Auricular nerve

Auricular Nerve

The nerves of the scalp, face, and side of neck. (Auricular nerve labeled at center right.)

The Auricular Nerve is a branch of the Vagus Nerve that provides sensory innervation to the skin of the ear and the external auditory meatus. It is also known as Arnold's Nerve.

Anatomy

The Auricular Nerve arises from the Jugular Foramen, a large aperture in the base of the skull. It is a mixed nerve, containing both sensory and motor fibers. The nerve travels posteriorly, passing between the internal and external jugular veins to reach the ear.

Function

The Auricular Nerve carries sensory information from the skin of the ear and the external auditory meatus to the brain. This includes sensations of touch, temperature, and pain. The nerve also carries parasympathetic fibers to the skin of the ear, controlling sweat and sebaceous gland function.

Clinical Significance

Damage to the Auricular Nerve can result in loss of sensation in the ear and surrounding areas. This can occur due to trauma, surgery, or conditions such as Bell's Palsy.
