The facial muscles (facial muscles) is a group of 26 muscles in humans, which is not only necessary for opening and closing the eyes or mouth, but also moves the skin of the face and thereby controls facial expressions. The muscles of the face are divided into the ear muscles, the nasal muscles, the mouth muscles, the muscles of the eyelid and the muscles in the area of the skull.
Unlike other muscles in the body, the mimic muscles must do not move joints.
For this reason, they don't start bone on, but lie just under the skin.
They usually will named after their function and location and will all through the facial nerve (7. cranial nerve) innervated.
Due to the axial symmetry of the face, almost all facial muscles are duplicated.

It is divided into three parts:
The eyelid gap muscles also include the Corrugator supercilii muscle. This pulls the Eyebrows down and to the middle and throws up a longitudinal crease in the middle of the forehead.
On the ear are three muscles, of the Auricularis anterior muscle, posterior and superior.
This move the auricle forwards / backwards / upwards.
However, not all people can actively contract these muscles and thereby “wiggle their ears”.
Also lie in the area of the skull roof facial muscles.
You often will summarized as the epicranius muscle and are loosely connected to the periosteum but firmly attached to the roof of the skull.
Of the Occipitofrontalis muscle lifts with his front part (Venter anterior) the eyebrows and frowns, with his rear portion (Venter posterior) he smooths his forehead.
The Galea aponeurotica is through the Temporoparietalis muscle stretched in the transverse direction. This taut tendon plate covers the roof of the skull and serves as a starting point for some mimics muscle fibers.
