Question

What will happen if stretch receptors of urinary bladder wall are totally removed?

• A. There will be no micturition
• B. Urine will not collect in bladder
• C. Micturition will continue
• D. Urine will continue to collect normally in bladder

Answer 1

The correct option is (A):

Explanation of the correct option:

1. As the wall of the urinary bladder tends to stretch, the stretch receptor becomes active, which induces the response to urinate.
   
2. This feeling to urinate when the urinary bladder is completely stretched is called micturition.
   
3. Stretch receptors on the wall of urinary bladder sends impulse to CNS and in response, motor signals sent by CNS, initiates bladder contraction to release urine.
4. In the absence of stretch receptors, the micturition does not occur.
   

Explanation of the incorrect options:​

Option (B):

1. Urine will keep collecting in the bladder normally.
   
2. Absence of stretch receptors does not affect the movement of ​urine through the ureter into the urinary bladder.
   

Option (C):

1. ​Urine will keep collecting without any changes in the generation of urine from the kidney.
   

Final Answer: if stretch receptors of urinary bladder wall are totally removed then there will be no micturition.
