Muscular Anatomy of the Face

There are quite a few anatomy resources on the web, but not a lot that combine clear illustrations with pictures of the muscles in action. With the help of a patient model and a fine illustrator, I hope this resource helps clarify how the face can make so many expressions.

You will also find a link to my Craniometric Landmarks web app which is a part of my online forensic sculpture class.

Depressor labii inferioris

This muscle, like the Depressor anguli oris, brings the lower lips down and outwards. It stretches the lowerlip. It's used in sad expressions. When acting in some individuals, it makes distinct cord-like inflections in the surface form that extend from the lateral portion of the lower lip to the lower extent of the muscle.
