Structure
The superior auricular muscle originates from the epicranial aponeurosis.[1] Its fibres converge to be inserted by a thin, flattened tendon into the upper part of the medial surface of the auricle of the outer ear.[1]
It is the largest of the three auriculares muscles.[1] It is thin and fan-shaped.
Nerve supply
The superior auricular muscle is supplied by the temporal branch of the facial nerve (VII).[1][2]
