The muscles work in combination to pivot the lower jaw up and down and to allow movement of the jaw from side to side.

Anatomy of jaw. The tooth sockets called alveoli open onto this surface. Its superior border is the alveolar process. Anatomy of the jaw in regards to jaw anatomy the major joint in the jaw is the temporomandibular joint tmj which connects the lower jaw to the skull temporal bone under the ear.

Tmj anatomy will help you understand in laymans terms what this joint is about and why it can cause so much migraine and facial pain. Hence temporo mandibular and then of course joint to get tmj. Anteriorly the two halves of the mandible fuse at the mandibular symphysis.

The mandible is the anatomical name of the jawbone. Some physicians associate disorder in this joint with tiny myofascial trigger points or contractions knots in the overworked or traumatized jaw muscles. Jaw either of a pair of bones that form the framework of the mouth of vertebrate animals usually containing teeth and including a movable lower jaw mandible and fixed upper jaw maxilla.

The mental protuberance at this junction forms the chin. These muscles are the masseter the temporalis the medial pterygoid and the lateral pterygoid. Jaws function by moving in opposition to each other and are used for biting chewing and the handling of food.

Each of these muscles occurs in pairs with one of each muscle appearing on either side of the skull. The mandible the largest and strongest bone of the face serves for the reception of the lower teeth.
