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: -The jaw elevator muscles develop the main forces used in mastication. The force generated during routine mastication of food such as carrots or meat is about 70 to 150 newtons (16 to 34 lbf). The maximum masticatory force in some people may reach up to 500 to 700 newtons (110 to 160 lbf).

Detailed explanation-3: -The muscles of mastication can be divided into the primary muscles and secondary or accessory muscles. The primary muscles include: Masseter. Temporalis.

Detailed explanation-4: -The strongest muscle based on its weight is the masseter. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars.

Detailed explanation-5: -If you follow the masseter around the underside of your jaw, it makes a sling with the medial pterygoid muscle. This muscle also helps close the jaw, along with moving it from side to side.
