The temporomandibular joint is the connection point between your jaw and your skull. The clues are in the name — tempor for the temporal bone and mandibular for the mandible. The connection point is in front of your ear, and you can feel it if you place your hand in front of your ear and open and close your jaw. The joint we’re talking about is the one that allows for that movement.
When there’s a disorder, that means there’s some issue with that joint that’s causing pain or other health problems.
