Medical Definition of Tympanic nerve

1. A nerve from the inferior ganglion of the glossopharyngeal nerve, passing through the tympanic canaliculus to the tympanic cavity, forming there the tympanic plexus which supplies the mucous membrane of the tympanic cavity, mastoid cells, and auditory tube; presynaptic parasympathetic fibres also pass through the tympanic nerve via the lesser superficial petrosal nerve to the otic ganglion, where they synapse with postsynaptic fibres that continue to supply the parotid gland. Synonym: nervus tympanicus, Andersch's nerve, Jacobson's nerve. (05 Mar 2000)
