Cambridge dictionary describes Jaw as the lower part of the face that moves when the mouth is open and shut. The lower jaw is called mandible and fixed upper jaw is called maxilla. The joint where the mandible meets the skull is the temporomandibular joint. Jaws function by moving in opposition to each other and are used for biting, chewing, and the handling of food.
Wikipedia : Jaw is a structure at the entrance of the mouth, typically used for grasping
and manipulating food. Jaws function by moving in opposition to each other and are used for biting, chewing, and the handling of food. The upper jaw is firmly attached to the nasal bones at the bridge of the nose. The arched lower part of the maxilla contains the upper teeth. Inside the body of the bone is the large maxillary sinus. In the human fetus and infant both the upper and lower jaws have two halves; these fuse at the midline a few months after birth. The mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human face. It forms the lower jaw and holds the lower teeth in place. Jaw popping can be a painful sensation that's caused by dysfunction of the temporomandibular joints (TMJ). These joints connect the jawbone to the skull, with one joint on each side. ... When the joint doesn't work properly, popping can occur. The term TMJ is used both to refer to the joint and to the disorder.
Jaw problems include Fractures, Dislocations, Temporomandibular joint dysfuntion,
Osteonecrosis and cancers. Treatment of jaw problems depends on the cause.
Care of the Jaw Becoming more aware of tension-related habits — clenching your jaw, grinding your teeth or chewing pencils — will help you reduce their frequency. The following tips may help you reduce symptoms of TMJ disorders Avoid over-use of Jaw muscles : Eat soft foods. Cut food into small pieces. Steer clear of sticky or chewy food. Avoid chewing gum. Stretching and massaging : The doctor, dentist or physical therapist may show how to do exercises that stretch and strengthen the jaw muscles and how to massage the muscles. Heat or cold : Applying warm, moist heat or ice to the side of your face may help alleviate pain.
Athletes can suffer jaw injuries during sports even with all the right equipment and
skill. A study showed that nearly half of elite field hockey players will suffer mouth,
tooth, or jaw injuries. Any time one plays a sport, be mindful of mouth and jaw and do
what one can to prevent injuries. Volleyball, soccer, basketball, football, martial arts,
and many other activities can put jaw at risk.
