Dicyema, a small parasite typically described as "vermiform" Vermiform describes something shaped like a worm. The expression is often employed in biology and anatomy to describe usually soft body parts or animals that are more or less tubular or cylindrical. The word root is Latin, vermes (worms) and formes (shaped). A well known example is the vermiform appendix, a small, blind section of the gut in humans and a number of other mammals.

Vermiform Records was an American independent record label that specialized in releasing punk rock music from 1990 until 2002. Vermiform released 58 albums and relocated many times, being headquartered in New York, New Jersey, Virginia, Rhode Island and California at different times. The label was run by Sam McPheeters, the singer from the band Born Against.

Three more molts occur, J2 becomes J3, J4 and then adult. M. incognita is sexually dimorphic. Females acquire a globose shaped body while males become vermiform and leave the roots.
|
|
The color their coats changes each season. It is black with many vermiform (worm-like structures) during the winter. In the summer the coat lighter and lacks the worm-like structures.

The merozoites become free by dropping off the parent trophozoite. Gamonts, gametocysts and oocysts are of the actinocephalid type with syzygy occurring just before gametocyst formation. The young gamonts are vermiform (wormlike). The gametocysts are mostly spherical.
|
|
The solitary lymphatic nodules of the large intestine are most abundant in the cecum and vermiform process, but are irregularly scattered also over the rest of the intestine. They are similar to those of the small intestine.

The female alfalfa cyst nematode is white and shaped like a lemon with a body length of 0.4 to 1.2 mm and a width of 0.2 to 0.9 mm. The male is vermiform with a body length of 1.2 to 1.4 mm and a width of about 0.028 mm. The eggs are reniform, measuring 0.12 by 0.05 mm and the first two instar larvae are vermiform. The second instar larvae are mobile in damp soil and search down to a depth of 30 centimetres for suitable roots to invade.

The Vermiform tells Jant that Cyan has entered the Shift and together they rescue her from the Gabbleratchet, a strange monster which constantly shifts between worlds in a bizarre hunt. On the run from the creature, the Vermiform shows them many worlds which have fallen to the Insects. When they escape back to the real world, Cyan reluctantly agrees to join her father at Slake Cross. On his flight back to the dam, Jant is shocked to feel the Circle break three times, each indicating the death of an immortal.

The Malayan is a butterfly of evergreen forests. Its caterpillar is light green, vermiform, the middle segments swollen; it feeds on Allophyllus cobbe (Sapindaceae). The pupa is thick, with blunted ends.Haribal (1992) Adults fly low, close to the ground.
|
|
The trophozoites are found in the intestinal lumen. They measure 23-31 microns x 11-15 microns. They are initially ovoid and become vermiform as they mature. The single nucleus lies at the anterior end and has one nucleolus.
|
|
The larvae which hatch from the eggs are vermiform maggots, similar to other fruit flies. They possess an elongated and cylindrical shape. These larvae progress through 3 instars, or stages between molting. First instar larvae appear clear to pale white.

The environment is interpreted as sand bars formed at the mouth of a delta's distributaries. Mattress-like vendobionts (Ernietta, Pteridinium, Rangea) in these sandstones form a very different assemblage from vermiform fossils (Cloudina, Namacalathus) of Ediacaran "wormworld" in marine dolomite of Namibia.
|
|
Dicyemids exist in both asexual and sexual forms. The former predominate in juvenile and immature hosts, and the latter in mature hosts. The asexual stage is termed a nematogen; it produces vermiform larvae within the axial cell. These mature through direct development to form more nematogens.

Adults and juveniles are vermiform in shape. Adults are sexually dimorphic. The male has a poorly developed stylet, a knob-like head, and a sharp, curved spicule enclosed in a sac. The male is 500 to 600 µm in length, while the female is about 550 to 880 µm long.
|
|
In very rare cases, the appendix may not be present at all (laparotomies for suspected appendicitis have given a frequency of 1 in 100,000). Sometimes there is a semi-circular fold of mucous membrane at the opening of the appendix. This valve of the vermiform appendix is also called Gerlach's valve.

|
This will prevent the established plants from getting infected from a new, infected plant. All symptomatic plants should be destroyed immediately. Dead plant material should also be handled with caution. Vermiform nematodes can survive and reproduce in compost piles of dead plant material by feeding on fungi that are commonly found in compost.

The eponymous "Gerlach's valve" (valvula processus vermiformis) is named after him. This anatomical structure is a fold of membrane sometimes found at the opening of the vermiform appendix.Mondofacto Dictionary Gerlach's valve In his article Ueber das Hautathmenvon Gerlach, J. (1851): Ueber das Hautathmen. In: Archiv für Anatomie, Physiologie und wissenschaftliche Medicin. pp.

The zygote remains inactive for sometime but it soon elongates, becomes vermiform (worm-like) and motile. It is now known as ookinete. The pointed ends of ookinete penetrate the stomach wall and come to lie below its outer epithelial layer. Here the zygote becomes spherical and develops a cyst wall around itself.
|
|
Once this site is established, the nematode is no longer moving. The feeding J2s then molt 2 more times into third- and fourth-stage juveniles and grow as they are feeding. The last molt reveals the adult stages. Males of H. sacchari are rarely found, but return to vermiform (worm shape) and exit the root.

|
The ascus tip possesses a thick, double-apical ring and lacks a sub-apical globulus. Paraphyses, erect filament-like structures, appear longer than asci. The ascospores contained within the asci are arranged in series of 2-3. In immature asci, the spores are initially hyaline (colourless), single-celled, cylindrical, vermiform (worm-like), slightly sigmoid, and smooth.

