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.
