tumours. The seminal vesicles have been described as early as the second century AD by Galen, although the vesicles only received their name much later, as they were initially described using the term from which the word prostate is derived.

Systemic-onset juvenile idiopathic arthritis (or the juvenile onset form of Still's disease) is a type of juvenile idiopathic arthritis (JIA) with extra- articular manifestations like fever and rash apart from arthritis. It was originally called systemic-onset juvenile rheumatoid arthritis or Still's disease. Predominantly extra-articular manifestations like high fevers, rheumatic rash, enlargement of the liver and spleen, enlargement of the lymph nodes, and anemia. Others manifestations include inflammation of the pleura, inflammation of the pericardium, inflammation of the heart's muscular tissue, and inflammation of the peritoneum are also seen.

During early embryonic development, cells from the dorsal endoderm of the yolk sac migrate along the hindgut to the gonadal ridge. These primordial germ cells (PGCs) multiply by mitosis and once they have reached the gonadal ridge they are called oogonia (diploid stem cells of the ovary). Once oogonia enter this area they attempt to associate with the other somatic cells, derived from both the peritoneum and mesonephros. Development proceeds and the oogonia become fully surrounded by a layer of connective tissue cells (pre-granulosa cells) in an irregular manner.

The transversalis fascia (or transverse fascia) is a thin aponeurotic membrane which lies between the inner surface of the transverse abdominal muscle and the parietal peritoneum. It forms part of the general layer of fascia lining the abdominal parietes, and is directly continuous with the iliac fascia, internal spermatic, and pelvic fasciae. In the inguinal region, the transversalis fascia is thick and dense in structure and is joined by fibers from the aponeurosis of the transverse abdominal. It becomes thin as it ascends to the diaphragm and blends with the fascia covering the under surface of this muscle.

Maddalena Carini was born on 1 March 1917 in Pavia as the last of seven children to Giuseppe Carini and Francesca Bianchi Martina. Her father died in 1930 and her mother died in 1943. Carini began to suffer from an aggressive form of tuberculosis in 1927 in the pleura and the peritoneum and so had to spend long periods of time in a sanatorium until 1937. This ailment was known to have run through the generations. She was operated on at the age of eighteen for appendicitis coupled with peritonitis, and was treated at home until 1945 with little to no improvement.

The cranial part of the septum transversum gives rise to the central tendon of the diaphragm and is the origin of the myoblasts that invade the pleuroperitoneal folds resulting in the formation of the muscular diaphragm.Moore, N.A.; Roy, W.A.: Rapid Review Gross and Developmental Anatomy; Mosby, 2nd ed., 2006. The caudal part of the septum transversum is invaded by the hepatic diverticulum which divides within it to form the liver and thus gives rise to the ventral mesentery of the foregut, which in turn is the precursor of the lesser omentum, the visceral peritoneum of the liver and the falciform ligament.

Palliative chemotherapy, cytoreductive surgery, and radiation are also performed. Radiation therapy (VBT and EBRT) for a local vaginal recurrence has a 50% five-year survival rate. Pelvic recurrences are treated with surgery and radiation, and abdominal recurrences are treated with radiation and, if possible, chemotherapy. Other common recurrence sites are the pelvic lymph nodes, para-aortic lymph nodes, peritoneum (28% of recurrences), and lungs, though recurrences can also occur in the brain (<1%), liver (7%), adrenal glands (1%), bones (4–7%; typically the axial skeleton), lymph nodes outside the abdomen (0.4–1%), spleen, and muscle/soft tissue (2–6%).

In some postures the liver may pinch the parietal peritoneum against the lower rib cage, producing sharp, transitory pain, relieved by changing position. The tumor may also infiltrate the liver's capsule, causing dull, and sometimes stabbing pain. Kidneys and spleen :Cancer of the kidneys and spleen produces less pain than that caused by liver tumor – kidney tumors eliciting pain only once the organ has been almost totally destroyed and the cancer has invaded the surrounding tissue or adjacent pelvis. Pressure on the kidney or ureter from a tumor outside the kidney can cause extreme flank pain.

