TMJ muscles. Two powerful TMJ muscles can be seen on the side of the face. Notice two features in this second picture of our temporo mandibular joint anatomy tour. The actual joint, where the posterior prong fits into a socket in the temporal bone. The three muscles that slam the jaw closed.
The temporomandibular joint (TMJ), located just in front of the lower part of the ear, allows the lower jaw to move. The TMJ is a ball-and-socket joint, just like the hip or shoulder. When the mouth opens wide, the ball (called the condyle) comes out of the socket and moves forward, going back into place when the mouth closes. TMJ becomes dislocated when the condyle moves too far and gets stuck in front of a bony prominence called the articular eminence. The condyle can't move back into place.
