Question

Quizplus · Accepted Answer

The urinary bladder does not contract when sympathetic nerves stimulate it. Instead, the sympathetic nerves cause relaxation of the detrusor muscle and contraction of the internal urethral sphincter, which helps to hold urine in the bladder. Contractions of the detrusor muscle are mediated by parasympathetic nerves.
