What is the scientific name of the muscle that facilitates the raising of the lower lip? Is it on the ventral or dorsal side of the body?

Mentalis is the scientific name of the muscle that is responsible for raising of lower lip and it is present on the ventral side of the body.

Explanation:

Mentalis, also known as the pouting muscle, is a muscle of the lower lip which is present on the tip of the chin.

The contraction of the mentalis muscle causes the chin to move in a upward-inward motion, which wrinkles the skin of the chin and also results in the elevation of the chin and the lower lip.

Mentalis muscle which is present on the tip of the chin is on the ventral or front side of the body.
