hey! i know being all nervous is part of the autonomic nervous system, more specifically the sympathetic division, but why, physiological, do we pee when we are really nervous?

The sympathetic nervous system is activated by the "three-F" stimulus, that is flight, flee, or, um, a four-letter F word that will be censored by the server. Since the muscles that control the flow of urine from the bladder are not essential muscles in conflict situations, they relax to allow emergency functions to maintain after injury, such as would happen in a fight. When the bladder sphincters relax, we pee; hence, we pee when the sympathetic nervous system is overstimulated.

Control of bladder contraction is done by Detrusor muscular sphincter . This sphincter keeps the bladder closed . This sphinctric control is under the influence of Parasympathetic nervous system. During a sudden fright or flight respose as in intense fear Sypmathetic nervous activity predominates over Parasympathetic.So the parasympathetic activity suddenly gives in . Sympathetic nerves contract the bladder muscle while the sphincer loses control. So urine is voided.
