当牙受到压力时由于刺激牙周膜的压力感受器可引起生物电的释放。由此可知开(牙合)运动神经原的激活而产生开(牙合)反射,同时产生闭(牙合)运功神经原的抑制。有人指出,由于牙周膜感受器的正反馈作用可增大随意闭(牙合)
When the tooth is under pressure, the release of bioelectricity can be caused by the baroreceptor that stimulates the periodontal ligament. This shows that open (occlusal) motor neuron activation and produce open (occlusal) reflex, at the same time produce closed occlusal motor neurons inhibition. It was pointed out that due to the positive feedback of periodontal membrane receptors can increase the random closure (occlusion)
