Much evidence indicates that there is an increased motor activity in the colon from eating in several species of animals. Though some of this effect may be cephalic in origin, the greater part of the response results from the arrival of food in the stomach and proximal intestine. Chemoreceptor stimulation appears to be more important than mechanoreceptor stimulation in bringing about this effect. The means by which this effect comes about could be either hormonal or neural. Several polypeptide hormones released from the proximal gut by eating are candidates. Neural pathways through both parasympathetic and sympathetic systems could be responsible. The exact nature of the change in colonic motility that is produced is unknown. It could involve changes in the pacemakers for colonic contractions (the electrical slow waves of the colon and the migrating spike burst of the colon), changes in the excitability of the colonic musculature or changes in colonic mucosal function.
许多证据表明，在几种动物中，进食会使结肠的运动活性增强。虽然这种效应的一部分可能源于头部因素，但大部分反应是由食物进入胃和近端肠道引起的。在产生这种效应方面，化学感受器刺激似乎比机械感受器刺激更重要。这种效应产生的方式可能是激素性的或神经性的。进食后从近端肠道释放的几种多肽激素是候选因素。通过副交感神经系统和交感神经系统的神经通路可能起作用。所产生的结肠动力变化的确切性质尚不清楚。它可能涉及结肠收缩起搏器（结肠的电慢波和结肠的移行峰暴）的变化、结肠肌肉组织兴奋性的变化或结肠黏膜功能的变化。
