In the context of the parasympathetic nervous system, what effect does it have on the urinary bladder?
Understand the Problem
The question is asking about the effects of the parasympathetic nervous system on the urinary bladder, specifically how it influences the contraction or relaxation of the bladder wall and the state of the sphincters.
Answer
The parasympathetic nervous system causes the bladder's detrusor muscle to contract.
The parasympathetic nervous system stimulates the detrusor muscle of the urinary bladder to contract, facilitating urination.
Answer for screen readers
The parasympathetic nervous system stimulates the detrusor muscle of the urinary bladder to contract, facilitating urination.
More Information
The contraction of the detrusor muscle by the parasympathetic nervous system is crucial for initiating urination.
Tips
A common mistake is conflating the roles of the sympathetic and parasympathetic nervous systems concerning bladder function; the sympathetic system actually maintains bladder relaxation, not contraction.
