Brain: Frenulum of superior medullary vellum
Hind- and mid-brains; postero-lateral view. (Frenulum veli labeled at center left.)
Latin	frenulum veli medullaris superioris
Gray's	subject #188 805
NeuroNames	ancil-323

The frenulum veli, or frenulum of superior medullary velum, also known as the frenulum veli medullaris superioris, cerebellar frenulum, or frenulum cerebelli is a slightly raised white band passing from the inferior end of the medial longitudinal fissure, through the groove between the quadrigeminal bodies, and down to the superior medullary velum.

On either side of this band the trochlear nerve emerges, and passes forward on the lateral aspect of the cerebral peduncle to reach the base of the brain.
