What happens to the nerve ending when bladder walls stretch?

The bladder wall contains stretch receptors that are activated when the bladder is filled with urine. These receptors send signals to the spinal cord and brain, which in turn causes the urge to urinate. As the bladder wall stretches, the receptors become more active and the urge to urinate becomes more intense. If the bladder is not emptied, the receptors can become overloaded and the urge to urinate can become painful.

When the bladder is full, the nerve endings in the bladder become stretched and send signals to the central nervous system. This leads to the sensation of having to urinate. If the bladder is not emptied, the nerve endings can be stretched for a long period of time, which can cause them to become damaged. This can lead to incontinence, which is the loss of bladder control.
