Because loading during chewing is not totally predictable and jaw-closing muscles are strong and act over short distances, feedback from oral receptors is important in the control of mastication. Information on such feedback can be obtained by studying reflexes in jaw muscle EMGs. This review will deal with the contribution of reflex mechanisms to modifying motor neuron activity during chewing, and the dependency of reflex sensitivity on motor task, phase of movement, and site of stimulation.
由于咀嚼过程中的负荷并非完全可预测,且闭口肌力量强大且作用距离短,口腔感受器的反馈对于咀嚼控制至关重要。通过研究颌肌肌电图中的反射,可以获得有关此类反馈的信息。本综述将探讨反射机制在咀嚼过程中对调节运动神经元活动的作用,以及反射敏感性对运动任务、运动阶段和刺激部位的依赖性。
