Cerebellum[✎ edit | edit source]

  • In the posterior cranial fossa you can find the Cerebellum (2).
  • Cerebellum is quite similar to the cerebrum when it comes to its looks, its surface is highly folded, but is smaller than the cerebrum (1). The function of the cerebellum is to regulate muscle tone, coordination and fine movement. It has three lobes, flocculonodular lobe, anterior lobe of the cerebellar body and posterior lobe of the cerebellar body (3).
Cerebellar cortex[✎ edit | edit source]
  • The outer cover is called cortex and is made of gray matter, the inner part i made by white matter (2). The cortex of cerebellum is divided into three layers: molecular layer, purkinje cell layer and granular layer (2,3).
  • Molecular layer: Have stellate cells and basket cells. (2,3)
  • Purkinje layer: As the name imply this layer consists of Purkinje cells, which are large flask-shaped cells, and it also contains Golgi type I neurons.(2,3)
  • Granular layer: This layer consists of small neurons that are densly packed, called Granule cells, and Golgi cells (2,3).
Cells in Cerebellum[✎ edit | edit source]
  • Purkinje cells
  • Granule cells
  • Mossy fibers
  • Climbing fibers
