Ves.R, Vestibular root of eighth nerve sending fibers to C.B (cerebrum) and 

 C.B.L (cerebellum) downwards to center in medulla oblongata (Med), and to 

 Deiters's nucleus (N.Deit), from which fibers pass to oculo-motor mechanism 

 (N.Vi) and to center in the anterior horn of the spinal cord. 



is connected with the vestibulo-spinal tract which runs down the cord 

 to the anterior horns. Fibers from the cerebellar nuclei go by the 

 superior cerebellar peduncle and the red nucleus, and end in the
