Current Question (ID: 14680)

Question:

During the process of micturition:

Options:

1. Urinary bladder Contracts, Urethral sphincter Contracts
2. Urinary bladder Contracts, Urethral sphincter Relaxes
3. Urinary bladder Relaxes, Urethral sphincter Contracts
4. Urinary bladder Relaxes, Urethral sphincter Relaxes

Solution:

The correct sequence during the process of micturition is: Urinary bladder Contracts Urethral sphincter Relaxes. When the urinary bladder is full, it sends a signal to the brain, which responds by initiating a reflex that causes the bladder to contract and the internal urethral sphincter to relax. This allows urine to flow from the bladder into the urethra. At the same time, the external urethral sphincter, which is under voluntary control, can also be relaxed to allow for further urine flow. When the bladder is emptied, the contraction stops and the sphincters return to their resting state to prevent urine leakage.
