Temporomandibular joint – Temporomandibular disorder

The temporomandibular joint more commonly referred to as the TMJ is the small, delicate joint that connects your jaw to your skull. This joint is a complex system of muscles, ligaments, discs and bones that acts like a sliding hinge allowing the jaw to open, close, move to the side and forward. The jaw is one of the most complex and frequently used joints in the body. The jaw is used when we speak, breath, eat, drink, make facial expressions and even breathe.