Vesalius gives detailed descriptions of the organs of nutrition, the urinary system, and the male and female reproductive systems. The alimentary and reproductive systems each make up about forty percent of this book, and the description of the renal system and the correct technique for dissecting it makes up the remainder. In the final chapter, the longest chapter of the entire collection, Vesalius gives detailed step-by-step instructions on how to dissect the abdominopelvic organs. In the first half of the book, Vesalius describes the peritoneum, the esophagus, the stomach, the omentum, the intestines and the mesentery.

The Latin anatomical name is tunica serosa. Serous membranes line and enclose several body cavities, known as serous cavities, where they secrete a lubricating fluid which reduces friction from muscle movement. Serosa is entirely different from the adventitia, a connective tissue layer which binds together structures rather than reducing friction between them. The serous membrane covering the heart and lining the mediastinum is referred to as the pericardium, the serous membrane lining the thoracic cavity and surrounding the lungs is referred to as the pleura, and that lining the abdominopelvic cavity and the viscera is referred to as the peritoneum.

The sac, which is formed from an outpouching of the peritoneum, protrudes in the midline, through the umbilicus (navel). It is normal for the intestines to protrude from the abdomen, into the umbilical cord, until about the tenth week of pregnancy, after which they return to inside the fetal abdomen. The omphalocele can be mild, with only a small loop of intestines present outside the abdomen, or severe, containing most of the abdominal organs. In severe cases surgical treatment is made more difficult because the infant's abdomen is abnormally small, having had no need to expand to accommodate the developing organs.

Thus, the green bones and some internal organs can be observed in the living animal – particularly as this species' parietal (outer) peritoneum is completely translucent, too; the inner peritonea covering the liver and gastrointestinal tract are white. The iris is greyish-white with tiny yellow dots and a network of thin, dark-grey lines; a thin cream-yellow ring surrounds the pupil. Melanophores are abundant on the dorsal surface of the fourth finger, but absent on the first three fingers. Preserved specimens are usually cream-colored to light lavender above, with the spotting remaining white or becoming transparent.

However, environmental factors and therapeutic interferences may cause some discrepancies between tumor burden and bioluminescence intensity in relation to changes in proliferative activity. The intensity of the signal measured by in vivo imaging may depend on various factors, such as D-luciferin absorption through the peritoneum, blood flow, cell membrane permeability, availability of co-factors, intracellular pH and transparency of overlying tissue, in addition to the amount of luciferase. Luciferase is a heat-sensitive protein that is used in studies on protein denaturation, testing the protective capacities of heat shock proteins. The opportunities for using luciferase continue to expand.

Most anatomical and embryological textbooks say that after adopting a final position, the ascending and descending mesocolons disappear during embryogenesis. Embryology—An Illustrated Colour Text, "most of the mid-gut retains the original dorsal mesentery, though parts of the duodenum derived from the mid- gut do not. The mesentery associated with the ascending colon and descending colon is resorbed, bringing these parts of the colon into close contact with the body wall." In The Developing Human, the author states, "the mesentery of the ascending colon fuses with the parietal peritoneum on this wall and disappears; consequently the ascending colon also becomes retroperitoneal".

|
The mesovarium is the portion of the broad ligament of the uterus that suspends the ovaries. The ovary is not covered by the mesovarium; rather, it is covered by germinal epithelium. At first the mesonephros and genital ridge are suspended by a common mesentery, but as the embryo grows the genital ridge gradually becomes pinched off from the mesonephros, with which it is at first continuous, though it still remains connected to the remnant of this body by a fold of peritoneum. In the male this is the mesorchium, and in the female, this is the mesovarium.

Due to kidney problems from her 10-year crack cocaine addiction, Matthews had to undergo peritoneal dialysis five times a day (each session was 20 minutes long). Matthews underwent a kidney transplant in 1997, but her health worsened in 2015 after she was diagnosed with sclerosing encapsulating peritonitis, an inflammatory condition of the peritoneum-a membrane which lines the inner abdomen and the abdominal organs. Matthews died in a Fremont, California, hospital on February 15, 2016, from kidney failure, aged 57.Lenker, Margaret (February 15, 2016).

