How the Body Works : Release of Urine

Release of Urine

The release of urine from the bladder is controlled by the autonomic nervous system, which acts on the muscular wall of the bladder and an internal sphincter. Voluntary nerve impulses control the actions of an external sphincter, so that urine can be voided at convenient times. As the bladder fills, sympathetic nerve impulses, shown in red, increase, keeping the internal sphincter firmly closed. When the parasympathetic nerve output and the internal output, shown in blue, cause the bladder wall to contract, the internal sphincter is opened. As this occurs, controlled voluntary impulses may also cease and urine can then be released.

I'm increasingly understanding specifically the role of the sympathetic nervous system in this function! Many earlier mysteries are being cleared up, though I admit some new questions are raised, to which, after my own fashion, I shall seek answers. Thank you.

@MegaLol555 that can happen after sex and it's normal. If there's burning you could have a urinary tract infection and need antibiotics. If it doesn't empty or doesn't feel like it empties all the way you could have bph benign prostatic hypertrophy. Just thickening of the cells of the prostate. That needs to have a physician evaluate it. It can be treated successfully with medication. For now you can just milk the sucker like a snake, squeezing from the bottom up and that usually does it.
