534 NERYOUS SYSTEM. 



The inferior peduncles (processus ad medullam) connect the cerebellum with the 

 medulla oblongata. They pass downwards to the back part of the medulla, and 

 form part of the restiform bodies. Above, the fibres of each process are con- 

 nected chiefly with the laminae, on the upper surface of the cerebellum; and 

 below, they are connected with all three tracts of one half of the medulla, and, 

 through these, with the corresponding half of the cord, excepting the posterior 

 median columns. 



The middle peduncles (processus ad pontem), the largest of the three, connect 

 together the two hemispheres of the cerebellum, forming their great transverse 

 commissure. They consist of a mass of curved fibres, which arise in the lateral 

 parts of the cerebellum, and pass across to the same points on the opposite side. 

 They form the transverse fibres of the pons Varolii.

 ous Centres," in the Cyclop, of Anat. and Physiol. For further information on the Descriptive
