The muscle that is NOT a muscle of mastication is the Buccinator.

Here's why:

1. The muscles of mastication are primarily responsible for the movement of the jaw and are involved in the process of chewing.

2. The four main muscles of mastication are the Masseter, Temporalis, Medial Pterygoid, and Lateral Pterygoid.

3. The Masseter is the main muscle used for chewing because it elevates the mandible (lower jaw) to close the mouth, and it can also move the mandible from side to side.

4. The Temporalis elevates and retracts the mandible, moving the jaw backward and upward.

5. The Lateral Pterygoid moves the jaw forward, protruding the mandible, and moves the jaw from side to side.

6. The Buccinator, however, is not a muscle of mastication. It is a muscle of facial expression, and its primary function is to pull back the angle of the mouth and to flatten the cheek area, which aids in holding the cheek to the teeth during chewing, blowing, and whistling. It is not directly involved in the movement of the jaw for the process of chewing.
