| cerebral ventricle neoplasms | Neoplasms located in the brain ventricles including the two lateral, third, and fourth ventricles. (12 Dec 1998) |
| cerebral ventricles | See: lateral ventricle, fourth ventricle, third ventricle, cavity of septum pellucidum. (05 Mar 2000) |
| cerebral ventriculography | Radiography of the ventricular system of the brain after injection of air or other contrast medium directly into the cerebral ventricles. It is used also for X-ray computed tomography of the cerebral ventricles. (12 Dec 1998) |
| cerebral vesicle | Each of the three divisions of the early embryonic brain (prosencephalon, mesencephalon, and rhombencephalon). Synonym: encephalic vesicle, primary brain vesicle. (05 Mar 2000) |
| cerebral vomiting | Vomiting due to intracranial disease, especially elevated intracranial pressure. (05 Mar 2000) |
| granular layers of cerebral cortex | Layers 2 (outer) and 4 (inner) of the cortex cerebri. (05 Mar 2000) |
| great cerebral vein | 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) |
| great cerebral vein of Galen | 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) |
| middle cerebral artery | <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) |
| cistern of great cerebral vein | <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) |
| molecular layer of cerebral cortex | Layer 1 of the cortex cerebri. Synonym: plexiform layer of cerebral cortex. (05 Mar 2000) |
| commissure of cerebral hemispheres | <anatomy> A great commissure (connection) between the two cerebral hemispheres (right and left). (13 Nov 1997) |
| congenital cerebral aneurysm | Localised dilation of a cerebral vessel; usually a berry aneurysm. (05 Mar 2000) |
| plexiform layer of cerebral cortex | Layer 1 of the cortex cerebri. Synonym: plexiform layer of cerebral cortex. (05 Mar 2000) |
