Temporomandibular Joint Disorder (TMJ)

Temporomandibular Joint Disorder (TMJ)

by Stephanie Meadows
The temporomandibular joint (TMJ) is one of the most heavily utilized joints in the human body. Mechanically, the TMJ is what allows you to open and close your mouth, and to a lesser extent, extend and move your jaw from side to side. Functionally, it facilitates eating, talking, and facial expressions. Like so many parts of the human body, the TMJ usually only receives attention when something goes wrong.