The most primitive ray finned fishes retain the simple structure also found in lungfishes, but in teleosts, folds of peritoneum enclose the ovary and upper part of the tube, fusing them into a single structure. The ovary itself is hollow, with eggs being shed into the central cavity, and thence passing directly into the oviduct. The enclosed nature of the female reproductive system in these fishes makes it impossible for eggs to escape into the general body cavity; a necessary development given that thousands or even millions of eggs may be released in a single spawning.

Vomerine teeth are in two well-separated, arc-shaped rows, with eight to 10 teeth each. As with all Plethodon species, this one has four digits on the manus and five on the pes, a cylindrical tail without any basal constriction, and a tongue attached in the front. [citing Lazell (1998)] In preservative, the specimens are dark blackish-brown without any noticeable pattern, and the peritoneum lacks any distinctive pigmentation. The holotype and paratype were collected by Jackson Harold Ainsworth as Plethodon glutinosus in 1964, and described as a new species, Plethodon ainsworthi, by James Lazell in 1998.

Male and female urinary bladders in lateral cross-section In humans, the bladder is a hollow muscular organ situated at the base of the pelvis. In gross anatomy, the bladder can be divided into a broad , a body, an apex, and a neck. The apex is directed forward toward the upper part of the pubic symphysis, and from there the median umbilical ligament continues upward on the back of the anterior abdominal wall to the umbilicus. The peritoneum is carried by it from the apex on to the abdominal wall to form the middle umbilical fold.

In human female anatomy, the vesico-uterine pouch, also known by various other names, is a second but shallower pouch formed from the peritoneum over the uterus and bladder, continued over the intestinal surface and fundus of the uterus onto its vesical surface, which it covers as far as the junction of the body and cervix uteri, and then to the bladder. This pouch is an important anatomical landmark for chronic endometriosis. Endometrial seeding in this region causes cyclical pain in women of child-bearing age. This pouch is also an important factor in a retroverted uterus, which can frequently complicate pregnancies.

She also has participated in social activities, such as taking part in the Cansei movement, a 2007 protest critical of the Brazilian government. Camargo was spending New Year's Eve in Miami when she complained of severe abdominal pain. A bulletin issued by the hospital later reported that Hebe was subjected to a diagnostic laparoscopy, which found cancer.Hebe Camargo passa bem após cirurgia de três horas – Brasil em FolhasHebe Camargo está com tumor no peritônio, informa boletim médico – Brasil em Folhas On January 8, 2010, Camargo was admitted to Albert Einstein Hospital in São Paulo for surgery to remove cancer from the peritoneum.

The Massouh sign is a clinical sign for acute localised appendicitis, named after the General Surgeon Farouk Massouh from Frimley Park Hospital in Surrey/United Kingdom. The sign describes a firm swish of the examiner’s index and middle finger across the patient’s abdomen from xiphoid sternum to first the left and then the right iliac fossa. A positive Massouh sign is a grimace of the patient upon a right sided (and not left) sweep. The explanation for the reliability of this diagnostic tool is based on the fact that appendicitis in the initial stage usually causes localised irritation of the peritoneum.

The tribunal was established pursuant to the as an inferior court and a court of record. An appeal may lie to the Court of Appeal of New South Wales in certain circumstances. It has exclusive jurisdiction to deal with claims for injuries arising out of the diseases such as aluminosis, asbestosis, asbestos induced carcinoma, asbestos related pleural disease, bagassosis, berylliosis, byssinosis, coal dust pneumoconiosis, farmers’ lung, hard metal pneumoconiosis, pleural and peritoneal mesothelioma, silicosis, silico- tuberculosis and talcosis. It also has jurisdiction over any other pathological condition of the lungs, pleura or peritoneum that is attributable to dust.

"The typical CT findings are a solitary large non-enhancing omental mass with heterogeneous attenuation, which is most often located in the right lower quadrant, deep to the rectus abdominis muscle and either anterior to the transverse colon or anteromedial to the ascending colon". Omental Infarction can be difficult to differentiate from diverticulitis however omental infarction is not normally attributed with bowel wall thickening. It is rare that the colonic wall will be thickened due to spread of the inflammation from the omentum (a fold of peritoneum connecting or supporting abdominal structures) to the tenia omentalis of the colon. Diverticulitis: Diverticulitis normally happens in older patients than in epiploic appendagitis.

