Muscles of the Head

Muscles of the Head 
The muscles of the head are divided into the mus­cles of facial expression and the muscles of mastication.
Muscles of Facial Expression 
Frontalis lies over the frontal bone and raises the eyebrows and wrinkles the brow.
Orbicularis oculi is a ringlike band of muscle that encircles (forms an orbit about) the eye. It causes the eye to close or blink and is responsible for crow's feet at the eye corners.
Orbicularis oris encircles the mouth and is used to pucker the lips, as in forming a kiss.
Buccinator is located in the cheek area, and when it contracts, the cheek is compressed, such as when a person whistles or blows out air. (This muscle is also called the trumpeter's muscle.) Important to everyday life, this muscle helps hold food in contact with the teeth during chewing.
Zygomaticus extends from the zygomatic arch (chee.'­bone) to the corners of the mouth. It raises the corner: of the mouth when a person smiles.
Muscles of Mastication 
The muscles of mastication are used when we chew fooe Masseter extends from the zygomatic arch to the mandible. It is a muscle of mastication (chewing) because it raises the mandible.
Temporalis is a fan-shaped muscle that overlies the temporal bone. It acts as a synergist to the masseter.
The muscles of the head are divided into those for facial expression and those for mastication (chewing).
