| 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) |
|---|---|
| margo inferior cerebri | The irregular, discontinuous margin of the cerebral hemisphere at the junction of the inferior and superolateral surfaces. Synonym: margo inferolateralis, inferolateral margin. (05 Mar 2000) |
| margo medialis cerebri | The irregular border of the cerebral hemisphere at the junction of the inferior and medial surfaces. Synonym: margo inferomedialis, inferomedial margin. (05 Mar 2000) |
| margo superior cerebri | The curved margin of the cerebral hemisphere at the junction of the superolateral and medial surfaces. Synonym: margo superomedialis, superomedial margin. (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) |
| 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) |
| cisterna venae magnae cerebri | <anatomy, vein> An expansion of the subarachnoid space extending forward between the corpus callosum and the thalamus; it encloses the internal cerebral veins which caudally join to form the vena magna cerebri (Galen's vein). Synonym: ambient cistern, Bichat's canal, Bichat's foramen, cistern of great vein of cerebrum, cisterna ambiens, cisterna superioris, cisterna venae magnae cerebri, superior cistern. (05 Mar 2000) |
