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.

Orbicularis oris

The Orbicularis oris is a circular muscle that surrounds the lips. The muscle can act in part or all together to create a vast number of expressions. Additionally, many muscles meet along its edges, which further varies its influence on expression. In the images, below, the muscle is contracted so that the lips are pushed forward into a pucker.
