Craniomandibular Disorders: Diseases or disorders of the muscles of the head and neck, with special reference to the masticatory muscles. The most notable examples are TEMPOROMANDIBULAR JOINT DISORDERS and TEMPOROMANDIBULAR JOINT DYSFUNCTION SYNDROME.Dental Occlusion, Traumatic: An occlusion resulting in overstrain and injury to teeth, periodontal tissue, or other oral structures.Felidae: The cat family in the order CARNIVORA comprised of muscular, deep-chested terrestrial carnivores with a highly predatory lifestyle.Masticatory Muscles: Muscles arising in the zygomatic arch that close the jaw. Their nerve supply is masseteric from the mandibular division of the trigeminal nerve. (From Stedman, 25th ed)Bite Force: The force applied by the masticatory muscles in dental occlusion.Temporomandibular Joint Disorders: A variety of conditions affecting the anatomic and functional characteristics of the temporomandibular joint. Factors contributing to the complexity of temporomandibular diseases are its relation to dentition and mastication and the symptomatic effects in other areas which account for referred pain to the joint and the difficulties in applying traditional diagnostic procedures to temporomandibular joint pathology where tissue is rarely obtained and x-rays are often inadequate or nonspecific. Common diseases are developmental abnormalities, trauma, subluxation, luxation, arthritis, and neoplasia. (From Thoma's Oral Pathology, 6th ed, pp577-600)Mandible: The largest and strongest bone of the FACE constituting the lower jaw. It supports the lower teeth.Skull: The SKELETON of the HEAD including the FACIAL BONES and the bones enclosing the BRAIN.
