Quizplus · Accepted Answer

The three layers of the muscular layer of the urinary bladder are collectively known as the detrusor muscle. The external urethral sphincter and internal urethral sphincter are separate muscles that control the release of urine from the bladder, while the trigone is a triangular area in the bladder where the openings of the ureters and the urethra meet. The ductus deferens is a part of the male reproductive system and is not related to the urinary bladder.
