Fig. 4From: “Unforgettable” – a pictorial essay on anatomy and pathology of the hippocampusArterial supply of the hippocampal head. B = basal Rosenthal vein, 1 = temporal horn of the lateral ventricle, 2 = uncal recess of the lateral ventricle, 3 = hippocampal digitations, 4 = uncal sulcus. Both the anterior hippocampal artery, originating from the trunk or branches of the posterior cerebral artery, and the uncal branch of the anterior choroidal artery, dive into the uncal sulcus at the level of the hippocampal head and form anastomoses in the sulci between the hippocampal digitations. Here, only one of both arteries in the uncal sulcus is drawnBack to article page
