Most of the dorsal metacarpal arteries arise from the dorsal carpal arch and run downward on the second, third, and fourth dorsal interossei of the hand and bifurcate into the dorsal digital arteries. Near their origin, they anastomose with the deep palmar arch by perforating arteries. They also anastomose with common palmar digital arteries (from the superficial palmar arch), also via perforating arteries. The first dorsal metacarpal artery arises directly from the radial artery before it crosses through the two heads of the first dorsal interosseous muscle.

They anastomose freely in the subcutaneous tissue of the finger tips and by smaller branches near the interphalangeal joints. Each also gives off a couple of dorsal branches which anastomose with the dorsal digital arteries, and supply the soft parts on the back of the second and third phalanges, including the matrix of the fingernail. The proper palmar digital artery for the medial side of the little finger arises directly from the ulnar artery deep to the palmaris brevis muscle, but the rest arise from the common palmar digital arteries.

The esophageal branches of the inferior thyroid artery supply the esophagus, and anastomose with the esophageal branches of the aorta. The ascending cervical artery is a small branch which arises from the inferior thyroid artery as it passes behind the carotid sheath; it runs up on the anterior tubercles of the transverse processes of the cervical vertebrae in the interval between the anterior scalene muscle and the longus capitis. The ascending cervical artery gives twigs to the neck muscles and these anastomose with branches of the vertebral arteries. One or two spinal branches are sent into the spinal canal, through the intervertebral foramina to be distributed to the spinal cord and its membranes, and to the bodies of the vertebrae.

|
The thallus is made up of filaments of the fungus called hyphae. The filaments grow by branching then rejoining to create a mesh, which is called being "anastomose". The mesh of fungal filaments may be dense or loose. Generally, the fungal mesh surrounds the algal or cyanobacterial cells, often enclosing them within complex fungal tissues that are unique to lichen associations.

It descends through the greater palatine canal with the greater and lesser palatine branches of the pterygopalatine ganglion, and, emerging from the greater palatine foramen, runs forward in a groove on the medial side of the alveolar border of the hard palate to the incisive canal; the terminal branch of the artery passes upward through this canal to anastomose with the sphenopalatine artery.
|
|
The sphenopalatine artery passes through the sphenopalatine foramen into the cavity of the nose, at the back part of the superior meatus. Here it gives off its posterior lateral nasal branches which spread forward over the conchæ and meatuses, anastomose with the ethmoidal arteries and the nasal branches of the descending palatine, and assist in supplying the frontal, maxillary, ethmoidal, and sphenoidal sinuses.

The small intestine receives a blood supply from the celiac trunk and the superior mesenteric artery. These are both branches of the aorta. The duodenum receives blood from the coeliac trunk via the superior pancreaticoduodenal artery and from the superior mesenteric artery via the inferior pancreaticoduodenal artery. These two arteries both have anterior and posterior branches that meet in the midline and anastomose.

|
In circulatory anastomoses, many arteries naturally anastomose with each other; for example, the inferior epigastric artery and superior epigastric artery, or the anterior and/or posterior communicating arteries in the Circle of Willis in the brain. The circulatory anastomosis is further divided into arterial and venous anastomosis. Arterial anastomosis includes actual arterial anastomosis (e.g., palmar arch, plantar arch) and potential arterial anastomosis (e.g.

The ascospores have ellipsoidal to roughly cylindrical shapes, usually with blunt ends, and measure 19–22 by 10–12 µm. They have smooth surfaces and usually contain two large oil drops. The paraphyses (sterile, filamentous hyphae present in the hymenium) are cylindrical, 2–3 µm thick, barely enlarged at their apices, straight, and mostly unbranched above. They may sometimes anastomose, but do not form a conspicuous network.

