Which muscle is also known as Triangularis?

Explanation:
Triangularis describes a muscle that forms the triangular area at the corner of the mouth and pulls that corner downward, producing a frowning expression. This muscle is the Depressor Anguli Oris, located along the lower jaw from the mandible to the angle of the mouth, and its action is to depress the corners of the mouth. The other muscles have different roles: lifting the corners of the mouth, lifting the upper lip, or moving the nostrils, so they don’t share this triangular/ downward-depressing function.
