Cerebellar hemisphere
The cerebellum consists of three parts, a median and two lateral, which are continuous with each other, and are substantially the same in structure.The median portion is constricted, and is called the vermis, from its annulated appearance which it owes to the transverse ridges and furrows upon it; the lateral expanded portions are named the hemispheres.This article incorporates text in the public domain from page 788 of the 20th edition of Gray's Anatomy (1918) 2° (Spinomesencephalic tract → Superior colliculus of Midbrain tectum)This neuroanatomy article is a stub.You can help Wikipedia by expanding it.
