The Anterior Auricular Muscle is a small muscle located in the human ear. It is one of the three auricular muscles that control the movements of the outer ear, the other two being the superior auricular muscle and the posterior auricular muscle.

Anatomy[edit | edit source]

The anterior auricular muscle, also known as the musculus auricularis anterior, originates from the lateral edge of the galea aponeurotica, and its fibers converge to be inserted into a projection on the front of the helix.

Function[edit | edit source]

The anterior auricular muscle helps in moving the ear forward. However, the functionality of this muscle varies among individuals. Some people can voluntarily control these muscles to move their ears, while others cannot.

Clinical Significance[edit | edit source]

Although the anterior auricular muscle is not associated with any major diseases or conditions, its presence can be used as a landmark during ear surgery.
