The muscles in our neck and jaws are very active. If you think that the muscles allowing your jaws and mouth to move are engaged only when you eat, think again. These muscle groups are utilized in almost every movement of your skull, like when you talk, smile, laugh or even when wriggle your mouth in thought.
Connecting the lower and upper jaws to the skull is a joint known as the temporomandibular joint (TMJ). The TMJ has quite a complex network of its own, comprised of bones, ligaments, tendons, muscles, blood vessels, and nerves. This complex network can at times be stressed or suffer injury, leading to what is known as TMJ neck pain.