The posterior cerebral artery (PCA) is one of a pair of arteries that supply oxygenated blood to the occipital lobe, part of the back of the human brain. The two arteries originate from the distal end of the basilar artery, where it bifurcates into the left and right posterior cerebral arteries. These anastomose with the middle cerebral arteries and internal carotid arteries via the posterior communicating arteries.
|
|
The inferior cerebral veins are veins that drain the undersurface of the cerebral hemispheres and empty into the cavernous and transverse sinuses. Those on the orbital surface of the frontal lobe join the superior cerebral veins, and through these open into the superior sagittal sinus. Those of the temporal lobe anastomose with the middle cerebral and basal veins, and join the cavernous, sphenoparietal, and superior petrosal sinuses.
|
|
The inferior tympanic artery is a small branch of the ascending pharyngeal artery. It is a small branch which passes through a minute foramen in the petrous portion of the temporal bone which is called tympanic canaliculus or inferior tympanic canaliculus, in company with the tympanic branch of the glossopharyngeal nerve, to supply the medial wall of the tympanic cavity and anastomose with the other tympanic arteries.

|
The sphenopalatine artery is a branch of the maxillary artery which passes through the sphenopalatine foramen into the cavity of the nose, at the back part of the superior meatus. Here it gives off its posterior lateral nasal branches. Crossing the under surface of the sphenoid, the sphenopalatine artery ends on the nasal septum as the posterior septal branches. Here it will anastomose with the branches of the greater palatine artery.

Over the centuries, the weight of these deposits crushed the shell fragments and compressed them into stone. It overlies the thin Glenwood Shale, which overlies the thick St. Peter Sandstone. It is shot through with dolomitic mottles in an anastomose pattern; this dolotimization occurred after deposition but prior to the development of joints in the rock. About 100 million years later, geologic forces raised southeastern Minnesota above the ocean surface.

|
The PCAs arise directly from the OA and are end arteries which is to say no PCA or any of its branches anastomose with any other artery. Consequently, sudden occlusion of any PCA will produce an infarct in the region of the choroid supplied by that particular PCA. Occlusion of a short or long PCA will produce a smaller choroidal infarct, within the larger area supplied by the specific parent PCA.

The edges of the pinnae may be smooth, or have small sharp or rounded teeth. The tips of the pinnae vary from blunt to sharp. On the underside of the blades, the veins are mostly free and rarely anastomose (reconnect with each other). The fertile blades bear from one to ten (rarely fifteen or more) sori per pinna or lobe; the sori are found along the whole length of the leaf.
|
|
The inferior gluteal veins (sciatic veins), or venæ comitantes of the inferior gluteal artery, begin on the upper part of the back of the thigh, where they anastomose with the medial femoral circumflex and first perforating veins. They enter the pelvis through the lower part of the greater sciatic foramen and join to form a single stem which opens into the lower part of the internal iliac vein.
|
|
The descending palatine artery branches off of the maxillary artery in the pterygopalatine fossa and descends through the greater palatine canal along with the greater palatine nerve (from the pterygopalatine ganglion). Once emerging from the greater palatine foramen, it changes names to the greater palatine artery and begins to supply the hard palate. As it terminates it travels through the incisive canal to anastomose with the sphenopalatine artery to supply the nasal septum.

The major clinical relevance is in the case of traumatic amputation of the penis, failure to perform re-anastomosis of the dorsal arteries leads to skin loss. On the penis, it lies between the dorsal nerve and deep dorsal vein, the former being on its lateral side. It supplies the integument and fibrous sheath of the corpus cavernosum penis, sending branches through the sheath to anastomose with the deep artery of the penis.

|
Blood flow to the brain in humans and some other animals is maintained via a network of collateral arteries that anastomose (join) in the circle of Willis, which lies at the base of the brain. In the circle of Willis so-called communicating arteries exist between the front (anterior) and back (posterior) parts of the circle of Willis, as well as between the left and right side of the circle of Willis.

The secondary veins arch towards the leaf margin in broadly convex to concave arches. The margins show large tooth-like serrations that are generally associated with smaller serrations on the basal side of the larger serrations. The samaras of A. chaneyi have moderately inflated nutlets and smoothly diverging veins which rarely anastomose. The overall shape of the nutlet is narrowly elliptic, with a rounded tip and approximate length of and a width of .

The tracheae are invaginations of the cuticular exoskeleton that branch (anastomose) throughout the body with diameters from only a few micrometres up to 0.8 mm. Diffusion of oxygen and carbon dioxide takes place across the walls of the smallest tubes, called tracheoles, which penetrate tissues and even indent individual cells. Gas may be conducted through the respiratory system by means of active ventilation or passive diffusion. Unlike vertebrates, insects do not generally carry oxygen in their haemolymph.

