Review reveals conserved jaw muscle motor patterns despite anatomical diversity across mammals, indicating sensory feedback and evolutionary adaptations optimize chewing mechanics.

Key Points

Synthesize findings on the evolutionary development, ontogeny, motor control mechanisms, and biomechanical modeling of mammalian feeding and mastication.
Review of comparative physiological, electromyographic, and anatomical studies examining jaw-closing patterns and feeding transport cycles across mammalian species.
Evaluation of biomechanical assessments of occlusal forces, suckling-to-chewing developmental transitions, and three-dimensional computer modeling applications.
Electromyography demonstrates a striking uniformity of jaw-closer motor patterns across mammalian taxa despite substantial evolutionary diversification in jaw anatomy.
Unilateral occlusal movements replaced the slow closing phase of primitive symmetrical cycles to enhance mammalian chewing efficiency.
Sensory feedback plays a dominant role in shaping masticatory cycles, while suckling motor patterns closely mirror mastication, pointing to a gradual postnatal transition.
