According to the location (topography) of the facial muscles (mimic) are divided into the muscles of the cranial vault; muscles surrounding the ocular gap; muscles surrounding the nasal aperture (nostrils); muscles surrounding the mouth opening and the muscles of the auricle.

Muscles of the cranial vault

The skull of the skull is covered by a single muscular-anoneurotic formation - the supracerebral muscle (m.epicranius), in which the following parts are distinguished:

  • an occipitus-frontal muscle;
  • a tendon helmet (supracranial aponeurosis);
  • temporomandibular muscle.

 Muscles of the cranial vault

Muscles surrounding the fissure

The eye slit is surrounded by bundles of the circular eye muscle, in which several parts are prominent.

 Muscles surrounding the fissure

Muscles surrounding the nasal aperture

In the area of the nasal apertures there are several small, weakly developed muscles that widen or narrow these openings. This is the nasal muscle and the muscle that lowers the septum of the nose.

Muscles surrounding the orifice of the mouth

There are several well-defined muscles around the mouth opening. These muscles include the circular muscle of the mouth, the muscle that lowers the corner of the mouth, the muscle that lowers the lower lip, the chin and the buccal muscles, the muscle that lifts the upper lip, the small and large zygomatic muscles, the muscle that raises the corner of the mouth, and the muscle of laughter.

Muscles of the auricle

Muscles of the auricle are weak in man. Very rarely is the ability to move the auricle, which is combined with the simultaneous contraction of the occipitus-frontal muscle. There are anterior, upper and posterior ear muscles.
