Inhibitory interactions between colonic and vesical afferents in the micturition reflex of the cat.

摘要: 1. In anaesthetized cats in which the only intact autonomic pathways innervating colon and bladder were pelvis nerves, distension of resulted a graded inhibition spontaneous motility, decrease reflexly evoked waves activity vesical branches pelvic nerves. 2. Electrical stimulation with voltages sufficient to excite myelinated fibres colonic nerve caused an increase micturition threshold, reduction efferents nerve. 3. The results demonstrate that afferent inflow from produces marked central inhibitory influence on reflex.
