Biventer lobule

From Wikipedia, the free encyclopedia

Brain: Biventer lobule
Under surface of the cerebellum.
Gray's	subject #187 790

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.