The supravaginal portion of the cervix (also known as the uterine portion of the cervix) is separated in front from the bladder by fibrous tissue (parametrium), which extends also on to its sides and lateralward between the layers of the broad ligaments. The uterine arteries reach the margins of the cervix in this fibrous tissue, while on either side the ureter runs downward and forward in it at a distance of about 2 cm. from the cervix. Posteriorly, the supravaginal cervix is covered by peritoneum, which is prolonged below on to the posterior vaginal wall, when it is reflected on to the rectum, forming the recto-uterine pouch.

In advanced cancers, where complete removal is not an option, as much tumor as possible is removed in a procedure called debulking surgery. This surgery is not always successful, and is less likely to be successful in women with extensive metastases in the peritoneum, stage- IV disease, cancer in the transverse fissure of the liver, mesentery, or diaphragm, and large areas of ascites. Debulking surgery is usually only done once. Computed tomography (abdominal CT) is often used to assess if primary debulking surgery is possible, but low certainty evidence also suggests fluorodeoxyglucose‐18 (FDG) PET/CT and MRI may be useful as an addition for assessing macroscopic incomplete debulking.

Mayer described the possible ovary as having a texture more similar to an ovary than to a testicle and stated that the structure, which was covered by the peritoneum, "consisted only of granulations and lumps of fat". Mayer's final diagnosis confirmed Derrier's hermaphroditism, concluding that there were stronger female characteristics. Derrier's life is illustrative of how persons presumed to be women at birth but later found to have atypical genital morphology were able to gain greater autonomy through legal codes which allowed them to claim rights as men. Observation of Derrier and other intersex people who traveled allowed an emergence of comparative serial analysis, which had previously not occurred in medicine.

The tunica vaginalis is the pouch of serous membrane that covers the testes. It is derived from the vaginal process of the peritoneum, which in the fetus precedes the descent of the testes from the abdomen into the scrotum. After its descent, that portion of the pouch which extends from the abdominal inguinal ring to near the upper part of the gland becomes obliterated; the lower portion remains as a shut sac, which invests the surface of each testis, and is reflected on to the internal surface of the scrotum; hence it may be described as consisting of a visceral and a parietal lamina.

Also, in the inguinal crest a structure, the gubernaculum testis, makes its appearance. This is at first a slender band, extending from that part of the skin of the groin which afterward forms the scrotum through the inguinal canal to the body and epididymis of the testis. As development advances, the peritoneum enclosing the gubernaculum forms two folds, one above the testis and the other below it. The one above the testis is the plica vascularis, and contains the upper part of the gubernaculum, and ultimately also the internal spermatic vessels; the one below, the plica gubernatrix, contains the lower part of the gubernaculum.

PD is less efficient at removing wastes from the body than hemodialysis, and the presence of the tube presents a risk of peritonitis due to the potential to introduce bacteria to the abdomen. There is not sufficient evidence to be clear about the best treatment for PD-associated peritonitis, although direct infusion of antibiotics into the peritoneum appears to offer slight advantage over the intravenous route of administration; there is no clear advantage for other frequently used treatments such as routine peritoneal lavage or use of urokinase. The use of preventative nasal mupirocin is of unclear effect with respect to peritonitis. Infections can be as frequent as once every 15 months (0.8 episodes per patient year).

The greater omentum (also the great omentum, omentum majus, gastrocolic omentum, epiploon, or, especially in animals, caul) is a large apron-like fold of visceral peritoneum that hangs down from the stomach. It extends from the greater curvature of the stomach, passing in front of the small intestines and doubles back to ascend to the transverse colon before reaching to the posterior abdominal wall. The greater omentum is larger than the lesser omentum, which hangs down from the liver to the lesser curvature. The common anatomical term "epiploic" derives from "epiploon", from the Greek epipleein, meaning to float or sail on, since the greater omentum appears to float on the surface of the intestines.

On Tuesday 3 April 1888, following the Easter Monday bank holiday, 45-year-old prostitute Emma Elizabeth Smith was assaulted and robbed at the junction of Osborn Street and Brick Lane, Whitechapel, in the early hours of the morning. Although injured, she survived the attack and managed to walk back to her lodging house at 18 George Street, Spitalfields. She told the deputy keeper, Mary Russell, that she had been attacked by two or three men, one of them a teenager. Mrs Russell took Smith to the London Hospital, where a medical examination revealed that a blunt object had been inserted into her vagina, rupturing her peritoneum. She developed peritonitis and died at 9 am the following day.

