Final answer:
The events of continence involve the storage of urine and the first urge to void. Voluntary control of urination is important for maintaining urinary continence. As the bladder fills, subsequent urges to void become harder to ignore and can lead to incontinence.
Step-by-step explanation:
The events of continence - storage and first urge to void - are part of the process of urination or voiding, also known as micturition. When the bladder volume reaches about 150 mL, an urge to void is sensed. Voluntary control of urination relies on consciously preventing relaxation of the external urethral sphincter to maintain urinary continence. As the bladder fills, subsequent urges become harder to ignore, and voluntary control eventually fails, resulting in incontinence.
