Serebellum

It's related with muscle motor function. If the serebellum is removed surgically, cordinated muscle contraction is disturbed and maintanence of body posture disappear. The serebellar structure is similar to the cortex cerebri. There are gray matter on the surface but white matter in the inner side. The surface have many small invagination that is called as gyri as like cerebri. Serebellum receives impulses from the perphery by the sipinocerebellar tract and from some nuclei from brain stem and also fibers from motor cortex.
