Chorda tympani is a branch of the facial nerve that carries gustatory sensory innervation from the front of the tongue and parasympathetic (secretomotor) innervation to the submandibular and sublingual salivary glands.

Mar 20, 2024 · The chorda tympani is an intratemporal branch of the mastoid segment of the facial nerve (CN VII). It arises from the facial nerve within the facial canal of the temporal bone, traverses the middle ear and exits the skull through the petrotympanic fissure.

Jul 31, 2024 · The chorda tympani is a nerve that arises from the mastoid segment of the facial nerve, carrying afferent special sensation from the anterior two-thirds of the tongue via the lingual nerve, as well as efferent parasympathetic secretomotor innervation to the submandibular and sublingual glands.

Mar 4, 2023 · The chorda tympani leaves the intracranial space through the internal auditory canal with the seventh cranial nerve. Immediately after branching off the facial nerve, the chorda tympani runs through the posterior colliculus. It then travels through the middle ear and across the tympanic membrane.

Jan 18, 2025 · The chorda tympani is a branch of the facial nerve (cranial nerve VII) that plays a significant role in carrying taste sensations from the anterior two-thirds of the tongue as well as providing parasympathetic innervation to certain salivary glands.

Chorda tympani nerve testing is a specialized diagnostic procedure designed to evaluate the function of the chorda tympani nerve, a branch of the facial nerve (cranial nerve VII) that plays a key role in taste perception.

The Chorda Tympani Nerve is given off from the facial as it passes downward behind the tympanic cavity, about 6 mm. from the stylomastoid foramen.It runs upward and forward in a canal, and enters the tympanic cavity, through an aperture (iter chordæ posterius) on its posterior wall, close to the medial surface of the posterior border of the ...

The chorda tympani is a major branch of the facial nerve that originates in the facial canal of the temporal bone. Its preganglionic parasympathetic fibers have cell bodies located in the superior salivatory nucleus and those of its special sense taste …

The chorda tympani carries special sensory fibers from taste buds in the anterior 2/3 of the tongue and presynaptic parasympathetic fibers to the sublingual and submandibular glands along with the minor salivary glands. It separates from the main trunk of the facial nerve just before the latter passes out of the temporal bone through the ...

Chorda Tympani is a nerve that can be enlarged or repositioned during certain medical procedures, impacting the visualization of specific areas. If stretched to the point of partial tear, it is recommended to sever it completely to minimize taste disturbances in patients.
