	Anatomical terms of muscle

The anterior auricular muscle, the smallest of the three auricular muscles, is thin and fan-shaped, and its fibers are pale and indistinct. It arises from the lateral edge of the epicranial aponeurosis, and its fibers converge to be inserted into a projection on the front of the helix.

Structure

The anterior auricular muscle arises from the lateral edge of the epicranial aponeurosis.^[1] It inserts into a projection on the front of the helix.^[1]

Nerve supply

The anterior auricular muscle is supplied is supplied by the temporal branch of the facial nerve (VII).^[2]^[3] It may also receive some small branches from the auriculotemporal nerve, a branch of the mandibular nerve, itself a branch of the trigeminal nerve (V).^[4]

Relations

The anterior auricular muscle is the smallest of the three auricular muscles.^[1]

The superficial temporal artery, a branch of the external carotid artery, travels underneath the anterior auricular muscle to supply the auricle of the outer ear.^[1]

Function

The anterior auricular muscle draws the auricle of the outer ear upwards and forwards.^[1] This is a very subtle movement in most people, although some people can wiggle their ears.^[1]
