The muscles are: 1  The masseter (composed of the superficial and deep head). 2  The temporalis (the sphenomandibularis is considered a part of the temporalis by some sources, and a distinct muscle by others). 3  The medial pterygoid.4  The lateral pterygoid.here are four classical muscles of mastication. During mastication, three muscles of mastication (musculi masticatorii) are responsible for adduction of the jaw, and one (the lateral pterygoid) helps to abduct it.
It covers the majority of the temporal bone and lesser portions of the frontal and parietal bones. The upper margin of the muscle follows the superior temporal line. Insertion: The temporal muscle inserts on the coronoid process of the mandible.Action: The temporal muscle acts in unison with the masseter and internal pterygoid muscles to close the jaws. Very importantly, it also helps to retrude or pull back the mandible.he depressors of the mandible act to open the lower jaw widely, a function which the muscles of mastication cannot perform. MUSCLES OF MASTICATION There are four paired muscles of mastication. They are the masseters, the temporals, the internal pterygoids, and the external pterygoids.
