Muscle Supracranial Auricular Posterior

The supracranius auricularis posterior muscle (m. epicranius auricularis posterior) is a small paired muscle of the head located in the area of ​​the temporal bone behind the auricle.

It arises from the mastoid process of the temporal bone and attaches to the cartilage of the auricle. Innervated by the branches of the posterior auricular nerve (n. auricularis posterior).

The main function of the muscle is to pull the auricle back and upward. Participates in the movements of the auricle, changing the direction of the ear canal. In some mammals, it plays a more significant role in ear movement.

In humans, the supracranial auricular posterior muscle is poorly developed, but its contraction can draw attention to sounds coming from behind. It can also lift the pinna, making the ear canal more open.

Muscles and fascia of the head: supracranial posterior auricular muscle.

The supracranial posterior auricular muscle, or **m.****epicranius** **auricularis** **posterior**, is also called the **greater auricular abducens nerve**.

It covers the **mastoid process** of the temporal bone and passes to the back surface of the auricle and the skin of the forehead in the area of ​​the posterior border of hair growth. It is also located just above the artery called the occipital artery, which supplies the brain. The superior location of the muscle is the apex of the mastoid process
