胃肠内容物靠蠕动运动自口腔侧运往肛门侧。蠕动运动的基础是胃肠平滑肌的自律性。壁内神经丛对调节蠕动运动具有重要意义。这些神经元的活动受脊髓、脑干等部位的调节,而后者又受丘脑下部和边缘系统等较高部位的控制。此外,由消化道粘膜和胰腺的内分泌细胞所分泌的激素(胃泌素、胆囊收缩素、5-HT,胃动素、胰岛素、胰高血糖素)及在胃肠壁内含有各种肽类物质(血管活性肠肽、P物质、脑啡肽)的肽能神经元和5-HT能神经元与胃肠运动的细 Gastrointestinal contents by peristalsis movement from the oral side to the anus side. The basis of motility is the self-discipline of the gastrointestinal smooth muscle. Wall plexus on the regulation of peristaltic movement of great significance. The activity of these neurons is regulated by the spinal cord, brain stem and other parts, which in turn are controlled by the higher parts of the hypothalamus and limbic system. In addition, hormones (gastrin, cholecystokinin, 5-HT, motilin, insulin, glucagon) secreted by the endocrine cells of the gut mucosa and pancreas and various peptides contained in the gastrointestinal wall Substance (vasoactive intestinal peptide, substance P, enkephalin) peptide neurons and 5-HT neurons and gastrointestinal motility fine
