What is the role of the CNS in the release of urine from the bladder?
It decreases the bladder pressure
It decreases the bladder volume
It initiates the contraction of smooth muscles of the bladder
It stimulates the urethral sphincter to relax

The CNS receives signals from the stretch receptors on the walls of the bladder and passes on motor messages to initiate the contraction of smooth muscles of the bladder and the simultaneous relaxation of the urethral sphincter, causing the release of urine.
