Question

What will happen if stretch receptors are removed from urinary bladder?

Answer 1

Answer:

Stretch receptors (also called micturition receptors) are present in the wall of the urinary bladder.

Increase in volume of urine in the organ stretches (mechanical force) the receptors leading to Action potential along afferent nerves to the CNS.

The efferent nerves supply the detrusor muscle of the urinary bladder. Stimulation of the muscles contracts the bladder and helps in passing out urine.

Now, the first urge for urination comes when the volume of urine accumulated is 150 ml.

When the volume of urine accumulated is around 250 - 300 ml , extreme urge to urinate occurs.

Now, if the stretch receptors are removed, the person will not experience any urge to urinate. Neither will he/she feel any pain .

As a result after accumulation of around 500 ml of urine, the urinary bladder will burst leading to extravasation of urine into the pelvic cavity.

Answer 2