The band toured the US extensively, and also made two trips to Japan. Men's Recovery Project released four full-length albums and numerous smaller releases on labels such as Kill Rock Stars, Lungcast Records and McPheeters' own Vermiform Records. Following their demise, McPheeters formed the short-lived hardcore band Wrangler Brutes. Burke is involved in art and screen-printing.

Ingolfiellidea is a small suborder of amphipods with only two families, Ingolfiellidae and Metaingolfiellidae. They are small, vermiform (worm-like) animals that live "in the soft mud of the deep-sea floor, as well as in high mountain freshwater river beds, or in subterranean fresh, brackish and marine interstitial waters of continental ground waters and continental shelves".

At the broadest level, their body is divided into head, trunk, and tail, although the divisions are not always externally visible. The body is often fusiform, a streamlined body plan often found in fast-moving fish. They may also be filiform (eel-shaped) or vermiform (worm- shaped). Fish are often either compressed (laterally thin) or depressed (dorso-ventrally flat).

Climacostomum virens The body is somewhat flexible but non-contractile, roughly ovoid or harp- shaped, and flattened from back to front. It has a large posterior contractile vacuole, and a characteristic posterior indentation (more pronounced in underfed individuals). The posterior vacuole surrounds the cytoproct (anus), through which food waste is eliminated. The macronucleus of Climacostomum virens is normally long and wormlike (vermiform).

De Garengeot's hernia is a rare subtype of an incarcerated femoral hernia. This eponym may be used to describe the incarceration of the vermiform appendix within a femoral hernia. Akopian and Alexander, named this hernia after the 18th century Parisian surgeon Rene Jacques Croissant de Garengeot. He is quoted in the surgical literature as the first to describe this situation in 1731.

Early in their career, the (Young) Pioneers moved from McPheeters' Vermiform Records to the larger Lookout! Records label, where they released several records before disbanding in 1999. During this era, Nathanson also briefly played in the post-Born Against group Men's Recovery Project. Nathanson most recently formed Teargas Rock, a sporadically active group continuing in the direction of (Young) Pioneers.

Dark brown band runs from the side of head to the dorsal half of flank. The posterior surface of forearm, ventral half of flank, anterior and posterior surface of thigh, posterior surface of shank, and dorsal surface of foot are black with distinct, vermiform, bright yellow markings. The upper lip stripe is yellow while the lower lip is black. The belly is white.

As their name suggests they are basically mucus lined cysts and they can also occur in the paranasal sinuses, most commonly the frontal sinuses, the frontoethmoidal region and also in the maxillary sinus. Sphenoid sinus involvement is extremely rare. When the lumen of the vermiform appendix of the intestine gets blocked due to any factor, a mucocele can also form there.

Movement of wild-type C. elegans C. elegans is unsegmented, vermiform, and bilaterally symmetrical. It has a cuticle (a tough outer covering, as an exoskeleton), four main epidermal cords, and a fluid- filled pseudocoelom (body cavity). It also has some of the same organ systems as larger animals. About one in a thousand individuals is male and the rest are hermaphrodites.

Clinical exam may reveal sectoral paresis of the iris sphincter or vermiform iris movements. The tonic pupil may become smaller (miotic) over time which is referred to as "little old Adie's". Testing with low dose (1/8%) pilocarpine may constrict the tonic pupil due to cholinergic denervation supersensitivity. A normal pupil will not constrict with the dilute dose of pilocarpine.

She tells them that the mission has been accomplished, that Owen must stay inside due to being infected, and that the only survivor allowed to leave is Ángela. A flashback then reveals what happened right before the story's beginning: Ángela was captured by Medeiros and had a vermiform organism orally transmitted into her. As the response team arrived, Ángela went into hiding.

All the songs deal with issues involving personal relationships and all but the first relate to relationship problems. The E.P. was released shortly after Bark Like A Dog on Vermiform Records (later reissue on Lookout! Records and Weasel's own imprint, Panic Button). It is now out of print, but the songs are available as bonus tracks on the album Beat Is on the Brat.

A number of soft-bodied animal phyla are typically described as vermiform. The better- known ones are undoubtedly the annelids (earthworm and relatives) and the roundworms (a very common, mainly parasitic group), but a number of less well- known phyla answer to the same description. Examples range from the minute parasitic mesozoans to the larger-bodied free-living phyla like ribbon worms, peanut worms, and priapulids.

Nematopsis was first described by A. Schneider in France in 1892 (Schneider 1892). Due to N. portunidarum’s (previously known as N. schneideri) ovoid oocysts, Schneider initially assigned the species to the Coccidia (Solter et al. 2012). However, in 1903 Leger found similar spores in mussels and proposed the name Nematopsis schneider. These spores germinated into vermiform sporozoites resembling small nematode worms, hence the name Nematopsis.

The tadpoles of Leptobrachella mjobergi are relatively small (total length up to ) and have a vermiform or eel-like appearance. The transition from the narrow, cylindrical trunk into the strong tail is nearly seamless, and the tail fin is very low. They have unusually mobile head and trunk. While smaller tadpoles seem to use existing interstitial spaces, larger ones can actively push their way through gravel.

