Anatomy of the masticatory system

Abstract

In order to appreciate the normal function and dysfunction of any system, and more specifically the stomatognathic system, the starting point should involve a complete and thorough understanding of the anatomy of this system. The masticatory system is composed of an array of rather complex anatomical structures that often operate in unison to provide unique and selective daily functions. The orchestration and coordination of the muscles, bones, nerves, and vessels allow human beings to perform functions only capable by our species. However, when this finely tuned arrangement is upset, the outcome, in some individuals, may involve pathosis involving dysfunction, dysregulation, and/or pain. This chapter provides a descriptive anatomical review of the masticatory system. Ultimately, this knowledge will assist the clinician in recognizing specific disorders, their signs and symptoms, diagnosis and treatments, and the relationship to the anatomic structures of this intricate system.
