TMJ syndrome - Essay Example The arterial blood supply of the temporomandibular joint is mainly from the superficial temporal and the maxillary arteries. The venous supply is by the corresponding arteries. The nerve supply of the joint is derived from the auriculotemporal nerve and the masseteric nerve. The movements of the normal joint include forward movement of the mandible, side to side movements which occur while eating food, lowering of the jaw for opening the oral cavity and then subsequently elevation of the joint for closing the mouth. There are around 35 million cases of this condition in the United States. The condition is known to have a greater predisposition towards women with the females being more affected than males with this condition. TMJ syndrome has been associated with many diseases which include inflammation of the joints of the body as well as hormonal problems and the pathology also has a hereditary component and hence genetic factors also tend to play a role. It is also associated with trauma which may result due to accidental injury or as a result of punch to the mandible. Accidental injury may be due to not wearing helmets or putting on the seat belt while driving. The symptoms associated with the injury include severe pain in the jaw which may also present with pain in the face and the neck. The movements of the joints become limited and it becomes increasingly difficult for the person to talk as well as move the jaw.
