Cerebellum - Superior view (English)

Isolated view of the cerebellum after it has been removed from the posterior cranial fossa and detached from the brainstem. The superior surface of the cerebellum is generally rounded and broad, except for pronounced anterior and posterior cerebellar notches located between the expanded cerebellar hemispheres. The anterior cerebellar notch contains the inferior colliculi of the midbrain in situ, while the posterior cerebellar notch contains the falx cerebelli. The primary fissure of the cerebellum separates the anterior and posterior lobes. The posterior superior fissure (a.k.a. postclival fissure) separates the posterior quadrangular lobule from the superior semilunar lobule. The largest and deepest fissure of the cerebellum, the horizontal fissure, extends posterolaterally along each hemisphere separating the superior and inferior semilunar lobules.
