| OTS | occipital temporal sulcus; orotracheal suction |
|---|---|
| RoS | rostral sulcus |
| 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) |
| venae cerebri inferiores | Numerous cerebral veins that drain the undersurface of the cerebral hemispheres and empty into the cavernous and transverse sinuses. Synonym: venae cerebri inferiores. (05 Mar 2000) |
| venae cerebri internae | Paired veins passing caudally near the midline in the tela choroidea of the third ventricle, formed by the union of the choroid vein, thalamostriate (terminal) vein, and vein of septum pellucidum, and uniting caudally so as to form the great cerebral vein. Synonym: venae cerebri internae, veins of Galen. (05 Mar 2000) |
| venae cerebri profundae | The numerous veins draining the deep structures of the cerebral hemispheres; they empty into the tributaries of the great cerebral vein. Synonym: venae cerebri profundae. (05 Mar 2000) |
| venae cerebri superficiales | The veins on the superficial surface of the cerebral hemispheres; they comprise three groups: superior, middle, and inferior. Synonym: venae cerebri superficiales. (05 Mar 2000) |
| 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 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 |
