=====Biventer lobule===== The biventer lobule (or biventral lobule) is a region of the [[cerebellum]]. It 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]]. {{http://www.3dneuroanatomy.com/wp-content/uploads/2013/03/tva9.jpg}} http://www.3dneuroanatomy.com/wp-content/uploads/2013/03/tva9.jpg bvl: biventral lobule; cmf: [[cerebellomedullary fissure]] Ivv: [[inferior vermin vein]]; pci: posterior cerebellar incisura; T: tonsil; V: vallecula; M: medulla.