Leptobrachella are small frogs that are not easily seen as they are well camouflaged on the ground. However, their advertisement call is loud, and they can be abundant along streams. The tadpoles of Leptobrachella are unusual in their vermiform or eel-like appearance. The transition from the narrow, cylindrical trunk into the strong tail is nearly seamless, and the tail fin is very low.

Sometimes the tubular form collapses near the distal end, most likely when the pressure of escaping gases decreased and still-molten portions of the stalactites deflated and cooled. Often these tubular stalactites will acquire a twisted, vermiform appearance as bits of lava crystallize and force the flow in different directions. These tubular lava helictites may also be influenced by air currents through a tube and point downwind.

Dicyema shimantoense is a parasitic worm of the Phylum Dicyemida. It is a vermiform mesozoan parasite that infects the renal appendages of the cephalopod Octopus sasakii. The name is derived from the Shimanto River, which is the longest river in Shikoku, and flows into Tosa Bay. A study from 2000-06 used 59 specimens obtained from fishermen at Tosa Bay and Kii Strait Japan.

The Descent of Man, and Selection in Relation to Sex. John Murray: London. Some herbivorous animals, such as rabbits, have a terminal vermiform appendix and cecum that apparently bear patches of tissue with immune functions and may also be important in maintaining the composition of intestinal flora. It does not however seem to have much digestive function, if any, and is not present in all herbivores, even those with large caeca.

Paratylenchus hamatus is a migratory endoparasite which means it retains its vermiform shape during its adult life. Because of their close association with host root systems, pin nematodes are easily spread from field to field through the transportation of already infected soil and plant parts. Paratylenchus spp. females generally lay eggs one at a time and can lay up to 4 eggs per day when feeding on host tissue.

Inside the gametocytes are many gymnospores and membranous sacs. The gymnospores are composed of many radially arranged, cone-shaped sporozoites, the infective agent that infects a target host (Galinski and Barnwell 2012). At the sporozoite rostral end there is an oval nucleus, rough endoplasmic reticulum, mitochondria and secretory granules (Tuntuwaranuruk et al. 2015). The oocyst of Nematopsis contains a single uni-nucleated vermiform sporozoite (Prasadan and Janardana 2001).

In addition to playing on many of its recordings, Burke did extensive graphic design work for Sam McPheeters' Vermiform Records and helped create the label's distinct look. His work with Monoroid, the design and printing company he runs, continues in this stylistic direction. Neil has designed many album covers aside from Men's Recovery Project and Sinking Body. Some bands include Hail Mary, Amps for Christ and The Locust.

The nucleus is subcentral, but approaches the basal and columellar margins. The external surface is porcelain-white, very thick near the left upper part, less so on the right side. It is covered with not very conspicuous, somewhat vermiform rugosities, and has a marked depression on the lower half, slightly to the left, nearly opposite to the nucleus on the internal side. The right margin is smooth and shining.

Spironema multiciliatum Spironemidae is a family of heterotrophic flagellates, in the group Hemimastigophora. They vary in size and shape from the ellipsoid Hemimastix amphikineta (14 × 7 μm) to the vermiform Spironema terricola (43 × 3 μm), and are united by the possession of two rows of cilia, called kineties. Phylogenomic analysis shows that Hemimastigophora are a distinct and ancient lineage of eukaryotic organisms, forming a possible sister clade to the supergroup Diaphoretickes.

The yellow eggs are deposited in a hollow, cylindrical, jellylike mass in the burrow. Adults can pass through the centre of this. The outer side of the mass is coated in debris while the inner side is clean. When the larvae hatch, they pass through a number of ciliated, spherical and hemispherical developmental stages before becoming vermiform juveniles and developing the proboscis, collar and trunk of the adult.

Rhombozoa, or dicyemid mesozoans, are found in the nephrid tracts of squid and octopuses. They range from a few millimeters long with twenty to thirty cells that include anterior attachment cells and a long central reproductive cell called an axial cell. This axial cell may develop asexually into vermiform juveniles or it may produce eggs and sperm that self-fertilize to produce a ciliated infusiform larva. There are three genera: Dicyema, Pseudicyema and Dicyemennea.

Climacostomum virens, from Alfred Kahl, 1932 Climacostomum virens has a flexible but non-contractile body, long, roughly ovoid or harp- shaped, and flattened from back to front. It has a large posterior contractile vacuole, and a characteristic posterior indentation, or dimple, that is more pronounced in underfed individuals. The posterior vacuole surrounds the cytoproct (anus), through which food waste is eliminated. The macronucleus of Climacostomum virens is normally long and wormlike (vermiform).

Nematogens proliferate in young cephalopods, filling the kidneys. As the infection ages, perhaps as the nematogens reach a certain density, vermiform larvae mature to form rhombogens, the sexual life stage, rather than more nematogens. This sort of density-responsive reproductive cycle is reminiscent of the asexual reproduction of sporocysts or rediae in larval trematode infections of snails. As with the trematode asexual stages, a few nematogens can usually be found in older hosts.
|
|
The life cycle is around 24–28 days with optimum temperature being 25-30 C (Huang and Becker, 1999 & Robbins and Barker, 1974). The nematode survives extremes in temperature or drought by moving deeper into the soil (Robbins and Barker, 1974). All vermiform life stages feed on roots and feeding is required to mate and reproduce. Females must be fertilized by a male for viable eggs to be produced (Huang and Becker, 1999).

