According to my book:
Sympathetic nervous system stimulation, leads to the release of Norepinephrine(Noradrenaline), priming the body for the "Fight or Flight" response.
It is also stated that:
The effect of sympathetic stimulation is to maintain urinary continence.
But if sympathetic stimulation results in urinary continence, why do we urinate more when afraid or nervous?
I've read this quesion, but the accepted answer states that adernaline(epinephrine) is released (not norepinephrine) and doesn't provide evidence to support why does adernaline result in more urination.
