Location
The inferior ganglion of the glossopharyngeal nerve sits in the lower portion of the jugular foramen, just before the lower opening at the base of the skull.
The inferior ganglion of glossopharyngeal nerve is derived from epibranchial placode cells. These cells become sensory afferent neurons (Barlow, 2002).
Branches
The glossopharyngeal nerve runs into and out of the inferior ganglion. Typically, the tympanic nerve and the carotid branch of glossopharyngeal nerve will branch off at the level of the inferior ganglion.
Supplied Structures
All fibers of the glossopharyngeal nerve either originate in or pass through the inferior ganglion.
The cell bodies of the general and special visceral afferent fibers are located in the inferior ganglion. The general visceral afferent fibers carry information from the mucosal lining of the tympanic cavity, pharyngotympanic tube, oropharynx, carotid body, and carotid sinus. Special visceral afferent fibers carrying taste sensation from the posterior one third of the tongue.