It passes lateralward, immediately below the oculomotor nerve, which separates it from the posterior cerebral artery, winds around the cerebral peduncle, close to the trochlear nerve, and, arriving at the upper surface of the cerebellum, divides into branches which ramify in the pia mater and anastomose with those of the anterior and posterior inferior cerebellar arteries. Several branches are given to the pineal body, the anterior medullary velum, and the tela chorioidea of the third ventricle.
|
|
The cerebellum is provided with blood from three paired major arteries: the superior cerebellar artery (SCA), the anterior inferior cerebellar artery (AICA), and the posterior inferior cerebellar artery (PICA). The SCA supplies the upper region of the cerebellum. It divides at the upper surface and branches into the pia mater where the branches anastomose with those of the anterior and posterior inferior cerebellar arteries. The AICA supplies the front part of the undersurface of the cerebellum.
|
|
The bronchial arteries supply blood to the bronchi and connective tissue of the lungs. They travel with and branch with the bronchi, ending about at the level of the respiratory bronchioles. They anastomose with the branches of the pulmonary arteries, and together, they supply the visceral pleura of the lung in the process. Note that much of the oxygenated blood supplied by the bronchial arteries is returned via the pulmonary veins rather than the bronchial veins.

The glands continue to develop but the duct systems anastomose. The main pancreatic duct is formed by the fusion of the dorsal and ventral pancreas. The embryology also explains the strange zig-zag course of the main pancreatic duct and the occasional appearance of an accessory pancreatic duct. The uncinate process, unlike the remainder of the organ, passes posteriorly to the superior mesenteric vein (it can pass posteriorly to the superior mesenteric artery, but this is less common).

|
Closer to the locule, the cells become more hyaline (translucent) and thin-walled; it is from this region that the pseudoparaphyses originate. The hamathecium (a term referring to all hyphae that develop between asci of the hymenium) is made of branched pseudoparaphyses measuring 3–6 μm in diameter. These pseudoparaphyses are embedded in a gelatinous matrix and anastomose above the asci, tapering at the tip to a length of about 1.5 μm while reaching into the ostiole.

In "Microscopic Anatomy of Invertebrates". Wiley-Liss, Inc. . The distribution of spiracles can vary greatly among the many orders of insects, but in general each segment of the body can have only one pair of spiracles, each of which connects to an atrium and has a relatively large tracheal tube behind it. The tracheae are invaginations of the cuticular exoskeleton that branch (anastomose) throughout the body with diameters from only a few micrometres up to 0.8 mm.

The hindwings are somewhat angular too, and have 8 veins. Of these, the first two run singly, while 3-5 approach, 6 and 7 join, and 7 and 8 anastomose at their bases. The only mark on the yellowish- brown wings is a short reddish transverse dash at the outer end of the forewing cell. Altogether, the most conspicuous differences from H. fimbrialis are the markedly shorter legs and antennae of the latter, as well as its white abdominal tuft.

The sublingual Artery arises at the anterior margin of the hyoglossus, and runs forward between the genioglossus and mylohyoid muscle to the sublingual gland. It supplies the gland and gives branches to the mylohyoideus and neighboring muscles, and to the mucous membrane of the mouth and gums. One branch runs behind the alveolar process of the mandible in the substance of the gum to anastomose with a similar artery from the other side; another pierces the mylohyoideus and anastomoses with the submental branch of the facial artery.

|
The dorsal carpal branch of the ulnar artery arises from the ulnar artery immediately above the pisiform bone, and winds backward beneath the tendon of the flexor carpi ulnaris; it passes across the dorsal surface of the carpus beneath the extensor tendons, to anastomose with a corresponding branch of the radial artery. Immediately after its origin, it gives off a small branch, which runs along the ulnar side of the fifth metacarpal bone, and supplies the ulnar side of the dorsal surface of the little finger.

Cortical radial arteries, formerly known as interlobular arteries, are renal blood vessels given off at right angles from the side of the arcuate arteries looking toward the cortical substance. The interlobular arteries pass directly outward between the medullary rays to reach the fibrous tunic, where they end in the capillary network of this part. These vessels do not anastomose with each other, but form end-arteries. In their outward course, they give off lateral branches, which are the afferent arterioles that supply the renal corpuscles.

|
Esophageal varices are swollen twisted branches of the azygous vein in the lower third of the esophagus. These blood vessels anastomose (join up) with those of the portal vein when portal hypertension develops. These blood vessels are engorged more than normal, and in the worst cases may partially obstruct the esophagus. These blood vessels develop as part of a collateral circulation that occurs to drain blood from the abdomen as a result of portal hypertension, usually as a result of liver diseases such as cirrhosis.

