| ramus posterior sulci lateralis cerebri | The long, posteriorly-directed continuation of the lateral cerebral sulcus which extends between the temporal lobe inferiorly and the parietal lobe superiorly, its termination surrounded by the supramarginal gyrus. Synonym: ramus posterior sulci lateralis cerebri. (05 Mar 2000) |

| vena cerebri anterior | <anatomy, vein> A small vein that parallels the anterior cerebral artery and drains into the basal vein. Synonym: vena cerebri anterior. (05 Mar 2000) |
| vena cerebri magna | A large, unpaired vein formed by the junction of the two internal cerebral veins in the caudal part of the tela choroidea of the third ventricle; it passes caudally between the splenium of the corpus callosum and the pineal gland, curving dorsally to merge with the inferior sagittal sinus to form the straight sinus. Synonym: vena cerebri magna, great cerebral vein, great vein of Galen. (05 Mar 2000) |
| vena cerebri media profunda | <anatomy, vein> The vein that accompanies the middle cerebral artery in the depths of the lateral sulcus and empties into the basal vein of Rosenthal. Synonym: vena cerebri media profunda. (05 Mar 2000) |
| vena cerebri media superficialis | <anatomy, vein> A large vein passing along the line of the sylvian fissure to join the cavernous sinus; it communicates with the superior sagittal sinus and transverse sinus via the superior and inferior anastomotic veins, respectively. Synonym: vena cerebri media superficialis. (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) |
| 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) |
