ANATOMY

Detailed explanation-1: -The masseter muscle provides powerful elevation and protrusion of the mandible by originating from the zygomatic arch and inserting along the angle and lateral surface of the mandible. The temporalis muscle originates from the floor of the temporal fossa and inserts onto the coronoid process of the mandible.

Detailed explanation-2: -Attachments of Temporalis Muscle: Origin & Insertion Origin: (proximal attachments): Temporal lines, temporal fossa, and temporal fascia. Insertion: (distal attachments): Tip and medial surface of coronoid process of mandible.

Detailed explanation-3: -The masseter muscle fibers converge inferiorly, forming a tendon that inserts the outer surface of the mandibular ramus and coronoid process of the mandible.

Detailed explanation-4: -In addition, the temporalis muscle contributes to grinding movements by moving the mandible from side to side.

Detailed explanation-5: -Masseter muscle is a paired, strong, thick and rectangular muscle that is originating from the zygomatic arch and extends down to the mandibular angle. It consists of a superficial and a deep part.