|
The assemblage referred to as "testate amoebae" is actually composed of several, unrelated groups of organisms. However, some features they all share that have been used to group them together include the presence of a test (regardless of its composition) and pseudopodia that do not anastomose. Testate amoebae can be found in most freshwater environments, including lakes, rivers, cenotes, as well as mires and soils. The strong and resistant nature of the tests allows them to be preserved long after the amoeba has died.

|
The inferior rectal artery arises from the internal pudendal artery as it passes above the ischial tuberosity. Piercing the wall of the pudendal canal, it divides into two or three branches which cross the ischioanal fossa, and are distributed to the muscles and integument of the anal region, and send offshoots around the lower edge of the gluteus maximus to the skin of the buttock. They anastomose with the corresponding vessels of the opposite side, with the superior and middle rectal arteries, and with the perineal artery.
|
|
Three other tropical genera of the family Sarcoscyphaceae, Phillipsia, Sarcoscypha, and Geodina, have brightly colored apothecia which might be confused with those of Cookeina. Although these genera may be distinguished microscopically because they all have asci which mature seriatim rather than simultaneously and paraphyses which do not anastomose to form a reticulum, distinguishing on the basis of macroscopic characters is less reliable. Species of Phyllipsia have apothecia that are saucer-shaped to discoid, thick-fleshed, and usually sessile. In Sarcoscypha the apothecia vary from saucer-shaped to cup-shaped and are usually stipitate.
|
|
These primary and secondary veins are considered major veins or lower order veins, though some authors include third order. Each subsequent branching is sequentially numbered, and these are the higher order veins, each branching being associated with a narrower vein diameter. In parallel veined leaves, the primary veins run parallel and equidistant to each other for most of the length of the leaf and then converge or fuse (anastomose) towards the apex. Usually, many smaller minor veins interconnect these primary veins, but may terminate with very fine vein endings in the mesophyll.

The inferior thyroid artery is an artery in the neck. It arises from the thyrocervical trunk and passes upward, in front of the vertebral artery and longus colli muscle. It then turns medially behind the carotid sheath and its contents, and also behind the sympathetic trunk, the middle cervical ganglion resting upon the vessel. Reaching the lower border of the thyroid gland it divides into two branches, which supply the postero-inferior parts of the gland, and anastomose with the superior thyroid artery, and with the corresponding artery of the opposite side.

Carotid arteries Multiple arteries supply blood to the nose; the nasal septum, shown here is supplied by the anterior and posterior ethmoidal arteries at top; the sphenopalantine artery at the back, and the anterior ethoidal artery and the superior labial artery over the cartilage. These arteries join together at alt= The blood supply to the nose is provided by branches of the ophthalmic, maxillary, and facial arteries – branches of the carotid arteries. Branches of these arteries anastomose to form plexuses in and under the nasal mucosa. In the septal region Kiesselbach's plexus is a common site of nosebleeds.
|
|
The pancreatic branches or pancreatic arteries are numerous small vessels derived from the splenic artery as it runs behind the upper border of the pancreas, supplying its body and tail. One of these, larger than the rest, is sometimes given off near the tail of the pancreas; it runs from left to right near the posterior surface of the gland, following the course of the pancreatic duct, and is called the greater pancreatic artery. These vessels anastomose with the pancreatic branches of the superior and inferior pancreaticoduodenal artery that are given off by the gastroduodenal artery and superior mesenteric artery respectively.
|
|
The branches of the inferior thyroid artery are the inferior laryngeal, the oesophageal, the tracheal, the ascending cervical and the pharyngeal arteries. The inferior laryngeal artery climbs the trachea to the back part of the larynx under cover of the inferior pharyngeal constrictor muscle. It is accompanied by the recurrent nerve, and supplies the muscles and mucous membrane of this part, anastomosing with the branch from the opposite side, and with the superior laryngeal branch of the superior thyroid artery. The tracheal branches of the inferior thyroid artery are distributed on the trachea, and anastomose below with the bronchial arteries.
|
|
The transverse facial artery is given off from the superficial temporal artery before that vessel leaves the parotid gland; running forward through the substance of the gland, it passes transversely across the side of the face, between the parotid duct and the lower border of the zygomatic arch, and divides into numerous branches, which supply the parotid gland and parotid duct, the masseter muscle, and the integument, and anastomose with the facial artery, the masseteric artery, the buccinator artery, and the infraorbital artery. This vessel rests on the masseter, and is accompanied by one or two branches of the facial nerve.

