| 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) |
| commissura posterior cerebri | A thin band of white matter, crossing from side to side beneath the habenula of the pineal body and over the aditus ad aqueductum cerebri; it is largely composed of fibres interconnecting the left and right pretectal region and related cell groups of the midbrain; dorsally, it marks the junction of the diencephalon and mesencephalon. Synonym: posterior cerebral commissure. (05 Mar 2000) |
| commotio cerebri | Transient or prolonged unconsciousness with or without impairment of higher mental functions and/or brainstem functions, due to a violent blow to the head. (12 Dec 1998) |
| plexus arteriae cerebri anterioris | <anatomy, artery> An autonomic plexus accompanying the anterior cerebral artery, derived from the internal carotid plexus. Synonym: plexus arteriae cerebri anterioris. (05 Mar 2000) |
| plexus arteriae cerebri mediae | <anatomy, artery> An autonomic plexus accompanying the middle cerebral artery, derived from the internal carotid plexus. Synonym: plexus arteriae cerebri mediae. (05 Mar 2000) |