10x magnification photo of Adult hermaphroditic female Parasitic nematode (Phasmarhabditis hermaphrodita). 1 Eye Piece Unit = 9.5μm P. hermaphrodita is unsegmented, vermiform, bilateral symmetrical pseudocoelomate. The body dimensions and structure of P. hermaphrodita is comparable to C. elegans' with a body length 1.3 - 1.7 mm long and an estimated circumference of 0.180mm. The primary structures are the Rhabditida-specific mouth, the pharynx, the intestine, the reproductive system (uterus, spermatheca, gonads) and the cuticle.

Gulf fritillary life cycle, an example of holometabolism. Holometabolism, or complete metamorphosis, is where the insect changes in four stages, an egg or embryo, a larva, a pupa and the adult or imago. In these species, an egg hatches to produce a larva, which is generally worm-like in form. This worm-like form can be one of several varieties: eruciform (caterpillar-like), scarabaeiform (grub-like), campodeiform (elongated, flattened and active), elateriform (wireworm-like) or vermiform (maggot-like).

A scanning electron micrograph of the mouthparts of A. simplex Anisakis share the common features of all nematodes: the vermiform body plan, round in cross section, and a lack of segmentation. The body cavity is reduced to a narrow pseudocoel. The mouth is located anteriorly and surrounded by projections used in feeding and sensation, with the anus slightly offset from the posterior. The squamous epithelium secretes a layered cuticle to protect the body from digestive acids.

A mature male's cloaca extends beyond the carapace edge, a female's is placed exactly on the edge if not nearer to the plastron. The base of the tail of the male is also thicker as compared to that of the female because of the hidden reproductive organs. The inside of the turtle's mouth is camouflaged, and it possesses a vermiform (i.e., "worm-shaped") appendage on the tip of its tongue used to lure fish, a form of aggressive mimicry.
|
|
These nematodes have the general nematode life cycle with four juvenile stages keeping their vermiform shape throughout the entire life cycle except the egg stage. Any of the stages, except the egg and J1 which molts inside the egg, can infect the root. The nematodes get inside the roots and move throughout the root laying eggs individually in the root cortex and maybe a few in the soil. This particular species of Pratylenchus reproduces by parthenogenesis.

Teredo navalis from Popular Science Monthly, September 1878 Removed from its burrow, the fully grown teredo ranges from several centimetres to about a metre in length, depending on the species. The body is cylindrical, slender, naked and superficially vermiform, meaning "worm-shaped". In spite of their slender, worm-like forms, shipworms possess the characteristic morphology of bivalves. The ctinidia lie mainly within the branchial siphon, through which the animal pumps the water that passes over the gills.

|
The larvae feed on Nothopanax simplex and Nothopanax sinclairii. They mine the leaves of their host plant. The mine has the form of a simple gallery throughout, and is vermiform in character, the loops being very closely applied to one another, but never crossing. As a rule the gallery at first winds backwards and forwards in slightly increasing distances, closely applied to itself, and in a direction more or less parallel to the long axis of the leaf.
|
|
In the earlier part the mine is a simple vermiform gallery. Later, however, instead of ending in a somewhat tortuous and widened gallery, it expands into a relatively large blotch, which may occupy the entire leaf, or all or the greater part of one half of the leaf in larger leaves. The entire mine is on the upper surface of the leaf, and is pale green in colour. The midrib forms a barrier in its basal two-thirds.

Caecilians (; New Latin for "blind ones") are a group of limbless, vermiform or serpentine amphibians. They mostly live hidden in the ground and in stream substrates, making them the least familiar order of amphibians. All modern caecilians and their closest fossil relatives are grouped as a clade, Apoda, within the larger group Gymnophiona, which also includes more primitive extinct caecilian-like amphibians. Caecilians are mostly distributed in the tropics of South and Central America, Africa, and southern Asia.

As a Zoroastrian dies of side sickness, Rob learns from him that Zoroastrianism does not prohibit an adherent from undergoing autopsy after death. Rob secretly performs an autopsy on his body to deepen his knowledge of anatomy and to discover the inflamed vermiform appendix. When the mullahs discover what he has done, both Rob and Ibn Sina are being sentenced to death for necromancy. Rebecca is about to be stoned for adultery, when the Shah is apparently stricken with side sickness.

With its vermiform body, a putatively multi-functional radula, ‘simplified’ organ systems and a special fast and imprecise mode of sperm transfer, Pontohedyle reflects a meiofaunal slug lineage highly adapted to its interstitial habitat. Pontohedyle is morphologically well-defined genus of meiofaunal slugs. Specimens of Pontohedyle are externally uniform and easily distinguishable from other acochlids by the lack of rhinophores and the bow- shaped oral tentacles. Pontohedyle typically bear monaxone, rodlet-like spicules distributed randomly and frequently accumulated between the oral tentacles.

Genetic engineers Clive Nicoli and Elsa Kast hope to achieve fame by splicing animal DNA to create hybrids for medical use at the company N.E.R.D. (Nucleic Exchange Research and Development). Their work previously yielded Fred, a dog-sized vermiform creature intended as a mate for their female specimen, Ginger. After successfully mating them, Clive and Elsa plan to create a human-animal hybrid that could revolutionize science. Their employers Joan Chorot of N.E.R.D. and William Barlow forbid them from doing this.

Vestigial structures are anatomical structures of organisms in a species which are considered to have lost much or all of their original function through evolution. These body parts can be classed as additional to the required functioning of the body. In human anatomy the vermiform appendix is sometimes classed as a vestigial remnant. Prosthesis is an artificial extension that replaces a body part, and cybernetics is the study of computer technology in relation to organisms which can include replacement or additional body parts.

