ANATOMY

Detailed explanation-1: -The masseter is one of the muscles of mastication. It is a powerful superficial quadrangular muscle originating from the zygomatic arch and inserts along the angle and lateral surface of the mandibular ramus. The masseter is primarily responsible for the elevation of the mandible and some protraction of the mandible.

Detailed explanation-2: -masseter, (from Greek masasthai, “to chew”), prominent muscle of the jaw. The masseter arises from the zygomatic bone (cheekbone) and is inserted at the rear of the mandible (jawbone). Contraction of the muscle raises the mandible, and it is particularly used in chewing food.

Detailed explanation-3: -The primary muscles include: Masseter. Temporalis. Lateral pterygoid.

Detailed explanation-4: -Here’s temporalis, the largest of the muscles of mastication. It’s shaped like a fan. The temporalis arises from the wide area on the side of the skull that lies within the temporal line. The fibers of temporalis converge from above, and from behind, on the coronoid process.
