Stretch reflex of bladder is integrated at
Correct Answer: Sacral poion
Description: The bladder smooth muscle has some inherent contractile activity; however, when its nerve supply is intact, stretch receptors in the bladder wall initiate a reflex contraction that has a lower threshold than the inherent contractile response of the muscle. Fibers in the pelvic nerves are the afferent limb of the voiding reflex, and the parasympathetic fibers to the bladder that constitute the efferent limb also travel in these nerves. The reflex is integrated in the sacral poion of the spinal cord.Ref: Ganong&;s review of medical physiology,23rd edition, page: 662
