5-11 Transverse section of the medulla through rostral portions of the hypoglossal nucleus and the middle portions of the principal olivary nucleus. The fourth ventricle has flared open at this level, and the resti-form body is enlarging to become a prominent structure on the dorsolateral aspect of the medulla.

Nucleus raphe, obscurus

Dorsal motor nucleus of the vagus

Posterior longitudinal fasciculus

Medial vestibular nucleus

Inferior (spinal) vestibular nucleus

Solitary nuclei and tract

Spinal trigeminal nucleus (pars interpolaris)

Accessory cuneate nucleus

Restiform body ( + Juxtarestiform body = Inferior cerebellar peduncle)
