Final answer:

The urge to urinate is caused by various factors like stretch receptors and increased bladder pressure, involving the detrusor muscle.


Explanation:

The urge to urinate is caused by stretch receptors in the bladder wall that signal when the bladder needs to be emptied. This sensation is also triggered by increased bladder pressure as it fills up, stimulating the micturition reflex. The detrusor muscle in the bladder wall, controlled by the nervous system, plays a crucial role in initiating the process of urination.
