Tonight, I want to know about the relationship of the amount of urine volume with nerve responses in adults. That’s an example. R n r nHelp please the info :))

Good evening, thanks for the question


Urinary reflexes in humans are regulated by the central nervous system (spinal cord and cortex of the brain) and the peripheral nervous system (parasympathetic nervous system). Even though it is governed by the autonomic nervous system, this reflex can be consciously restrained.


When the volume of urine in the bladder reaches 200 ml, there will be an increase in pressure in the bladder which will trigger receptors in the bladder muscle wall, where the muscle is very sensitive to the strain in the bladder because of the urine volume, to then send signals to the medulla spinalists that trigger the urge to urinate.


Furthermore, nerve signals will trigger the bladder wall muscles to contract and relax the internal sphincter which is important in the process of urination.


Then the signal will be sent to the cortex of the brain which produces a sensation of full taste so that someone will consciously want to urinate. At that time the external sphincter muscle will contract to hold the urination process.


However, the maximum volume that can be held is around 500 ml where at that time the pressure is high enough to cause relaxation of the external sphincter muscle so that the urination process occurs.


So, hopefully it can be useful
