tympanic nerve


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. Synonym(s): nervus tympanicus [TA], Andersch nerve, Jacobson nerve

Andersch,

Carolus Samuel, German anatomist, 1732-1777. Andersch ganglion - the lower of two sensory ganglions on the glossopharyngeal nerve as it traverses the jugular foramen. Synonym(s): inferior ganglion of glossopharyngeal nerveAndersch nerve - Synonym(s): tympanic nerve

Jacobson,

Ludwig L., Danish anatomist, 1783-1843. Jacobson anastomosis - a portion of the tympanic plexus.Jacobson canal - a minute canal in the wedge of bone separating the jugular canal and carotid canal. Synonym(s): tympanic canaliculusJacobson cartilage - a narrow strip of cartilage located between the lower edge of the cartilage of the nasal septum and the vomer. Synonym(s): cartilago vomeronasalisJacobson nerve - Synonym(s): tympanic nerveJacobson organ - a fine vestigial horizontal canal ending in a blind pouch in the mucous membrane of the nasal septum. Synonym(s): vomeronasal organJacobson plexus - a plexus on the promontory of the labyrinthine wall of the tympanic cavity, formed by the tympanic nerve, an anastomotic branch of the facial nerve, and sympathetic branches from the internal carotid plexus. Synonym(s): tympanic plexusJacobson reflex - flexion of the fingers elicited by tapping the flexor tendons over the wrist joint or the lower end of the radius.
