Abstract
1) A rapid increase in bladder pressure regularly caused an increase in contraction of the stomach and inhibition of the small intestine. Tne motor response was usually produced in the dog which has a strong peristaltic contraction of the stomach. The inhibitory response of the small intestine was reversed to a motor response by applying nicotine to the coeliac plexus.
2) The motor afferent nervous pathway is the pelvic nerves, and this can also be demonstrated by the central stimulation of the pelvic nerves. Tne inhibitory afferent nervous pathway is the hypogastric nerves which can also be demonstrated by the central stimulation of the hypogastric nerves.
3) The efferent nervous pathways of the motor and inhibitory response of this reflex are contained in both the splanchnic and vagus nerves.