In postmenopausal women, and in those who have fulfilled their reproductive wishes, the following standardised procedures will be carried out: a thorough exploration of the abdominal cavity, bilateral salpingo-oophorectomy, total hysterectomy, inframesocolic omentectomy, peritoneal lavage to obtain samples for cytology, resection of macroscopically suspicious lesions, and multiple peritoneal biopsies (including omentum, intestinal serosa, mesentery, pelvic, and abdominal peritoneum), although this practice is in disuse due to its low sensitivity and the apparent lack of utility of randomised biopsies where no suspicious lesions are present. In addition, in cases of mucinous BOT, appendectomies are performed to exclude ovarian metastasis whose origin is a primary carcinoma of the appendix. Table 1. Factors for bad BOT prognosis.

In 1942, Merrill Chase discovered that cells taken from the peritoneum of Guinea pigs that had been immunized against an antigen could transfer immunity when injected into Guinea pigs that had never been exposed to the antigen; this phenomenon was the discovery of cell-mediated immunity. Subsequent research attempted to uncover how the cells imparted their effects. Henry Sherwood Lawrence, in 1955, discovered that partial immunity could be transferred even when the immune cells had undergone lysis - indicating that cells did not need to be fully intact in order to produce immune effects. Lawrence went on to discover that only the factors less than 8000 Daltons were required to transfer this immunity; he termed these to be "transfer factors".

The intercostal nerves are part of the somatic nervous system, and arise from the anterior rami of the thoracic spinal nerves from T1 to T11. The intercostal nerves are distributed chiefly to the thoracic pleura and abdominal peritoneum and differ from the anterior rami of the other spinal nerves in that each pursues an independent course without plexus formation. The first two nerves supply fibers to the upper limb in addition to their thoracic branches; the next four are limited in their distribution to the walls of the thorax; the lower five supply the walls of the thorax and abdomen. The 7th intercostal nerve terminates at the xyphoid process, at the lower end of the sternum.

The mesentery is an organ that attaches the intestines to the posterior abdominal wall in humans and is formed by the double fold of peritoneum. It helps in storing fat and allowing blood vessels, lymphatics, and nerves to supply the intestines, among other functions. The mesocolon was thought to be a fragmented structure, with all named parts—the ascending, transverse, descending, and sigmoid mesocolons, the mesoappendix, and the mesorectum—separately terminating their insertion into the posterior abdominal wall. However, in 2012, new microscopic and electron microscopic examinations at the University of Limerick showed the mesocolon to be a single structure derived from the duodenojejunal flexure and extending to the distal mesorectal layer.

In the pelvic cavity this vessel is in relation, laterally, with the obturator fascia; medially, with the ureter, ductus deferens, and peritoneum; while a little below it is the obturator nerve. Inside the pelvis the obturator artery gives off iliac branches to the iliac fossa, which supply the bone and the Iliacus, and anastomose with the ilio-lumbar artery; a vesical branch, which runs backward to supply the bladder; and a pubic branch, which is given off from the vessel just before it leaves the pelvic cavity. The pubic branch ascends upon the back of the pubis, communicating with the corresponding vessel of the opposite side, and with the inferior epigastric artery.

May Owen (May 3, 1891 – April 12, 1988) was a Texas physician who discovered that the talcum powder used on surgical gloves caused infection and scar tissue to form on the peritoneum. She was the first woman elected as president of the Texas Society of Pathologists (1945), of the Tarrant County Medical Society (1947), and of the Texas Medical Association (1960). She endowed the second chair of the Texas Tech University School of Medicine and received many awards during her career, including induction into the Texas Women's Hall of Fame, Recognition of Merit from the Texas Medical Association, and receipt of the George T. Caldwell Award from the Texas Society of Pathologists.

It is almost completely invested by peritoneum, and is connected to the inferior border of the pancreas by a large and wide duplicature of that membrane, the transverse mesocolon. It is in relation, by its upper surface, with the liver and gall-bladder, the greater curvature of the stomach, and the lower end of the spleen; by its under surface, with the small intestine; by its anterior surface, with the posterior layer of the greater omentum and the abdominal wall; its posterior surface is in relation from right to left with the descending portion of the duodenum, the head of the pancreas, and some of the convolutions of the jejunum and ileum. The transverse colon absorbs water and salts.

