Muscle, Auricularis Nuchalis (M. Auricularis Nuchalis, Jna)

The auricularis nuchalis muscle (M. auricularis nuchalis) is a small muscle located in the ear and neck area. It is involved in maintaining the correct shape of the auricle and ensures its mobility.

The muscle starts from the external auditory canal and passes through the back surface of the auricle to the mastoid process. Its fibers connect with the fibers of other muscles, such as the sternocleidomastoid muscle and the trapezius muscle.

The functions of the auricularis muscle include:

– Maintaining the shape and shape of the auricle
– Ensuring mobility of the auricle during talking, chewing and other head movements
– Participation in maintaining the stability of the cervical vertebrae and joints.

When this muscle is damaged or diseased, various symptoms may occur, such as neck pain, difficulty turning the head, and decreased hearing.

To treat and prevent diseases of the ear nuchal muscle, it is recommended to exercise regularly, monitor your posture and eat right. You can also consult a doctor for diagnosis and appropriate treatment.
