Final answer:
Lack of control of urination is known as urinary incontinence, which is described as uncontrolled leakage of urine and may severely affect an individual's quality of life.
Step-by-step explanation:
The term that means lack of control of urination is D. Incontinence. Urinary incontinence is an issue where there is uncontrolled leakage of urine, which can be due to various reasons including weak bladder muscles, nerve damage, or an enlarged prostate gland.
The micturition reflex involves both voluntary and involuntary actions, and as the bladder fills up the urges to void increase. When bladder volume reaches a certain point, typically 300 to 400 mL, the voluntary control may fail, and urinary incontinence may result. This condition can significantly impact an individual's quality of life, causing inconvenience, embarrassment, and distress.
