The tympanic nerve (Jacobson's nerve) is a branch of the glossopharyngeal nerve passing through the petrous part of the temporal bone to reach the middle ear.It provides sensory innervation for the middle ear, the Eustachian tube, the parotid gland, and mastoid cells.
In the temporal part of the facial canal, the nerve gives branch to the stapedius muscle and chorda tympani. The chorda tympani supplies taste fibers to the anterior two thirds of the tongue, and also synapses with the submandibular ganglion. Postsynaptic fibers from the submandibular ganglion supply the sublingual and submandibular glands.
Before the nerve exits the skull via the stylomastoid foramen and after the nerve to the stapedius muscle has branched off, the facial nerve gives off the chorda tympani nerve. This nerve exits the skull through the petrotympanic fissure and merges with the lingual nerve , after which it synapses with neurons in the submandibular ganglion .

A branch of cranial nerve VII, the chorda tympani, runs through the fissure to join with the lingual nerve providing special sensory (taste) innervation to the tongue. Anterior tympanic artery and tympanic veins also pass through the structure.
Preganglionic fibers en route to the pterygopalatine ganglion (destined to ultimately innervate the lacrimal gland and the mucosal glands of the nose, palate, and pharynx) subsequently form the greater petrosal nerve, whereas those en route to the submandibular ganglion (destined to ultimately innervate the submandibular and sublingual salivary glands) subsequently form the chorda tympani.
