Structure

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]
