The principal muscle of mastication that closes the mouth is the masseter muscle. This powerful muscle is located at the back of the jaw and plays a key role in elevating the mandible to facilitate chewing. It works in conjunction with other muscles, such as the temporalis and pterygoid muscles, to enable effective movement of the jaw during mastication.
