Quizplus · Accepted Answer

The pontine storage center controls micturition by increasing contraction of the external urethral sphincter and reducing detrusor muscle activity. This allows for the bladder to hold urine until an appropriate time for voiding. Stimulation of the voiding reflex occurs when the pontine micturition center sends signals to the sacral spinal cord, leading to relaxation of the external urethral sphincter and contraction of the detrusor muscle.
