Question

Which muscle opens up when we have the urge to pee?

• A. Ureter muscle
• B. Kidney muscle
• C. Sphincter muscle
• D. Rectal muscle

Answer 1

The correct option is C Sphincter muscle

$\bullet$ Sphincters are a pair of circular muscles which control the exit of urine from the body.
$\bullet$ There are two sphincters present, one near the opening of urinary bladder and other in the urethra, called upper and lower sphincters respectively.
$\bullet$ When both the sphincters are open micturition happens, resulting in the removal of urine out of the body.
