Quizplus · Accepted Answer

The mucosa with its rugae is the innermost layer of the urinary bladder that contains folds which permit expansion without tearing the lining. The trigone is a triangular area in the bladder formed by the openings of the ureters and urethra. The detrusor muscle is the smooth muscle layer of the bladder wall responsible for contraction during urination. The serosa is the outermost layer of the bladder. None of these structures are responsible for permitting expansion without tearing.