Jant, familiar with the city's underworld from his youth, agrees to search for her. In Hacilith, he locates Cyan but she refuses to return with him, having tired of her life as a secluded noblewoman. That night, Jant discovers Cyan unconscious in the throes of the drug scolopendium, and takes her to the immortal doctor, Rayne. There he is approached by the Vermiform, a creature from the alternate world of the Shift, which Jant has previously accessed through the use of scolopendium.

Where lizards typically have one or two varying patterns or shapes of osteoderms, komodo's have four: rosette, platy, dendritic, and vermiform. This rugged hide makes Komodo dragon skin a poor source of leather. Additionally, these osteoderms become more extensive and variable in shape as the Komodo dragon ages, ossifying more extensively as the lizard grows. These osteoderms are absent in hatchlings and juveniles, indicating that the natural armor develops as a product of age and competition between adults for protection in intraspecific combat over food and mates.

The following year Berry was appointed lecturer in anatomy at the school of medicine of the Royal Colleges. On receipt of his MD in 1894 he had written a prize-winning thesis on the Vermiform appendix. Berry was held in very high regard within the institution and was a greatly respected and well established academic. In 1895 Berry was elected a Fellow of the Royal College of Surgeons of Edinburgh and the following year began to lecture in anatomy at the University of Edinburgh.

Siboglinidae is a family of polychaete annelid worms whose members made up the former phyla Pogonophora and Vestimentifera (the giant tube worms). They are composed of about 100 species of vermiform creatures and live in thin tubes buried in sediments (Pogonophora) or in tubes attached to hard substratum (Vestimentifera) at ocean depths from . They can also be found in association with hydrothermal vents, methane seeps, sunken plant material, or whale carcasses. The first specimen was dredged from the waters of what is now Indonesia in 1900.

The Euarchontoglires clade is based on DNA sequence analyses and retrotransposon markers that combine the clades Glires (Rodentia + Lagomorpha) and Euarchonta (Scandentia + Primates + Dermoptera). So far, few if any distinctive anatomical features have been recognized that support Euarchontoglires, nor does any strong evidence from anatomy support alternative hypotheses. Although both Euarchontoglires and diprotodont marsupials are documented to possess a vermiform appendix this feature evolved as a result of convergent evolution. Euarchontoglires is now recognized as one of the four major subclades within the clade Eutheria (i.e.

The appendicular artery, also known as appendiceal artery, commonly arises from the terminal branch of the ileocolic artery, or less commonly from the posterior cecal artery or an ileal artery. It descends behind the termination of the ileum and enters the mesoappendix of the vermiform appendix. It runs near the free margin of the mesoappendix and ends in branches which supply the appendix. Micrograph of entry point of appendicular arteries (arrows at level of inner muscular layer), not to be confused with a perforation.

Knaust & Desrochers (2019) reported fossils of vermiform organisms with a wide range of morphologies occurring on bedding planes from the Late Ordovician (Katian) Vauréal Formation (Canada). In the specimens preserving the anterior end of the body, this end is pointed or rounded, bearing a rhynchocoel with the proboscis, which is characteristic for nemerteans. The authors attributed these fossils to nemerteans and interpreted them as the oldest record of the group reported so far. However, Knaust & Desrochers cautioned that partly preserved putative nemertean fossils might ultimately turn out to be fossils of turbellarians or annelids.

All nematodes pass through an embryonic stage, four juvenile stages (J1–J4) and an adult stage. Juvenile Meloidogynes parasites hatch from eggs as vermiform, second-stage juveniles (J2), the first moult having occurred within the egg. Newly hatched juveniles have a short free-living stage in the soil, in the rhizosphere of the host plants. They may reinvade the host plants of their parent or migrate through the soil to find a new host root. J2 larvae do not feed during the free-living stage, but use lipids stored in the gut.

This species' mycelium is densely produced from all of its orifices and sutures; it is initially a silky white, becoming a ginger colour. Its stromata is single, produced from a dorsal pronotum measuring between and in length, which is cylindrical, dark brown at its base, and pinkish in the fertile upper part. The ascomata are immersed and flask-shaped, measuring up to , including a short ostiole. Its asci are 8-spored, hyaline and cylindrical, while the ascospores are multiserriate and vermiform; its apex is acute, with a rounded base.

Adult males remain vermiform and get out of the root while females swell and obtain the pyriform/round shape. Females lay eggs in the gelatinous matrix which hatch again and the cycle is repeated if environmental conditions are favorable.Siddharth Tiwari and, Jon D. Eisenback, Roger R. Youngman, 2009. Root-knot Nematode in Field Corn Department of Entomology, Virginia Tech 2Department of Plant Pathology, Physiology, and Weed Science, Virginia Tech 3Extension Entomologist, Virginia Tech The length of the life cycle depends on environmental factors mostly temperature and host status.

The nematode then molts from the J2 to J3, J3 to J4, and finally J4 into an adult. J2, J3, J4, and adults all have a vermiform, worm- like shape, and can all invade the roots. Entry into the roots is accomplished by mechanical pressure and cutting action of the stylet of the nematode, usually just behind the root cap but may occur through other surfaces of the roots, rhizomes, or tubers. The nematode feeds on the cells within the root, usually until the cell lyses and cavities are formed.

