胃肠道的推动力由局部的、非推动性混合运动 (摆动或节段性运动 )与推动性(蠕动 )运动组成。一般认为 ,混合运动由固有的产生节律性收缩的节律生成器诱发 ,而蠕动则通过固有的兴奋与抑制神经反射途径 ,但对混合与蠕动的关系甚少了解。在小鼠 ,缺乏 Cajal间质细胞使蠕动减弱 ,提 The driving force of the gastrointestinal tract by the local, non-promoting mixed movement (swing or segmental movement) and pushing (peristaltic) movement. It is generally assumed that mixed motions are induced by the rhythmic generator that produces rhythmic contractions and that peristalsis is intrinsically excited and inhibits the reflex pathway, but little is known about the relationship between mixing and peristalsis. In mice, lack of Cajal interstitial cells weakens the motility
