Posterior Perspective of the Gross Cerebellum

Surgical Correlation


Posterior Perspective of the Gross Cerebellum. The cerebellum can be divided anatomically into anterior, posterior, and flocculonodular lobes.  The anterior and posterior lobes are seen here, separated by the primary (preclival) fissure.  Rostrally, the cerebellar hemisphere contains the quadrangular lobule, which is divided into an anterior and posterior portion by the primary fissure. The superior posterior (postlunate) fissure divides the posterior quadrangular lobule (also referred to as the simple lobule) from the superior semilunar lobule. The superior semilunar lobule is separated from the inferior semilunar lobule by the horizontal fissure. (Image courtesy of AL Rhoton, Jr.)
