Biventer lobule

Brain: Biventer lobule

Anterior view of the cerebellum.
Latin	lobulus biventer
Gray's	subject #187 790
NeuroNames	hier-667

The biventer lobule (or biventral lobule) is triangular in shape; its apex points backward, and is joined by the gray band to the pyramid.

The lateral border is separated from the inferior semilunar lobule by the postpyramidal fissure.

The base is directed forward, and is on a line with the anterior border of the tonsil, and is separated from the flocculus by the postnodular fissure.
