| venae cerebri internae | Paired veins passing caudally near the midline in the tela choroidea of the third ventricle, formed by the union of the choroid vein, thalamostriate (terminal) vein, and vein of septum pellucidum, and uniting caudally so as to form the great cerebral vein. Synonym: venae cerebri internae, veins of Galen. (05 Mar 2000) |
|---|---|
| venae cerebri profundae | The numerous veins draining the deep structures of the cerebral hemispheres; they empty into the tributaries of the great cerebral vein. Synonym: venae cerebri profundae. (05 Mar 2000) |
| venae cerebri superficiales | The veins on the superficial surface of the cerebral hemispheres; they comprise three groups: superior, middle, and inferior. Synonym: venae cerebri superficiales. (05 Mar 2000) |
| venae cerebri superiores | Numerous (8 to 10) veins that drain the dorsal convexity of the cortical hemisphere and empty into the superior sagittal sinus, curving rostrally in passing through the subdural space so as to enter the sinus at an acute forward angle. Synonym: venae cerebri superiores. (05 Mar 2000) |
| pars anterior commissurae anterioris cerebri | The anterior part of the anterior or rostral commissure of the brain. Synonym: pars anterior commissurae rostralis, pars anterior commissurae anterioris cerebri. (05 Mar 2000) |
| pars postcommunicalis arteria cerebri anterior | <anatomy, artery> The continuation of the anterior cerebral artery after the anterior communicating artery; it supplies branches to the cerebral cortex as it passes along the corpus callosum. Synonym: pars postcommunicalis arteria cerebri anterior, arteria pericallosa, postcommunical part of anterior cerebral artery. (05 Mar 2000) |
| pars precommunicalis arteriae cerebri anterior | pars precommunicalis arteriae cerebri anterior |
| glioblastosis cerebri | A diffuse intracranial neoplasm of astrocytic origin. Synonym: astrocytosis cerebri, glioblastosis cerebri. (05 Mar 2000) |
| gliomatosis cerebri | A diffuse intracranial neoplasm of astrocytic origin. Synonym: astrocytosis cerebri, glioblastosis cerebri. (05 Mar 2000) |
| medial sulcus of crus cerebri | A groove in the lateral wall of the interpeduncular fossa of the midbrain from which the rootlets of the oculomotor nerve emerge. Synonym: sulcus medialis cruris cerebri, sulcus nervi oculomotorii, sulcus of the oculomotor nerve. (05 Mar 2000) |
| pedunculus cerebri | Originally denoting either of the two halves of the midbrain (a relatively narrow "neck" connecting the forebrain to the hindbrain); this term has been variably used to designate only those large bundles of corticofugal fibres forming the crus cerebri, or to designate the crus cerebri plus the midbrain tegmentum; this latter more inclusive usage (crus cerebri and midbrain tegmentum) is preferred; the substantia nigra, while a part of the base of the peduncle (basis pedunculi), is considered a structure separating the midbrain tegmentum from the crus cerebri. See: crus cerebri. Synonym: pedunculus cerebri. (05 Mar 2000) |
| cerebri- | See: cerebro-. (05 Mar 2000) |
| membrana cerebri | Any one of the cerebral meninges. (05 Mar 2000) |
| circulus arteriosus cerebri | An anastomotic "circle" of arteries (roughly pentagonal in outline) at the base of the brain, formed, sequentially and in anterior to posterior direction, by the anterior communicating artery, the two anterior cerebral, the two internal carotid, the two posterior communicating, and the two posterior cerebral arteries. Synonym: circulus arteriosus cerebri, circle of Willis. (05 Mar 2000) |
| cisterna fossae lateralis cerebri | An elongated expansion of the subarachnoid space where the arachnoid bridges over the opening of the Sylvian fissure. Synonym: cisterna fossae lateralis cerebri. (05 Mar 2000) |
