We’ll move on now, to look at those four muscles. They’re known collectively as the muscles of mastication. The muscles that close the jaw are much more powerful than the ones that open it. Closing is produced by three large muscles on each side, the medial pterygoid, the temporalis, and the masseter. The primary muscles of mastication (chewing food) are the temporalis, medial pterygoid, lateral pterygoid, and masseter muscles.

Look it up now! Background: Mastication function is related to mandible movement, muscle strength, and bite force. No standard device for measuring bite force has been developed. A linear relationship between electromyographic activity and bite force has been reported by several investigators, but data on the reliability of this relationship remain limited in Asian young adults.

Synonym(s): musculus masticatorii [TA], muscles of Mandible and Muscles of Mastication Axial 1 Normal Anatomy Four paired muscles—temporalis, masseter, medial pterygoid, and lateral pterygoid—are the primary muscles of mastication, responsible for adduction and lateral motion. In the axial MR image on the next page, note the temporalis muscle superficial to the temporal lobe of the brain. The muscles of mastication aid jaw movements and are one of the main muscle groups present within the head, (the other being the muscles of facial expression). There are four muscles of mastication – the masseter, temporalis, medial pterygoid and lateral pterygoid. Each muscle has its own origin, insertion and specific function About this Quiz.

MUSCLES OFMASTICATION 2.  The process by which food is crushed and ground by teeth The first step of digestion Increases the surface area of food to allow more efficient breakdown by enzymes Food after swallowing is called BOLUS 3. The muscles are: The masseter (composed of the superficial and deep head) The temporalis (the sphenomandibularis is considered a part of the temporalis by some sources, and a distinct muscle by The medial pterygoid The lateral pterygoid The muscles of masticationcan be divided into primary and secondary groups according to whether they connect the mandible directly to the skull or if they attach to other structures in the neck, e.g. hyoid, thyroid cartilage.

Chewing food increases its surface area and allows for better digestion. Chewing requires teeth, the maxilla and mandible bones, the lips, the cheeks, and the masseter, temporalis, medial pterygoid, and lateral pterygoid muscles. The main muscles of mastication in many cases are referred to as muscles of mastication. Clinical Significance The muscles of mastication and their motor innervation can be analyzed medically by requesting the patient to clench his teeth repeatedly and after that palpating the temporalis and masseter in the temporal fossa and over the ramus of mandible, respectively.
