|
|

None of the above

Detailed explanation-1: -The brain signals the bladder muscles to tighten, which squeezes urine out of the bladder. At the same time, the brain signals the sphincter muscles to relax to let urine exit the bladder through the urethra. When all the signals occur in the correct order, normal urination occurs.
Detailed explanation-2: -When the bladder becomes full, the stretch receptors of the detrusor muscle send a signal to the pons, which in turn notifies the brain. People perceive this signal (bladder fullness) as a sudden desire to urinate, or urinary urge.
Detailed explanation-3: -Bladder emptying is known as urination. Urethra. A tube located at the bottom of the bladder that allows urine to exit the body during urination. All parts of the urinary tract-the kidneys, ureters, bladder, and urethra-must work together to urinate normally.
Detailed explanation-4: -If these nerves are damaged by illness or injury, the muscles may not be able to tighten or relax at the right time. In people with neurogenic bladder, the nerves and muscles don’t work together very well. As a result, the bladder may not fill or empty correctly.