The left colic artery is a branch of the inferior mesenteric artery that runs to the left behind the peritoneum and in front of the psoas major muscle, and after a short, but variable, course divides into an ascending and a descending branch; the stem of the artery or its branches cross the left ureter and left internal spermatic vessels. The ascending branch crosses in front of the left kidney and ends, between the two layers of the transverse mesocolon, by anastomosing with the middle colic artery; the descending branch anastomoses with the highest sigmoid artery. From the arches formed by these anastomoses branches are distributed to the descending colon and the left part of the transverse colon.

A potentially fatal complication estimated to occur in roughly 2.5% of patients is encapsulating peritoneal sclerosis, in which the bowels become obstructed due to the growth of a thick layer of fibrin within the peritoneum. The fluid used for dialysis uses glucose as a primary osmotic agent, but this may lead to peritonitis, the decline of kidney and peritoneal membrane function and other negative health outcomes. The acidity, high concentration and presence of lactate and products of the degradation of glucose in the solution (particularly the latter) may contribute to these health issues. Solutions that are neutral, use bicarbonate instead of lactate and have few glucose degradation products may offer more health benefits though this has not yet been studied.

Compared to CAOV-3 human ovarian cancer cells, SKOV-3 and CAOV-3 human ovarian cancer cells over express BLT4 receptors, LTB4 and 12-HETE metabolizing enzymes, two key metabolites of these enzymes, LTB4 and 12-HETE, and activated STAT3 also are far more invasive in animal models. Inhibition of BLT2 receptors by LY255283 but not of BLT1 receptors by U75302 and suppression of BLT2 receptors by siRNA treatment reduced the expression of NOX4 (i.e. NADPH oxidase 4, the reactive oxygen species made by this enzyme, activated STAT3, the invasion- promoting enzyme, MMP 2, and the in vitro invasiveness (Matrigel invasion assay) of SKOV-3 and CAOV-3 cells. LY255283 also inhibited the peritoneum metastasis of intra-peritoneal injected SKOV-3 cells in athymic mice.

Before writing The Mission Walker, Edie Littlefield Sundby was a corporate executive, entrepreneur, and mother. In March 2007, Edie was diagnosed with stage-4 adenocarcinoma of the gallbladder with widespread metastasis, including liver, colon, peritoneum, and groin - and given a few months to live. While undergoing aggressive cancer treatment, she shared her reflections on life and illness, authoring essays in The New York Times and The Wall Street Journal. Over the course of six years she endured 79 rounds of chemotherapy, multiple radical surgeries (including the removal of her right lung, half her liver, and part of her colon and stomach), and intense radiation; through it all she walked, and, in The New York Times, she credits walking with saving her life.

Delarue died at the age of 48 on the 23 August 2012 from cancer of the stomach and peritoneum, having been hospitalised due to his deteriorating health. He had revealed he was suffering from cancer during a press conference held at the headquarters of France Télévisions on the 2 December 2011, pre-empting a member of the paparazzi who had gained possession of his medical records. A frail looking Delarue made a final public appearance at a Fashion Week in January 2012, with his partner by his side. On the 22 July 2012, a month before his death, Delarue was the victim of a hoax: a false rumour that he had died circulated, having been started on the social network site Twitter.

Some identical twins—known as mirror image twins—can have a mirror-imaged anatomy, a congenital condition with the appendix located in the lower left quadrant of the abdomen. Intestinal malrotation may also cause displacement of the appendix to the left side. While the base of the appendix is typically located 2 cm below the ileocecal valve, the tip of the appendix can be variably located—in the pelvis, outside the peritoneum or behind the cecum. The prevalence of the different positions varies amongst populations with the retrocecal position being most common in Ghana and Sudan, with 67.3% and 58.3% occurrence respectively, in comparison to Iran and Bosnia where the pelvic position is most common, with 55.8% and 57.7% occurrence respectively.