The superior ulnar collateral artery (inferior profunda artery), of small size, arises from the brachial artery a little below the middle of the arm; it frequently springs from the upper part of the a. profunda brachii. It pierces the medial intermuscular septum, and descends on the surface of the medial head of the Triceps brachii to the space between the medial epicondyle and olecranon, accompanied by the ulnar nerve, and ends under the Flexor carpi ulnaris by anastomosing with the posterior ulnar recurrent, and inferior ulnar collateral. It sometimes sends a branch in front of the medial epicondyle, to anastomose with the anterior ulnar recurrent.

|
In human anatomy, the inferior mesenteric artery, often abbreviated as IMA, is the third main branch of the abdominal aorta and arises at the level of L3, supplying the large intestine from the distal transverse colon to the upper part of the anal canal. The regions supplied by the IMA are the descending colon, the sigmoid colon, and part of the rectum. Proximally, its territory of distribution overlaps (forms a watershed) with the middle colic artery, and therefore the superior mesenteric artery. The SMA and IMA anastomose via the marginal artery of the colon (artery of Drummond) and via Riolan's arcade (also called the "meandering artery", an arterial connection between the left colic artery and the medial colic artery).

|
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.
|
|
On the underside of the blade, the veins are difficult to see and anastomose (split and rejoin each other), forming a series of areoles (the small areas enclosed by the veins) near the rachis. Fertile fronds are usually larger than sterile fronds, but their shape is otherwise the same. The base of the blade is typically heart-shaped (with the stipe protruding from the cleft); the bulges on either side of the cleft are frequently enlarged into auricles (rounded lobes), or occasionally into sharply-pointed, tapering lobes. The leaf tips may be rounded but are typically very long and attenuate (drawn out); the attenuate tips are capable of sprouting roots and growing into a new plant when the tip touches a surface suitable for growth.

|
It arises from the external iliac artery, immediately above the inguinal ligament. It curves forward in the subperitoneal tissue, and then ascends obliquely along the medial margin of the abdominal inguinal ring; continuing its course upward, it pierces the transversalis fascia, and, passing in front of the linea semicircularis, ascends between the Rectus abdominis and the posterior lamella of its sheath. It finally divides into numerous branches, which anastomose, above the umbilicus, with the superior epigastric branch of the internal thoracic artery and with the lower intercostal arteries. As the inferior epigastric artery passes obliquely upward from its origin it lies along the lower and medial margins of the abdominal inguinal ring, and behind the commencement of the spermatic cord.
|
|
It gives branches to the deltoid muscle (which, however, primarily is supplied by the posterior circumflex humeral artery) and to the muscles between which it lies; it supplies an occasional nutrient artery which enters the humerus behind the deltoid tuberosity. A branch ascends between the long and lateral heads of the triceps brachii to anastomose with the posterior humeral circumflex artery; the medial collateral artery, a branch, descends in the middle head of the triceps brachii and assists in forming the anastomosis above the olecranon of the ulna; and, lastly, a radial collateral artery runs down behind the lateral intermuscular septum to the back of the lateral epicondyle of the humerus, where it anastomoses with the interosseous recurrent and the inferior ulnar collateral arteries.

|
The membrane of the forewing has one or two cells from which about 7-8 branching veins emerge that may have branches that fuse together (anastomose) while the main veins reach the margins of the wing. They have three tarsal segments. They can be very difficult to separate from some members of the family Largidae, which also share some of these characters and belong to the same super family. Largids tend to have the edge of the pronotum (the top of the first thoracic segment) rounded but the taxonomic feature for separating them is the found only in females; female largids have the sixth visible (actually the seventh) abdominal segment appearing to be split in the middle whereas female pyrrhocorids have this undivided.

