| hemispherium cerebri | 1. A half sphere; one half of a sphere or globe, when divided by a plane passing through its center. 2. Half of the terrestrial globe, or a projection of the same in a map or picture. 3. The people who inhabit a hemisphere. "He died . . . Mourned by a hemisphere." (J. P. Peters)ten Cerebral hemispheres. <anatomy> See Brain. <physics> Magdeburg hemispheres, two hemispherical cups forming, when placed together, a cavity from which the air can be withdrawn by an air pump; used to illustrate the pressure of the air. So called because invented by Otto von Guericke at Magdeburg. Origin: L. Hemisphaerium, Gr.; half = sphere: cf. F. Hemisphere. See Hemi-, and Sphere. Source: Websters Dictionary (01 Mar 1998) |

| hemispherium cerebelli | The large part of the cerebellum lateral to the vermis cerebelli. Synonym: hemispherium cerebelli, hemispherium. (05 Mar 2000) |
| aditus ad aqueductum cerebri | Entrance to the cerebral aqueduct (of Sylvius) from the caudal part of the third ventricle. Synonym: aditus ad aqueductum cerebri, Bartholin's anus, opening to cerebral aqueduct. (05 Mar 2000) |
| anus cerebri | Entrance to the cerebral aqueduct (of Sylvius) from the caudal part of the third ventricle. Synonym: aditus ad aqueductum cerebri, Bartholin's anus, opening to cerebral aqueduct. (05 Mar 2000) |
| aqueductus cerebri | An ependymal-lined canal in the mesencephalon about 20 mm long, connecting the third to the fourth ventricle. Synonym: aqueductus cerebri, aqueduct of cerebrum, aqueductus sylvii, iter a tertio ad quartum ventriculum, sylvian aqueduct. (05 Mar 2000) |
| arteria cerebri anterior | <anatomy, artery> One of the two terminal branches (with middle cerebral artery) of the internal carotid; it passes anterior, loops around the genu of the corpus callosum then posteriorly in the interhemispheric fissure along with its fellow of the opposite side, the two being joined by the anterior communicating artery; for descriptive purposes it is divided into two parts: the precommunical part (A2 segment of clinical terminology), supplying branches to the thalamus and corpus striatum, and the postcommunical part, (A2) or pericallosal artery, supplying branches to the cortex of the medial parts of the frontal and parietal lobes. Synonym: arteria cerebri anterior. (05 Mar 2000) |
| arteria cerebri media | <anatomy, artery> One of the two large terminal branches (with anterior cerebral artery) of the internal carotid artery; it passes laterally around the pole of the temporal lobe, then posteriorly in the depth of the lateral cerebral fissure; for descriptive purposes it is divided into three parts: 1) the sphenoidal part (M1 segment of clinical terminology), supplying perforating branches to the internal capsule, thalamus, and striate body; 2) the insular part, supplying branches to the insula and adjacent cortical areas; and 3) the terminal part or cortical part, supplying a large part of the central cortical convexity (the latter two collectively forming M2 segment). Synonym: arteria cerebri media. (05 Mar 2000) |
| arteria cerebri posterior | <anatomy, artery> Formed by the bifurcation of the basilar artery; it passes around the cerebral peduncle to reach the medial aspect of the hemisphere; for descriptive purposes it is divided into three parts: 1) the precommunical part (P1 segment of clinical terminology), the part before the junction with the posterior communicating artery, supplying parts of the thalamus, hypothalamus, and midbrain; 2) the postcommunical part (P2), supplying the thalamus, cerebral peduncles, and the choroid plexuses of the lateral and third ventricles; and 3) the terminal or cortical part, supplying the cortex of the temporal (P3) and occipital (P4) lobes. Synonym: arteria cerebri posterior. (05 Mar 2000) |
| astrocytosis cerebri | A diffuse intracranial neoplasm of astrocytic origin. Synonym: astrocytosis cerebri, glioblastosis cerebri. (05 Mar 2000) |
| basis cerebri | The inferior surface of the brain visible when seen from below. Synonym: facies inferior cerebri, basis cerebri, inferior cerebral surface. (05 Mar 2000) |
| 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) |
