The deep muscle layer of the cheek includes the masseter, buccinator, and levator anguli oris.
Your cheeks are composed of several layers, and within the deep muscle layer, specific muscles play key roles in facial movement, chewing, and expression. According to information dated 17-Mar-2016, the primary muscles found in the deep layer of the cheek are:
- Masseter: A large muscle located on the side of the face, responsible for chewing. It connects the jawbone to the cheekbone.
- Buccinator: A thin muscle forming the wall of the cheek. It helps with whistling, blowing, and keeping food between the teeth while chewing.
- Levator Anguli Oris: A muscle that lifts the angle of the mouth upward and laterally, contributing to smiling.
These muscles work together to facilitate various functions, from the essential task of mastication (chewing) enabled by the masseter and buccinator, to shaping facial expressions through the buccinator and levator anguli oris. Understanding these muscles provides insight into the complex mechanics of the face.