This is likely because the cells that give rise to endometriosis are a side population of cells. Similarly, there are changes in for example the mesothelium of the peritoneum in women with endometriosis, such as loss of tight junctions, but it is unknown if these are causes or effects of the disorder. In rare cases where imperforate hymen does not resolve itself prior to the first menstrual cycle and goes undetected, blood and endometrium are trapped within the uterus of the woman until such time as the problem is resolved by surgical incision. Many health care practitioners never encounter this defect, and due to the flu-like symptoms it is often misdiagnosed or overlooked until multiple menstrual cycles have passed.

Such theories include diaphragmatic ischemia, imbalances of the thoracic spine, irritation of the parietal peritoneum and strain on visceral ligaments by a fluid-engorged gut. A further theory points to shallow breathing as a possible cause for a stitch and one possible preventative measure involves adjusting at what point in a runner's stride they inhale, or reducing the frequency of inhales (with an increase in inspiratory capacity).p 391 The Lore of Running, Tim Noakes, Publisher: Human Kinetics Publishers Date Published: 1991 The reasons for the variety of theories include, in particular, the prevalence of ETAP during swimming. There is also a belief that an imbalance of electrolytes (such as calcium, potassium, and sodium) in the blood could also contribute to the side stitch.

Infection of the peritoneum causes an inflammatory reaction with a subsequent increase in the number of neutrophils in the fluid. Diagnosis is made by paracentesis (needle aspiration of the ascitic fluid); SBP is diagnosed if the fluid contains neutrophils (a type of white blood cell) at greater than 250 cells per mm3 (equals a cell count of 250 x106/L) fluid in the absence of another reason for this (such as inflammation of one of the internal organs or a perforation). The fluid is also cultured to identify bacteria. If the sample is sent in a plain sterile container 40% of samples will identify an organism, while if the sample is sent in a bottle with culture medium, the sensitivity increases to 72–90%.

The right colic artery arises from about the middle of the concavity of the superior mesenteric artery, or from a stem common to it and the ileocolic. It passes to the right behind the peritoneum, and in front of the right internal spermatic or ovarian vessels, the right ureter and the Psoas major, toward the middle of the ascending colon; sometimes the vessel lies at a higher level, and crosses the descending part of the duodenum and the lower end of the right kidney. At the colon it divides into a descending branch, which anastomoses with the ileocolic, and an ascending branch, which anastomoses with the middle colic. These branches form arches, from the convexity of which vessels are distributed to the ascending colon.

Just as in the male, there is a gubernaculum in the female, which effects a considerable change in the position of the ovary, though not so extensive a change as in that of the testis. The gubernaculum in the female lies in contact with the fundus of the uterus and adheres to this organ, and thus the ovary can only descend as far as to this level. The part of the gubernaculum between the ovary and the uterus ultimately becomes the proper ovarian ligament, while the part between the uterus and the labium majus forms the round ligament of the uterus. A pouch of peritoneum analogous to the vaginal process in the male accompanies it along the inguinal canal: it is called the canal of Nuck.

A large double fold of visceral peritoneum called the greater omentum hangs down from the greater curvature of the stomach. Two sphincters keep the contents of the stomach contained; the lower oesophageal sphincter (found in the cardiac region), at the junction of the oesophagus and stomach, and the pyloric sphincter at the junction of the stomach with the duodenum. The stomach is surrounded by parasympathetic (stimulant) and sympathetic (inhibitor) plexuses (networks of blood vessels and nerves in the anterior gastric, posterior, superior and inferior, celiac and myenteric), which regulate both the secretory activity of the stomach and the motor (motion) activity of its muscles. Because it is a distensible organ, it normally expands to hold about one litre of food.

A physical examination, including a pelvic examination, and a pelvic ultrasound (transvaginal or otherwise) are both essential for diagnosis: physical examination may reveal increased abdominal girth and/or ascites (fluid within the abdominal cavity), while pelvic examination may reveal an ovarian or abdominal mass. An adnexal mass is a significant finding that often indicates ovarian cancer, especially if it is fixed, nodular, irregular, solid, and/or bilateral. 13–21% of adnexal masses are caused by malignancy; however, there are other benign causes of adnexal masses, including ovarian follicular cyst, leiomyoma, endometriosis, ectopic pregnancy, hydrosalpinx, tuboovarian abscess, ovarian torsion, dermoid cyst, cystadenoma (serous or mucinous), diverticular or appendiceal abscess, nerve sheath tumor, pelvic kidney, ureteral or bladder diverticulum, benign cystic mesothelioma of the peritoneum, peritoneal tuberculosis, or paraovarian cyst. Ovaries that can be felt are also a sign of ovarian cancer in postmenopausal women.

