Which autonomic ganglion is associated with CN IX?

Glossopharyngeal (CN IX) carries preganglionic parasympathetic fibers that originate in the inferior salivatory nucleus and travel with the tympanic nerve, forming the tympanic plexus, then the lesser petrosal nerve to synapse in the otic ganglion. The otic ganglion sits just medial to the mandibular nerve in the infratemporal fossa. Postganglionic fibers hitchhike on the auriculotemporal branch of V3 to the parotid gland, stimulating salivation. The other ganglia listed are linked to different nerves: the submandibular ganglion with CN VII (via chorda tympani), the pterygopalatine ganglion with CN VII (via greater petrosal), and the ciliary ganglion with CN III.
