Q. What will happen if the stretch receptors of the urinary bladder wall are totally removed?
A) Micturition will continue
B) Urine will continue to collect normally in the bladder
C) There will be no micturition
D) Urine will not collect in the bladder
Explanation
[Solution from source] Micturition is a reflex: stretch receptors in the filling bladder send signals to the CNS, which then sends motor messages to contract the bladder muscle and relax the sphincter. Without stretch receptors, the reflex cannot start, so there will be no micturition. Urine would still reach the bladder from the ureters, but voluntary/reflex emptying would fail. Answer (3).
