Introduction:
The urine is stored in the urinary bladder, which releases the urine via the urethra. Urination is controlled by the sphincter muscles that are present in the urinary bladder. Urination is also known as voiding or micturition.
Explanation of Solution
The term urination is also medically known as micturition. It depends on two spinal reflexes that are the urine voiding and storage reflex. When the urinary bladder contracts, it forces the urine to come out of the body via the urethra. The sphincter muscles that are present in the urinary bladder control the expulsion of the urine.
Therefore, it can be concluded that the urination can be correctly matched with option (c) micturition.
