在正常生理情况下,胃肠平滑肌经常受到机械牵张(mechanical stretch),即张应变刺激,如食物进入胃、食糜进入小肠等情况下胃肠壁受牵张刺激。在某些常见疾病,如肠梗阻、胃肠痉挛、功能性消化不良引起的胃排空障碍等情况下,对胃肠道的牵张刺激更加明显。从运动的角度发动和参与胃 Under normal physiological conditions, the gastrointestinal smooth muscle is often subjected to mechanical stretch, which is stimulated by tensile strain, such as food entering the stomach and chyme entering the small intestine. In some common diseases, such as intestinal obstruction, gastrointestinal spasm, functional dyspepsia caused by gastric emptying disorders and other circumstances, the stretch of the gastrointestinal tract stimulation more pronounced.