He was first Principal Surgeon to the Westminster Hospital, and founder and first Principal Surgeon to St George's Hospital. On 5 April 1716 he was elected a Fellow of the Royal Society under the name Claude Amyand. In 1722, he inoculated three of the children of the Prince and Princess of Wales against smallpox, following the introduction of the process into the country from Turkey by Lady Mary Wortley Montagu. At St George's Hospital, on 6 December 1735, he performed the first recorded successful appendicectomy (which is the surgical removal of the vermiform appendix).

Pacific hagfish trying to hide under a rock Hagfish are long and vermiform, and can exude copious quantities of a milky and fibrous slime or mucus from some 100 glands or invaginations running along their flanks. The species Myxine glutinosa was named for this slime. When captured and held, e.g., by the tail, they secrete the microfibrous mucus, which expands into up to 20 litres (5¼ US gallons) of sticky, gelatinous material when combined with water; one litre of slime has about 40 milligrams of mucus and proteins.

Buddenbrokia plumatellae is a worm-like parasite of bryozoans whose taxonomic placement long puzzled biologists. It is now classified as one of only three myxozoans in the Malacosporea subclass and its only family, Saccosporidae, on the basis of both genetic and ultrastructural studies. It was the first multicellular myxozoan identified and its vermiform shape initially gave strong support to the theory that the enigmatic group belongs among the Bilateria. Five years later, this was refuted by a study of fifty genes from this same "worm", which had rarely even been seen since its discovery in 1851.

The first molt happens within the egg, so at the time of hatching, P. alleni juveniles are in their second juvenile stage (J2). They are able to enter the root and infect throughout all of their life stages, minus the egg and J1 stages, as they are not yet mobile. As a migratory endoparasite, these pests move freely throughout the root to feed and reproduce, destroying host cells and tissue as they move intracellularly. They remain vermiform throughout their life cycle, and can be found within the roots, or within soil after their host dies and can no longer support them.

Since its formation, however, Bastard Noise has made releases with underground labels such as Three One G, Relapse Records, Gravity Records, Deep Six, Vermiform Records, Robotic Empire, among others. For live performances, Wood often recruits other musicians to perform with him, the likes of which have included Merzbow, Justin Pearson and Keiji Haino. Instruments such as the bass guitar and the drum kit were later incorporated down the band's history. Wood has expressed distaste for digital piracy and prefers to release his music elusively on physical formats, although he has made few digital-only releases in the past.

Once the prey is in striking range, the snake captures the prey. Due to the tail resembling a writhing caterpillar and another worm-like insect larvae, the tail of the snake is often referred to as a vermiform. One elaborate example of caudal luring occurs in the spider- tailed horned viper, which employs a highly modified tail to mimic a spider's form and locomotion. Footage of the spider-tailed horned viper using its tail to lure a migrating bird featured in the Asia episode of the BBC series Seven Worlds, One Planet narrated by David Attenborough.

Usually very old males comprise the specimens that weigh in excess of per most population studies. Among extant freshwater turtles, only the little-known giant softshell turtles of the genera Chitra, Rafetus, and Pelochelys, native to Asia, reach comparable sizes.

In humans the vermiform appendix is a vestigial structure; it has lost much of its ancestral function. Vestigiality is the retention during the process of evolution of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. Assessment of the vestigiality must generally rely on comparison with homologous features in related species. The emergence of vestigiality occurs by normal evolutionary processes, typically by loss of function of a feature that is no longer subject to positive selection pressures when it loses its value in a changing environment.

The lagerstätte, discovered and first published in 1996, provides a wider representation of organisms than conventional fossilizations of shelly and bony elements. The Wenlock Series offers a diverse macrofauna that includes polychaete worms (Kenostrychus), sponges, graptolites, starfish, a chelicerate (Offacolus), a stem-group mandibulate (Aquilonifer) and a vermiform mollusc (Acaenoplax). On the microscopic scale the diverse microfauna includes abundant well-preserved radiolarians. The delicate Wenlock fossils are difficult to separate from split sections, so Mark Sutton and his team have devised a method of serially grinding sections; from digital photographs three-dimensional "digital fossils" are reconstructed from datasets.

Critics of the precocious eclosion theory also argue that the larval forms of holometabolans are very often more specialized than those of hemimetabolans. X. Belles illustrates that the maggot of a fruitfly "cannot be envisaged as a vermiform and apodous (legless) creature that hatched in an early embryonic stage." It is in fact extremely specialized: for example, the cardiostipes and dististipes of the mouth are fused, as in some mosquitoes, and these parts are also fused to the mandibles and thus form the typical mouth hooks of fly larvae. Maggots are also secondarily, and not primitively, apodous.

As shown in the accompanying pictures however, the human appendix typically is about comparable to that of the rabbit's in size, though the caecum is reduced to a single bulge where the ileum empties into the colon. Some carnivorous animals may have appendices too, but seldom have more than vestigial caeca.Peter Robert Cheeke, Ellen S. Dierenfeld, Comparative Animal Nutrition and Metabolism. Publisher: CABI; 2010 In line with the possibility of vestigial organs developing new functions, some research suggests that the appendix may guard against the loss of symbiotic bacteria that aid in digestion, though that is unlikely to be a novel function, given the presence of vermiform appendices in many herbivores.

