[Nervous regulation of contractile function of the rectum].

Basic systems of autonomic regulation of contractile function of the rectum are presented. Activation of the parasympathetic system has a predominantly stimulatory influence on the contractile function of the rectum. Activation of alpha1-, alpha2- and beta2-adrenergic receptors of the sympathetic nervous system inhibits contractile function of the rectum, and activation of alphal-adrenergic receptors stimulates contractile function of rectum sphinkters. The data about the effect of serotoninergic, purinergic, peptidergic, and nitrergic systems on the contractile function of the rectum are also presented.
