Explanation:
Detailed explanation-1: -When the bladder is empty, the mucosa has numerous folds called rugae. The rugae and transitional epithelium allow the bladder to expand as it fills. The second layer in the walls is the submucosa, which supports the mucous membrane. It is composed of connective tissue with elastic fibers.
Detailed explanation-2: -Lining epithelium: The urinary bladder lining is a specialized stratified epithelium, the urothelium.
