tympanic nerve

(redirected from Tympanic branch)

tym·pan·ic nerve

[TA]
a nerve from the inferior ganglion of the glossopharyngeal nerve, passing through the tympanic canaliculus to the tympanic cavity, forming there the tympanic plexus that supplies the mucous membrane of the tympanic cavity, mastoid cells, and auditory tube; presynaptic parasympathetic fibers also pass through the tympanic nerve via the lesser superficial petrosal nerve to the otic ganglion, where they synapse with postsynaptic fibers that continue to supply the parotid gland.
