Is auriculotemporal nerve motor or sensory?
The auriculotemporal nerve is a branch of the mandibular nerve (V3) that runs with the superficial temporal artery and vein, and provides sensory innervation to various regions on the side of the head.
What does auriculotemporal nerve innervate?
The auriculotemporal nerve has five main branches. These are the anterior auricular, articular, parotid, superficial temporal, and also branches to the external auditory meatus. The anterior auricular branches innervate the skin overlying the tragus, as well as the adjacent part of the helix.
Which of the following is supplied by the auriculotemporal nerve?
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. the vagus nerve anastomosed with the facial nerve that supplies the concha (Ramsay Hunt’s zone).
What does lingual nerve innervate?
The Lingual nerve (LN) is a branch of the mandibular division of the trigeminal nerve (V3) that is responsible for general somatic afferent (sensory) innervation. It supplies the mucous membranes of the mandibular lingual gingiva, floor of the mouth and the ipsilateral two-thirds of the tongue.
What is function of auriculotemporal 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 does Auriculotemporal mean?
: the branch of the mandibular nerve that supplies sensory fibers to the skin of the external ear and temporal region and autonomic fibers from the otic ganglion to the parotid gland.
Where does auriculotemporal nerve come from?
The auriculotemporal nerve contains secretomotor, somatosensory, and vasomotor fibers. This nerve originates from the sensory nucleus of the trigeminal nerve in the pons. The mandibular branch of the trigeminal nerve exits the cranium out of the foramen ovale.
Where does the lingual nerve travel?
Another variation is the distance the lingual nerve travels in the floor of the mouth before turning medially toward the tongue. Most lingual nerves are found to deviate toward the tongue from the floor of the mouth between the mesial of the first molar and the distal of the second molar.
Where is the auriculotemporal nerve located?
How do you give an auriculotemporal nerve block?
The auriculotemporal nerve can be blocked by injecting local anesthetic solution above the posterior portion of the zygoma, anterior to the ear and behind the superficial temporal artery. The needle (27 gauge) is inserted anterior and superior to the tragus.
Is the lingual nerve a sensory nerve?
The lingual nerve is one of the sensory branches of the mandibular division of the trigeminal nerve. [5] It contains general somatic afferent nerve fibers and, after chorda tympani joins it, also carries general visceral efferent nerve fibers and special visceral afferent fibers.
Where does the auriculotemporal nerve supply sensation?
The auriculotemporal nerve is a branch of the mandibular division of the trigeminal nerve and supplies sensation to the tragus and helical crus. The anterior branch of the greater auricular nerve (from the cervical plexus) innervates most of the ear, including the helix, scapha, antihelix, concha,…
What to do if auriculotemporal nerve is removed?
The standard treatment is the injection of botulinum toxin. 7 Surgical removal of the parotid gland can result in a complication called Frey syndrome. After the gland is gone from the cheek, the auriculotemporal nerve’s parotid branch sometimes attaches itself to the sweat glands in the same area.
Where does the greater auricular nerve supply the tragus?
The greater auricular nerve (GAN) supplies the main innervation to the anterior portion of the external ear. The auriculotemporal nerve (ATN) also supplies the tragus and helical crus regions while the mastoid branch of the lesser occipital nerve (LON) supplies innervation to most of the posterior surface of the ear.
How is auriculotemporal nerve stimulation used in migraine treatment?
Her phonophobia also became far less debilitating. The authors of the study concluded that auriculotemporal nerve stimulation may be useful tool in the treatment of refractory pain in the temporal distribution due to chronic migraine.
