superior medullary velum
http://purl.obolibrary.org/obo/UBERON_0002659

The superior medullary velum (anterior medullary velum, valve of Vieussens) is a thin, transparent of white substance, which stretches between the superior cerebellar peduncles; on the dorsal surface of its lower half the folia and lingula are prolonged. It forms, together with the superior cerebellar peduncle, the roof of the upper part of the fourth ventricle; it is narrow above, where it passes beneath the inferior colliculi, and broader below, where it is continuous with the white substance of the superior vermis. A slightly elevated ridge, the fraenulum veli, descends upon its upper part from between the inferior colliculi, and on either side of this the trochlear nerve emerges. Blood is supplied by branches from the superior cerebellar artery. [WP,unvetted].
