The ganglion of the glossopharyngeal nerve (CN IX) is:
Show answer and explanation
Correct answer: B. Otic ganglion
- A. The trigeminal ganglion (Gasserian/semilunar ganglion) is the sensory ganglion for CN V — not CN IX.
- B. The OTIC GANGLION is the parasympathetic ganglion associated with CN IX (glossopharyngeal nerve). It receives preganglionic fibers from the inferior salivatory nucleus via the tympanic branch of CN IX (Jacobson's nerve) and the lesser petrosal nerve. Postganglionic fibers travel via the auriculotemporal nerve to innervate the PAROTID GLAND.
- C. The geniculate ganglion is the sensory ganglion for CN VII (facial nerve) — it contains cell bodies for taste from the anterior 2/3 tongue (via chorda tympani) and ear sensation.
- D. The pterygopalatine ganglion is associated with CN VII (facial nerve) via the greater petrosal nerve — it innervates the lacrimal, nasal, and palatine glands.
