The motility of the mammalian gastro-intestinal tract is regulated by a number of neuronal systems. The postganglionic, intramural parts of these systems are characterized by their neurotransmitters as cholinergic, adrenergic and 'purinergic' nerves, respectively. The transmitter acetylcholine evokes contractions of the smooth muscle cell, whereas both noradrenalin and the transmitter from the 'purinergic' nerves, presumably ATP, induce relaxations of smooth muscles. Agents and actions which influence the neurohumoral transmission and the mechanisms underlying the effects induced by the transmitters in smooth muscle cells are reviewed.
哺乳动物胃肠道的运动受多种神经调节系统的控制。这些系统神经节后的壁内部分，其特征在于其神经递质分别为胆碱能神经、肾上腺素能神经和“嘌呤能”神经。神经递质乙酰胆碱可引起平滑肌细胞收缩，而去甲肾上腺素和“嘌呤能”神经的递质（可能是三磷酸腺苷）均可诱导平滑肌舒张。本文综述了影响神经体液传递以及递质在平滑肌细胞中产生效应的潜在机制的药物及作用。
