The large intestine has distinct motility patterns which include non-rhythmic haustral kneading of ingesta and stronger rhythmic retropulsive and propulsive contractions which move ingesta along the tract. A variable site electrical pacemaker exists at the pelvic flexure where the strong rhythmic contractions begin. The large intestine can contract adequately with only the intrinsic nerve supply intact. Neurotransmitters have profound effects on large intestinal activity.
大肠具有独特的运动模式，包括对食糜进行无节律的袋状揉动，以及更强的有节律的逆蠕动和推进性收缩，这些收缩使食糜沿肠道移动。在盆腔弯曲处存在一个可变位置的电起搏器，强烈的有节律收缩由此开始。仅在内在神经供应完整的情况下，大肠就能充分收缩。神经递质对大肠活动有深远影响。
