Question

Stimulation of voiding of urine occur in bladder at

• A. 200 ml
• B. 220 ml
• C. 300 ml
• D. 400 ml

Answer 1

The correct option is D 400 ml

As the bladder wall is stretched by the gradual filling of the bladder, stretch receptors in the wall of bladder generate nerve impulses that are carried by sensory neurons to the spinal cord and brain, producing the stimulation of voiding of urine. This sensation of fullness of bladder occurs at around 400 to 500 mL of urine.

So, the correct answer is option D.
