What is the auriculotemporal nerve?
The auriculotemporal nerve is a tributary of the mandibular division of cranial nerve five, the trigeminal nerve. It contains sensory, vasomotor, and parasympathetic fibers.
Where does the auriculotemporal nerve innervate?
The auriculotemporal nerve innervates the skin behind the temporomandibular joint and within the superior surface of the parotid gland. It has a course along a temporalis superficialis and innervates the tragus and part of the adjoining auricle of the ear and the posterior part of the temple.

Where is the trigeminal nerve?
The trigeminal nerve is one set of the cranial nerves in the head. It is the nerve responsible for providing sensation to the face. One trigeminal nerve runs to the right side of the head, while the other runs to the left.
What causes Auriculotemporal neuralgia?
Tenderness over the auriculotemporal nerve has been described, and the neuralgia can be triggered by pressure on the preauricular region. Local anesthetic blockade can completely resolve all these symptoms [ 1–4 ]. The auriculotemporal nerve is terminal branch of the trigeminal nerve.
Which is the source of the Zygomaticotemporal nerve?
The zygomaticotemporal nerve, arising from the maxillary division of the trigeminal nerve, innervates the skin of the temple region. The auriculotemporal nerve, derived from the mandibular division of the trigeminal nerve, innervates the posterior portion of the skin of the temple.
Is auriculotemporal nerve a branch of facial nerve?
The auriculotemporal nerve is a branch of the mandibular nerve that provides sensation to several regions on the side of your head, including the jaw, ear, and scalp. For much of its course through the structures of your head and face, it runs along the superficial temporal artery and vein.
What causes auriculotemporal neuralgia?
Is auriculotemporal nerve part of cervical plexus?
Nerves of the auricle the auriculotemporal nerve that supplies the tragus, crux and the ascending helix. the auricular branch of the superficial cervical plexus that supplies the lobe, and both posterior parts of the helix and the antihelix.
What are the 3 trigeminal nerves?
It contains the sensory cell bodies of the 3 branches of the trigeminal nerve (the ophthalmic, mandibular, and maxillary divisions).
What are the symptoms of Auriculotemporal neuralgia?
Auriculotemporal neuralgia (ATN) is an infrequent form of facial pain. It is strictly unilateral and side-locked, perceived mainly in the temporal scalp, temporomandibular joint, parotid and auricular regions. Intensity ranges from moderate to severe and usually associates paroxysmal exacerbations of stabbing pain.
What does the auriculotemporal nerve affect?
What is zygomaticotemporal?
The zygomaticotemporal nerve (zygomaticotemporal branch, temporal branch) is a small nerve of the face. It is derived from the zygomatic nerve, a branch of the maxillary nerve (CN V2). It is distributed to the skin of the side of the forehead.
Is the auriculotemporal nerve a motor?
Secretory-Motor Function The single motor function of the auriculotemporal nerve’s inferior branch deals with the parotid gland. The nerve allows the gland to secrete saliva, which is where the term secretory-motor comes from.
Is auriculotemporal nerve superficial?
The auriculotemporal nerve. The auricular nerve can be accessed through the temporalis muscle. The nerve fibers can be located in the posterior superficial aspect of the muscle.
What nerve is between C3 and C4?
The supraclavicular nerve, of C3 and C4, descends from the posterior sternocleidomastoid and provides sensory information from the skin over the clavicle and shoulder.
Are there two trigeminal nerves?
The trigeminal nerve, also called the cranial nerve V (that’s the Roman numeral five), is the fifth of 12 cranial nerves. You have two trigeminal nerves, one on each side of your body. They start in your brain and travel throughout your head.
What does the trigeminal nerve control?
The trigeminal nerve is the largest of the 12 cranial nerves. Its main function is transmitting sensory information to the skin, sinuses, and mucous membranes in the face. The nerve communicates touch, pain, and temperature to the brain. It also stimulates movement in the jaw muscles.
