Question

Describe the structure and control of muscles and sphincters involved in micturition.

Answer 1

Ans)

* The muscles involved in the Micturition, Detrusor and also the Urethral sphincters.

- The Micturition is also called as urination and the Micturition can be said as the action of removal of content present in the bladder.At the time when the bladder is filled with urine,the stretch receptors present in wall of bladder will stimulate the micturition reflex.

- Detrusor muscle which encircle the bladder will contract.The internal urethral sphincter will get relaxed, permitting the urine to move out of bladder to urethra.These two reactions are unintentional.But the external urethral sphincter is functioning voluntarily.It should be relaxed for the urine to move by means of urethra and external of the body.
