Auriculotemporal nerve
Auriculotemporal Nerve
The Auriculotemporal Nerve (pronunciation: aw-ri-kyoo-loh-tem-puh-ruhl nərv) is a branch of the Mandibular Nerve, which is itself a division of the Trigeminal Nerve.
Etymology
The term "Auriculotemporal" is derived from the Latin words 'auricula', meaning 'ear', and 'temporalis', meaning 'of the temple'. Thus, the term refers to the nerve that supplies the region of the ear and temple.
Function
The Auriculotemporal Nerve provides sensory innervation to various regions of the head. It carries sensory information from the skin of the temple, the anterior part of the ear, the upper part of the external auditory meatus, and the external surface of the tympanic membrane. It also carries parasympathetic fibers to the Parotid Gland, thus playing a role in salivation.
