Outline sketch of a section of the cerebellum, showing the corpus dentatum. The section has been carried through the left lateral part of the pons, so as to divide the superior peduncle and pass nearly through the middle of the left cerebellar hemisphere. The olivary body has also been divided longitudinally so as to expose in section its corpus dentatum. c r, crus cerebri; f, fillet; q, corpora quadrigemina; s p, superior peduncle of the cerebellum divided; m p, middle peduncle or lateral part of the pons Varolii, with fibers passing from it into the white stem; a v, continuation of the white stem radiating towards the arbor vitae of the folia; c d, corpus dentatum; o, olivary body with its corpus dentatum; p, anterior pyramid.
