The temporomandibular joints (TMJ) are located just in front of each ear and join the jaw to the face. TMJ movement can be felt by placing your fingers just in front of your ear while opening and closing your mouth. Ligaments hold the 2 sides of the joint in place while several muscles move the jaw. In the joint itself there is a small disc that helps guide the jaw movement.
