The tympanic nerve (nerve of Jacobson) is a branch of the glossopharyngeal nerve found near the ear.

Path
It arises from the petrous ganglion, and ascends to the tympanic cavity through a small canal, the inferior tympanic canaliculus, on the under surface of the petrous portion of the temporal bone on the ridge which separates the carotid canal from the jugular fossa.
In the tympanic cavity it divides into branches which form the tympanic plexus and are contained in grooves upon the surface of the promontory.
Jacobson's nerve contains both sensory and secretory fibers.
- Sensory fibers supply the middle ear.
- Parasympathetic secretory fibers continue as the Lesser Petrosal nerve and provide secretomotor innervation to the parotid gland. The secretory fibers enter the otic ganglion.
- Sympathetic fibers (for the large deep petrosal nerve) through communication with the carotid plexus
The postganglionic parasympathetic fibers are then distributed via the auriculotemporal nerve (branch of the trigeminal nerve) to the parotid gland.
Clinical significance
This nerve may be involved by paraganglioma, in this location referred to as glomus jugulare or glomus tympanicum tumours.

- 舌咽神経から分岐し、頚動脈管の後部にある鼓室神経小管に入る。鼓室の岬角で鼓室神経叢を作り、粘膜に分布する。その後、鼓室神経は鼓室の壁を貫いて内頭蓋底に達して小錐体神経となる。
