The temporomandibular (TM) joints join the skull and lower jawbone (mandible). These gliding "ball and socket" joints are located just in front of each ear, and they move when a person opens and closes his or her mouth.

The TM joints are stabilized by muscles that attach directly to the jawbone. They are separated by a disc made of cartilage, which keeps the two bones from rubbing together.
