Dominant innervation for the bladder is through which type of activity?

Explanation:
Bladder emptying is driven mainly by parasympathetic activity that releases acetylcholine to stimulate the detrusor muscle. This cholinergic signal acts on muscarinic receptors, especially M3, causing the detrusor to contract and initiate urination. The sympathetic system mainly supports storage by relaxing the detrusor (beta-adrenergic) and tightening the internal sphincter (alpha-adrenergic), while the somatic nerve controls the external sphincter. So, the dominant innervation for the bladder during voiding is cholinergic (parasympathetic) activity.
