Cerebellum - Superior view (Latin)

Isolated view of the cerebellum after it has been removed from the fossa posterior cranii and detached from the brainstem. The surface of the cerebellum is much more tightly folded compared to the cerebral cortex and is marked with fine, leaflike gyri known as folia. Grossly, the cerebrum is built around a central vermis which is flanked on either side by a hemispherium cerebelli. The facies superior cerebelli is generally rounded and broad, except for two pronounced incisurae between the expanded hemispheria cerebelli. The incisura anterior cerebelli contains the colliculi inferiores of the midbrain(mesencephalon), while the incisura posterior cerebei contains the falx cerebelli. The fissura prima cerebelli separates the lobus anterior from the lobus posterior. The fissura posterior superior (a.k.a. fissura postclivalis) separates the lobulus quadrangularis posterior from the lobulus semilunaris superior. The largest and deepest fissure of the cerebellum, the fissura horizontalis, extends posterolaterally along each hemispherium separating the lobuli semilunares superior/inferior.
