Masticatory Muscle

Masticatory muscle is a term encompassing the four primary muscles responsible for jaw movement and mastication, or chewing: the masseter, temporalis, medial pterygoid, and lateral pterygoid. These muscles are integral to oral function and form part of the stomatognathic system.

Each muscle carries out unique roles in mandibular motion. The masseter is potent in jaw closure while the temporalis aids in jaw retraction and elevation. The medial pterygoid aids in jaw closing and small contralateral movements whereas the lateral pterygoid assists with jaw opening and protrusion.

These muscles exhibit synchronised activity during mastication. Their balanced interaction ensures efficient bite force, bolus formation, and preparation for swallowing. Dysfunction in these muscles can lead to temporomandibular disorders or malocclusion.