Some plants are impacted more than others, for instance, the damage threshold of P. alleni on soybeans is 14 nematodes/100cc or 1cm³ soil. Their vermiform shape and mobility allow them to enter the root and move freely throughout, feeding on the parenchyma tissue of the root cortex. This feeding causes a reduction of plant growth, less lateral roots, loss of cytoplasm in infected cells, redish brown necrotized lesions, as well as predisposing the damaged roots to fungi and bacteria that can initiate a secondary infection. Using their stylet, Pratylenchus nematodes secrete wall degrading enzymes that help to break down cell walls and allow for more ease of movement.

Almost all karyorelictean species, except Loxodes, have been described from the marine interstitial habitat, where they live in the pore- water spaces between sediment grains. Animals from such habitats are known as meiofauna, and karyorelicteans have many morphological similarities to meiofaunal animals despite being protists: most karyorelicteans are relatively large (1 mm or more in length), have a worm-like (vermiform) body shape with an elongated tail, and exhibit thigmotactic behavior. Most karyorelicteans feed on bacteria or algae, and prefer microaerobic conditions. However, one genus, Kentrophoros, lacks an oral apparatus and feeds instead on symbiotic sulfur-oxidizing bacteria that are attached to one side of the cell.

Characteristic features of the Digenea include a syncytial tegument; that is, a tegument where the junctions between cells are broken down and a single continuous cytoplasm surrounds the entire animal. A similar tegument is found in other members of the Neodermata; a group of platyhelminths comprising the Digenea, Aspidogastrea, Monogenea and Cestoda. Digeneans possess a vermiform, unsegmented body-plan and have a solid parenchyma with no body cavity (coelom) as in all platyhelminths. Anterior sucker of Overstreetia cribbi a zoogonid digenean There are typically two suckers, an anterior oral sucker surrounding the mouth, and a ventral sucker sometimes termed the acetabulum, on the ventral surface.

Hydrothermal vent tubeworms get organic compounds from bacteria that live in their trophosome. Isolating the vermiform body from white chitonous tube, a small difference exists from the classic three subdivisions typical of phylum Pogonophora: the prosoma, the mesosoma, and the metasoma. R. pachyptila community with extroflexion of red branchial plume The first body region is the vascularized branchial plume, which is bright red due to the presence of hemoglobin that contain up to 144 globin chains (each presumably including associated heme structures). These tube worm hemoglobins are remarkable for carrying oxygen in the presence of sulfide, without being inhibited by this molecule, as hemoglobins in most other species are.

These fungi spores begin as cylindrical or vermiform type hyaline and are non-septate, for this reason they can not be considered as Podospora spores. Lundqvist also believed that these 3 fungal species have evolved independently from a species closely related to the family Lasiosphaeria. Much later on in 1998 M.J. Richardson studied these three fungal species in-depth gathering samples from various regions of Sweden and France. Upon examination of the spores characteristics such as spore length and width and ampullate hair presence, Richardson concluded that these three species can all be considered the same species with the correct name being Anopodium ampullaceum.

By day, it may try to attract fish and other prey by sitting quietly at the bottom of murky water and letting its jaws hang open to reveal its tongue appendage, which looks like a small, pink, worm in the back of its gray mouth, and lure the prey into striking distance. The vermiform tongue imitates the movements of a worm, luring prey to the turtle's mouth. The mouth is then closed with tremendous speed and force, completing the ambush. Although the turtle does not actively hunt its prey, it can detect chemosensory cues from prey, like the mud turtle in order to choose the location in which it is most likely to catch food.

Unwound's influences included Sonic Youth, Melvins, Fugazi, The Jesus Lizard, Wipers, Black Flag, Can, Mission of Burma, Hüsker Dü, Nation of Ulysses, Flipper, and Gang of Four. Evidence of the Black Flag influence can be seen in Trosper and Sandeno's side band with Tim Green (of Nation of Ulysses), The Young Ginns (named after Black Flag guitarist/songwriter Greg Ginn), and in their interpolation of Black Flag's lyric "I'm not a machine" in their song "Machine" (on Replikants' debut album). Trosper and Sandeno were also in a band called Worst Case Scenario that released an album on Vermiform Records. Unwound's early work was characterized by intense vocals, jagged guitar lines, and more complex drumming than the band's peers.

First, the musculature of the intestinal tract is described in detail, followed by an extensive discussion of the form, function, and position of the stomach. According to the text, the stomach is spherical; the stomach wall has an internal lining, which is "the seat of sensation", and an external fleshy coat that is involved in digestion. In order to access the spleen, which was thought to secrete black bile into the stomach through imaginary canals, the dissector was required to remove the "false ribs". The liver is said to have five lobes, the gallbladder is described as the seat of yellow bile, and the cecum is described with no mention of the vermiform appendix.

The band was formed by three former members of the hardcore punk group Born Against: singer and guitarist Adam Nathanson (also ex-Life's Blood), drummer Brooks Headley (also ex-Universal Order of Armageddon) and harmonica player Neil Burke (also ex-Life's Blood). Burke's tenure was brief, and his departure after the group's debut EP on Vermiform Records was followed by Avail singer Tim Barry joining on bass guitar in 1994. Barry was replaced in 1995 by bassist Marty Key, known as Marty Violence, shortly before the group signed to California-based punk rock label Lookout! Records. Headley left the group in 1997 and was briefly replaced by Jonathan Fuller (of Sleepytime Trio) and more permanently by Fred LaPier, who played with the group through their final years.

