E, The temporal lobe has been elevated to show a group of veins that pass from the lower surface of the cerebral hemisphere to the tentorial sinuses. Two large lateral cerebral veins empty into the right transverse sinus, but the more medial veins exposed by eliminating the temporal lobe empty into tentorial sinuses. F, The posterior part of the right temporal lobe has been elevated to show the complex of veins on the inferior surface of the hemisphere that empty into the tentorial sinuses. G, The right half of the tentorium has been opened while preserving a large tentorial sinus, which receives drainage from the cerebrum and cerebellum. The temporal and occipital lobes have been preserved on the left side. H, The posterior lip of the cerebellomesencephalic fissure has been removed. The paired veins of the superior cerebellar peduncle ascend to join and form the vein of the cerebellomesencephalic fissure, which empties into the vein of Galen. (Images courtesy of AL Rhoton, Jr.)
