Quizplus · Accepted Answer

The stretching of the bladder wall sends signals to the central nervous system, specifically to the pontine micturition center, which triggers the reflex to initiate micturition (voiding). The pressure of fluid in the bladder is a result of the stretching of the bladder wall, so it is not the primary trigger for micturition. The sympathetic efferents and motor neurons may be involved in the process, but they are not the trigger for initiation of micturition.
