Within theauditory openings these nerves subdivide into cochlear and vestibularbranches, which are distributed to the internal ears (page 78). The nmth cranial nerves (or glosso-pharyngeal) appear on the surfaceof the restiform bodies, below the auditory nerves (Plate 6, Fig. 2, No. 20).The deep origins of these nerves are very close to those of the auditorynerves in the floor of the fourth ventricle. They make their exits fromthe cranium by means of the middle compartments of the jugular foramina,and are distributed to the mucous membrane of the phar