Its terminal branches, escaping from the gland, are distributed to the eyelids and conjunctiva: of those supplying the eyelids, two are of considerable size and are named the lateral palpebral arteries; they run medially in the upper and lower lids respectively and anastomose with the medial palpebral arteries, forming an arterial circle in this situation. The lacrimal artery also give off one or two zygomatic branches, one of which passes through the zygomatico-temporal foramen, to reach the temporal fossa, and anastomoses with the deep temporal arteries; another appears on the cheek through the zygomatico-facial foramen, and anastomoses with the transverse facial. A recurrent branch passes backward through the lateral part of the superior orbital fissure to the dura mater, and anastomoses with a branch of the middle meningeal artery.

A brown pseudoparenchyma covers the top of immature ascomata and rips apart at maturity; the tips of the pseudoparaphyses extend into the ostiole. The peridium is 9–13 μm thick, made of 4–5 layers of ellipsoidal cells, occluded by melanin, especially around the ostiole, to form a textura angularis—a parenchyma-like tissue of densely packed cells that appear angular in cross section. The hamathecium (a term referring to all hyphae developing between asci of the hymenium) is dense, containing many septate, and branched; the pseudoparaphyses anastomose in a gelatinous matrix. The asci measure 75–90 by 13–16 μm, with a short stalk; they are eight-spored (the spores are arranged in two or three parallel rows), cylindrical, bitunicate (two- layered), thick-walled, and lack any specialized apparatus at the tip.

If the aortic commissure has not previously been marked, the excised coronary arteries will be used to determine the implantation position of the aorta. The aorta is then transplanted onto the pulmonary root, using either absorbable or permanent continuous suture. The aortic clamp is temporarily removed while small sections of the neo-aorta are cut away to accommodate the coronary ostia, and a continuous absorbable suture is then used to anastomose each coronary "button" into the prepared space. In most cases, the coronary implantation sites will be at left and right anterior positions at the base of the neo-aorta; however, if the circumflex coronary artery branches from the right coronary artery, the circumflex coronary artery will be distorted if the pair are not implanted higher than normal on the neo- aorta, and in some cases they may need to be implanted above the aortic commissure, on the native aorta itself.

Datura innoxia is quite similar to D. metel, to the point of being confused with it in early scientific literature. D. metel is a closely related plant, believed until recently to be of Old World provenance (though now thought to have been brought to Asia from the Antilles no earlier than the sixteenth century) and misconstrued as being referred to in the works of Avicenna in eleventh century Persia. D. stramonium differs in having much smaller flowers, seed capsules dehisceing by four distinct valves, and dentate leaves, while the more closely related D. wrightii differs in having wider, 5-toothed (instead of 10-toothed) flowers which are usually pinkish-violet rather than white. D. innoxia differs from D. stramonium, D. metel & D. fastuosa in having about 7 to 10 secondary veins on either side of the midrib of the leaf which anastomose by arches at about 1 to 3 mm.

The post on the left is a tapered post, the one on the right is a parallel post In post and core fabrication, it is desirable that the post descends at least two-thirds of the length of root canal (or not less than the height of the crown) in order to provide sufficient retention. Width of post should be taken into account for maximum strength and resistance to fracture, however, it should not be too broad as this would lead to lateral perforation and root fracture. It is important to leave at least 4 mm-5 mm of gutta percha at the apex of the root canal, even at the expense of a longer post, because it is within the apical 4 mm of the root canal that the apical delta anastomose with the exterior surface of the root. Should these lateral canals not be blocked with the gutta percha and the cement used to place the gutta percha, the chances of microleakage and percolation of microbes are greatly increased, thereby increasing the likelihood of an endodontic failure.

It ascends between the sphenomandibular ligament and the lateral pterygoid muscle, and between the two roots of the auriculotemporal nerve to the foramen spinosum of the sphenoid bone, through which it enters the cranium; it then runs forward in a groove on the great wing of the sphenoid bone, and divides into two branches, anterior and posterior. The anterior branch, the larger, crosses the great wing of the sphenoid, reaches the groove, or canal, in the sphenoidal angle of the parietal bone, and then divides into branches that spread out between the dura mater and internal surface of the cranium, some passing upward as far as the vertex, and others backward to the occipital region. The posterior branch curves backward on the squamous part of the temporal bone, and, reaching the parietal bone some distance in front of its mastoid angle, divides into branches that supply the posterior part of the dura mater and cranium. The branches of the middle meningeal artery are distributed partly to the dura mater, but chiefly to the bones; they anastomose with the arteries of the opposite side, and with the anterior and posterior meningeal arteries.
