This book provides a comprehensive scientific investigation into every aspect of craniomandibular muscle function in both human and experimental animal studies. Topics discussed cover three broad areas: the anatomical, physiological, and histochemical aspects of these muscles; the special importance of these muscles to resting mandibular posture and mastication; and their role in clinically relevant problems involved with occlusion, craniomandibular disorders, and the growth and development of the cranioskeleton. Over 150 figures and tables are used to illustrate the concepts in these three areas. Methods for studying craniomandibular muscles are examined in depth, and the use of classically defined techniques such as electromyography and newer approaches using magnetic resonance spectroscopy and immunological identification of contractile proteins are discussed. Specialists in oral biology, orthodontics, oral surgery, prosthodontics, and craniomandibular disorders in schools and in private practice should consider this book an indispensable resource for their work and studies.