Its course invariably takes it close around the greater portion or entire margin of the leaf, closely following the digitations and any incursions made by other insects, and also along one or both of the sides of the midrib, this forming a barrier only in its basal three-quarters. The gallery then follows a more or less tortuous course within these boundaries. If the leaf is large it will rarely cross earlier parts of its own track, and will wander in a vermiform manner along one half of the leaf, generally that half opposite the one on which the egg was laid. In smaller leaves, almost the entire upper surface will be mined in a very complicated manner, but there is never any tendency to blotch formation.

Las Hoyas was an inland lacustrine environment which presents an important aquatic and terrestrial flora (with many specimens of Charophytes, Montsechia, Weischelia or Frenelopsis) and diverse fauna, with specimens of at least five or six Phyla: arthropods, molluscs, Chordata and many vermiform soft bodied animals which might be Nemertines or annelids. Among vertebrates the most abundant and diverse group are fish. The presence of mostly articulated skeletons, exceptional preservation of tissue and lack of any other signs of transportation may indicate that these are demic and autochthonous entities (meaning that they lived and died in the same place where they fossilized). Tapejarid pterosaur Europejara and basal ornithomimosaur Pelecanimimus in a speculative ecologic competition Crocodylomorphs are the most abundant amniotes from Las Hoyas.

Haslin participated in the first-ever MLB night game that season, driving in the Phillies only run against the Cincinnati Reds in a 2–to–1 loss. During the season, it was reported that Haslin carried around a lump of coal as a good-luck charm, and a reminder of how far he has come from his days of mining in his home-town of Wilkes-Barre, Pennsylvania. In late-August, it was discovered that Haslin had appendicitis, causing him to miss time after recovering from emergency surgery to remove his vermiform appendix at Sacred Heart Hospital in Allentown, Pennsylvania. On the season, he batted .265 with 53 runs scored, 108 hits, 17 doubles, three triples, three home runs, 52 RBIs, and five stolen bases in 110 games played.

Then it changes its direction for one almost at right angles to the earlier one, now crossing the leaf in curved sweeps from edge to midrib, this latter forming a certain obstacle to trespass on the other half of the leaf. On reaching the upper region of the leaf the mine becomes less vermiform in character and becomes rather tortuous in its direction, crossing the midrib in its upper and thinner part, and continuing down the other half of the leaf in more or less close proximity to the midrib or outer margin. This latter portion of the mine is often deeper in the leaf than the earlier part. The entire mine is in the upper surface of the leaf, and no trace of it can be seen beneath.

J.W. Truman and L.M. Riddiford, in 1999, revitalized the precocious eclosion theory with a focus on endocrine control of metamorphosis. They postulated that hemimetabolan species hatch after three embryonic "moults" into a nymphal form similar to the adult, whereas holometabolan species hatch after only two embryonic 'moults' into vermiform larvae that are very different from the adult. In 2005, however, B. Konopová and J. Zrzavý reported ultrastructural studies across a wide range of hemimetabolan and holometabolan species and showed that the embryo of all species in both groups produce three cuticular depositions. The only exception was the Diptera Cyclorrhapha (unranked taxon of "high" Dipterans, within the infraorder Muscomorpha, which includes the highly studied Drosophila melanogaster) which has two embryonic cuticles, most likely due to secondary loss of the third.

The issue is controversial and not without dispute; nonetheless, vestigial organs are common evolutionary knowledge. In addition, the term vestigiality is useful in referring to many genetically determined features, either morphological, behavioral, or physiological; in any such context, however, it need not follow that a vestigial feature must be completely useless. A classic example at the level of gross anatomy is the human vermiform appendix—though vestigial in the sense of retaining no significant digestive function, the appendix still has immunological roles and is useful in maintaining gut flora. Similar concepts apply at the molecular level—some nucleic acid sequences in eukaryotic genomes have no known biological function; some of them may be "junk DNA", but it is a difficult matter to demonstrate that a particular sequence in a particular region of a given genome is truly nonfunctional.

However, Jan Swammerdam conducted a dissection study and showed that pupal forms are not egg-like, but instead more of a transitional stage between larvae and adult. In 1883, John Lubbock revitalized Harvey's hypothesis and argued that the origin and evolution of holometabolan development can be explained by the precocious eclosion of the embryo. Hemimetabolan species, whose larvae look like the adult, have an embryo that completes all developmental stages (namely: "protopod", "polipod", and "oligopod" stages) inside the eggshell. Holometabolan species instead have vermiform larvae and a pupal stage after incomplete development and hatching. The debate continued through the twentieth century, with some authors (like Charles Pérez in 1902) claiming the precocious eclosion theory outlandish, Antonio Berlese reestablishing it as the leading theory in 1913, and Augustus Daniel Imms disseminating it widely among Anglo-Saxon readers from 1925 (see Wigglesworth 1954 for review).

The family Centrolenidae is a clade of anurans. Previously, the family was considered closely related to the family Hylidae; however, recent phylogenetic studies have placed them (and their sister taxon, the family Allophrynidae) closer to the family Leptodactylidae. The monophyly of Centrolenidae is supported by morphological and behavioral characters, including:1) presence of a dilated process on the medial side of the third metacarpal (an apparently unique synapomorphy); 2) ventral origin of the musculus flexor teres digiti III relative to the musculus transversi metacarpi I; 3) terminal phalanges T-shaped; 4) exotroph, lotic, burrower/fossorial tadpoles with a vermiform body and dorsal C-shaped eyes, that live buried within leaf packs in still or flowing water systems; and 5) eggs clutches deposited outside of water on vegetation or rocks above still or flowing water systems. Several molecular synapomorphies also support the monophyly of the clade.
