Oblique Muscle of Auricle

The muscles of the auricle. (Oblique muscle visible at center right.)

The Oblique Muscle of Auricle is a small muscle located in the human ear. It is one of the intrinsic muscles of the outer ear, which are responsible for the minor movements of the ear.

Anatomy

The Oblique Muscle of Auricle originates from the eminentia conchae, a part of the auricle of the ear, and inserts into the upper part of the cranial surface of the concha. It is a thin, flat, and pale muscle, which is often indistinct and blends with the surrounding tissues.

Function

The primary function of the Oblique Muscle of Auricle is to adjust the shape of the ear for better sound localization. It helps in the movement of the ear towards the sound source, thus enhancing the ability to determine the direction of the sound.

Clinical Significance

Although the Oblique Muscle of Auricle is not typically associated with any specific medical conditions, any damage or injury to this muscle can potentially affect the movement of the ear and sound localization.
