Corpus: Mentalis muscle: Unterschied zwischen den Versionen

Aktuelle Version vom 15. Oktober 2024, 10:00 Uhr

from Latin: mentum - chin
Synonym: chin muscle

Definition

The mentalis muscle is a superficial muscle located in the chin area, responsible for tightening the skin of the chin. It is part of the facial expression (mimic) musculature.

Course

The mentalis muscle originates from the mandible in the incisive fossa, specifically on the alveolar wall of the second mandibular incisor. The muscle fibers extend downward and insert into the skin of the chin.

Innervation

The mentalis muscle is innervated by the marginal mandibular branch of the facial nerve (cranial nerve VII).

Function

The mentalis muscle elevates the skin of the chin and, in conjunction with other facial muscles, pushes the lower lip forward. This action contributes to expressions such as pouting or "being offended." The muscle is fused with the underlying skin, which causes the skin to follow its movements.

 ==Function==
-The mentalis muscle pulls the chin skin upwards and pushes the lower lip forwards in co-operation with other facial muscles. It thereby produces the expression of pouting or "being offended". It is fused with the corium, which causes the skin to follow the muscle movements.
