The Temporomandibular Joint Through the Lens of Comparative Anatomy

The temporomandibular joint (TMJ) is a feature that distinguishes mammals from other vertebrates and to a lesser or greater degree have similar anatomic features (J Musculoskelet Neuronal Interact, 3:391–394, 2003). Specifically, the head of the mandible and the squamous temporal bone are covered by a thin fibrocartilage layer and separated by a disc that bisects the joint into two noncommunicating compartments. However, despite these general anatomic similarities, the TMJ does exhibit profound functional differences across mammals, which are evolutionary adaptations to the species-specific demands placed on the joint.
