Glossopharyngeal nerve (origin and proximal branches) (English)

The glossopharyngeal nerve (CN IX) carries motor fibers from the inferior salivatory nucleus (general visceral efferent) and nucleus ambiguus (general somatic efferent fibers), and sensory fibers from the spinal trigeminal nucleus (general somatic afferent) and solitary nucleus (general visceral sensory).The CN IX emerges from the lateral aspect of the rostral medulla and leaves the skull via the anterior part of the jugular foramen. Here, CN IX bears its associated sensory ganglia: the superior and inferior ganglia.
