The internal capsule is a white matter structure situated in the inferomedial part of each cerebral hemisphere of the brain. It carries information past the basal ganglia, separating the caudate nucleus and the thalamus from the putamen and the globus pallidus. The internal capsule contains both ascending and descending axons, going to and coming from the cerebral cortex. It also separates the caudate nucleus and the putamen in the dorsal striatum, a brain region involved in motor and reward pathways.
In the human body, the lateral thoracic artery is a blood vessel that supplies oxygenated blood to approximately one-third of the lateral structures of the thorax and breast.
The anterior choroidal artery is a bilaterally paired artery of the brain. It is typically a branch of the internal carotid artery which supplies the choroid plexus of lateral ventricle and third ventricle as well as numerous structures of the brain.
The right colic artery is an artery of the abdomen, a branch of the superior mesenteric artery supplying the ascending colon. It divides into two terminal branches - an ascending branch and a descending branch - which form anastomoses with the middle colic artery, and ileocolic artery (respectively).
The inferior alveolar artery is an artery of the head. It is a branch of the maxillary artery. It descends through the infratemporal fossa as part of a neurovascular bundle with the inferior alveolar nerve and vein to the mandibular foramen where it enters and passes anteriorly inside the mandible, supplying the body of mandible and the dental pulp of the lower molar and premolar teeth. Its terminal incisor branch supplies the rest of the lower teeth. Its mental branch exits the mandibula anteriorly through the mental foramen to supply adjacent lip and skin.
The ascending pharyngeal artery is an artery of the neck that supplies the pharynx.
The deep auricular artery is a branch of the maxillary artery. The deep auricular artery pierces the external acoustic meatus. It provides arterial supply to the skin of the external acoustic meatus, and contributes arterial supply to the tympanic membrane, and the temporomandibular joint.
The anterior tympanic artery is a branch of the maxillary artery. It passes through the petrotympanic fissure to entre the middle ear where it contributes to the formation of the circular anastomosis around the tympanic membrane. It provides arterial supply to part of the lining of the middle ear. It is accompanied by the chorda tympani nerve.
The infraorbital artery is a small artery in the head that arises from the maxillary artery and passes through the inferior orbital fissure to enter the orbit, then passes forward along the floor of the orbit, finally exiting the orbit through the infraorbital foramen to reach the face.
The posterior superior alveolar artery is a branch of the maxillary artery. It is one of two or three superior alveolar arteries. It provides arterial suply to the molar and premolar teeth, maxillary sinus and adjacent bone, and the gingiva.
The posterior meningeal artery is one of the meningeal branches of the ascending pharyngeal artery. It passes through the jugular foramen to enter the posterior cranial fossa. It is the largest vessel supplying the dura of the posterior cranial fossa.
The posterior commissure is a rounded band of white fibers crossing the middle line on the dorsal aspect of the rostral end of the cerebral aqueduct. It is important in the bilateral pupillary light reflex. It constitutes part of the epithalamus.
Medullary striae of fourth ventricle are a landmark of the rhomboid fossa - the floor of the fourth ventricle. They are part of the auditory system. The medullary striae are formed by crossed-over anterior internal arcuate fibers - efferents of the arcuate nucleus of medulla oblongata - as they pass laterally beneath the ependyma of the fourth ventricle to reach the contralateral cerebellum. The striae pass over the dorsal aspect of the medial vestibular nucleus.
The artery to the ductus deferens is an artery in males that provides blood to the ductus deferens.
The inferior cervical ganglion is one of the three cervical sympathetic ganglia. It is situated between the base of the transverse process of the last cervical vertebra and the neck of the first rib, on the medial side of the costocervical artery.
The posteromedial central arteries or paramedian arteries (also are branches of the posterior cerebral artery, and posterior communicating artery. They entering the substance of the brain through the posterior perforated substance. They supply a large portion of the diencephalon as well as some subcortical telencephalic structures.
The quadrigeminal cistern is a subarachnoid cistern situated between splenium of corpus callosum, and the superior surface of the cerebellum. It contains a part of the great cerebral vein, the posterior cerebral artery, quadrigeminal artery, glossopharyngeal nerve, and the pineal gland.
The anterolateral central arteries or lenticulostriate arteries are a group of small arteries mostly arising from the middle cerebral artery that enter the brain through the anterior perforated substance to provide arterial supply to parts of the basal ganglia. They are end arteries.
The thalamoperforating arteries are posteromedial central arteries which supply parts of the thalamus.
Posterolateral central arteries are arteries that arise from the posterior cerebral artery distal to its first - pre-communicating (P1) -segment. They are distributed to the cerebral peduncle, corpora quadrigemina, pineal gland, and the posterior portion of the thalamus.
