| posterior cerebral commissure | 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) |

| superficial cerebral veins | 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) |
| superficial middle cerebral vein | <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) |
| superior cerebral veins | 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) |
| deep cerebral veins | 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) |
| deep middle cerebral vein | <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) |
