Is peeing a sympathetic response?
The sympathetic nervous system regulates the process of urine storage in the bladder. In contrast, the parasympathetic nervous system controls bladder contractions and the passage of urine.
Is increased urination sympathetic or parasympathetic?
In terms of urinary function, the parasympathetic nerves stimulate the detrusor to contract. Immediately preceding parasympathetic stimulation, the sympathetic influence on the internal urethral sphincter becomes suppressed so that the internal sphincter relaxes and opens.
Does sympathetic relax bladder?
When the bladder is full, afferent activity conveying this information centrally increases parasympathetic tone and decreases sympathetic activity, causing the internal sphincter muscle to relax and the bladder to contract.
Why do people pee when scared sympathetic?
When we’re under stress, our fight-or-flight response tends to kick in; this triggers a release of hormones, which disrupt the usual hormones which keep the bladder relaxed, causing it to contract. This results in people feeling the need to urinate, or even involuntarily urinating in some cases.
Why does sympathetic relax bladder?
When the sympathetic nervous system is active, it causes the bladder to increase its capacity without increasing detrusor resting pressure (accommodation) and stimulates the internal urinary sphincter to remain tightly closed.
Why do you pee when scared sympathetic?

How come when I get nervous I have to pee?
Can anxiety cause urge to pee?
The second theory is that anxiety and stress can cause muscle tension, which can affect the muscles of the bladder and increase the urge to urinate. Anxiety and depression are also associated with nocturia, which is the term for frequently waking during sleep to go to the bathroom.
