哺乳动物的咀嚼是由内在的节律性神经模式和由效应系统（肌肉、骨骼、关节、牙齿、软组织）与食物的相互作用产生的感觉反馈的相互作用引起的。解释人类咀嚼模式变化的主要变量是受试者本身，他们的年龄，吃的食物类型，以及一系列运动的时间。咀嚼的内在模式是由位于脑桥和延髓的中央模式发生器（CPG）产生的。CPG的输出被来自大脑高级中心的输入和来自感觉受体的反馈所修改。口内触觉感受器、下颌闭合肌中的肌梭和牙周膜中的专门机械感受器对运动参数具有特别强大的影响。
Mammalian mastication results from the interaction of an intrinsic rhythmical neural pattern and sensory feedback generated by the interaction of the effecter system (muscles, bones, joints, teeth, soft tissues) with food. The main variables that explain variation in the pattern of human mastication are the subjects themselves, their age, the type of food being eaten, and time during a sequence of movements. The intrinsic pattern of mastication is generated by a central pattern generator (CPG) located in the pons and medulla. The output of the CPG is modified by inputs that descend from higher centers of the brain and by feedback from sensory receptors. Intraoral touch receptors, muscle spindles in the jaw-closing muscles, and specialized mechanoreceptors in the periodontal ligament have especially powerful effects on movement parameters.
