Answer:

☆A sphincter is a muscle that surrounds a body opening (the urethra or the anus, for example) and which should unconsciously remained tightly closed.

☆ During urination, sphincters relax and open when messages are relayed from your nerves and your brain to the pelvic floor muscles.

☆ Internal and external sphincter muscles control the storage and voiding of urine.

☆The internal sphincter instinctively squeezes the urethra closed.
