This muscle works in conjunction with other facial muscles to control the movements of the lower lip.

Function of the Depressor Labii Inferioris

As the name suggests, the depressor labii inferioris has the primary function of depressing or lowering the lower lip.

This muscle plays a crucial role in facial expressions, especially those associated with sadness or displeasure.
