The accompanying illustrationshows sufficiently their anatomical seats without entering into a detaileddescription (Fig. 15). Sections of the medulla also show the seat of the three pairs ofcerebellar peduncles and their relation to the restiform bodies,which are the continuation of the postero-lateral tracts of the cord andto the pons, which can be considered as a continuation of the middlecerebellar peduncles.

(Morris Anatomy.)The plane of the section is obliquely transverse or parallel with the direction of the brachia pontis. Sections of the Pons show the passage between its deep and super-ficial fibers of the longitudinal pyramidal fasciculi, which are the con-tinuation of the cerebral peduncles (crura) and which at the lower borderof the pons emerge as pyramids proper. These fibers are situated in theventral portion of the pons. In its dorsal portion (tegmentum) the struc-tures are continuous with those of the medulla below (Fig. 16). The pons also contains separate aggregations of gray matter, calledNuclei pontis. They are dispersed between the pontine and pyramidal 20 THE CENTRAL NERVOUS SYSTEM fibers.
