The effect of disturbances in acetylcholine and sympathin synthesis on the regulation of ureteral motor activity

Abstract

The splanchnic nerves exert an inhibitory effect on the motor activity of the ureter on the side stimulated, due to the activity of sympathetic fibers, and also produce a stimulatory effect on the contralateral ureter, through involvement in the reaction of the posterior radicle fibers that enter into the composition of the nerve. The inhibitory effect is produced with the participation of sympathin, and the stimulatory one — with acetylcholine. Disturbances in the chemical synthesis of these mediators, under conditions of partial depancreatization or cauterization of the medullary layer of the adrenal glands, leads to marked disturbance in the neural regulation of ureteral motor activity.