Studies find that the maresins inhibit certain pro-inflammatory functions in human neutrophils and macrophages in vitro, that MaR1 and Mar2 reduce the entry of blood neutrophils into the inflamed peritoneum in a mouse model, and that Mar1 promotes the resolution of allergic pulmonary inflammation in a mouse model as well as wound healing in planaria worm model. These studies have not yet translated to human physiology or pathology. It is noted that MaR1 is detectable in the synovial fluid of patients with rheumatoid arthritis. It is also noted that macrophages derived by culturing the monocytes isolated from the blood of patients with Localized aggressive periodontitis have reduced levels of 12-lipoxygenase and MaR1 as well as reduced phagocytosis and killing of the periodontal pathogenic bacteria, Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans; the latter functional defects were improved by treating the cells with MaR1.

The primitive mesentery of a six weeks’ human embryo, half schematic. (Lesser omentum labeled at left.) Schematic and enlarged cross-section through the body of a human embryo in the region of the mesogastrium, at end of third month The lesser omentum is extremely thin, and is continuous with the two layers of peritoneum which cover respectively the antero-superior and postero-inferior surfaces of the stomach and first part of the duodenum. When these two layers reach the lesser curvature of the stomach and the upper border of the duodenum, they join together and ascend as a double fold to the porta hepatis. To the left of the porta, the fold is attached to the bottom of the fossa for the ductus venosus, along which it is carried to the diaphragm, where the two layers separate to embrace the end of the esophagus.

In the anatomy of humans and homologous primates, the ascending colon is the part of the colon located between the cecum and the transverse colon. The ascending colon is smaller in calibre than the cecum from where it starts. It passes upward, opposite the colic valve, to the under surface of the right lobe of the liver, on the right of the gall-bladder, where it is lodged in a shallow depression, the colic impression; here it bends abruptly forward and to the left, forming the right colic flexure (hepatic) where it becomes the transverse colon. It is retained in contact with the posterior wall of the abdomen by the peritoneum, which covers its anterior surface and sides, its posterior surface being connected by loose areolar tissue with the iliacus, quadratus lumborum, aponeurotic origin of transversus abdominis, and with the front of the lower and lateral part of the right kidney.

They are two slender vessels of considerable length, and arise from the front of the aorta a little below the renal arteries. Each passes obliquely downward and lateralward behind the peritoneum, resting on the Psoas major, the right lying in front of the inferior vena cava and behind the middle colic and ileocolic arteries and the terminal part of the ileum, the left behind the left colic and sigmoid arteries and the iliac colon. Each crosses obliquely over the ureter and the lower part of the external iliac artery to reach the abdominal inguinal ring, through which it passes, and accompanies the other constituents of the spermatic cord along the inguinal canal to the scrotum, where it becomes tortuous, and divides into several branches. Two or three of these accompany the ductus deferens, and supply the epididymis, anastomosing with the artery of the ductus deferens; others pierce the back part of the tunica albuginea, and supply the substance of the testis.

As the testes develops, the main portion of the lower end of the gubernaculum is carried, following the skin to which it is attached, to the bottom of this pouch. Other bands are carried to the medial side of the thigh and to the perineum. The tube of peritoneum constituting the vaginal process projects itself downward into the inguinal canal, and emerges at the external inguinal ring, pushing before it a part of the obliquus internus and the aponeurosis of the obliquus externus, which form respectively the cremaster muscle and the external spermatic fascia. The vaginal process forms a gradually elongating pouch, which eventually reaches the bottom of the scrotum, and behind this pouch the testis is drawn by the growth of the body of the fetus, for the gubernaculum does not grow proportionately with the growth of other parts, and therefore the testis, being attached by the gubernaculum to the bottom of the scrotum, is prevented from rising as the body grows, and is instead drawn first into the inguinal canal and eventually into the scrotum.
