Temporomandibular joint (TMJ) syndrome or TMJ joint disorders are medical problems related to the jaw joint. The TMJ connects the lower jaw (mandible) to the skull (temporal bone) in front of the ear. Certain facial muscles control chewing. Problems in this area can cause head and neck pain, a jaw that is locked in position or difficult to open, problems biting, and popping sounds when you bite.
The TMJ is comprised of muscles, blood vessels, nerves, and bones. You have two TMJs, one on each side of your jaw.
Muscles involved in chewing (mastication) also open and close the mouth. The jawbone itself, controlled by the TMJ, has two movements: rotation or hinge action, which is opening and closing of the mouth, and gliding action, a movement that allows the mouth to open wider. The coordination of this action also allows you to talk, chew, and yawn.
