PATHOLOGY

Detailed explanation-1: -The primary function of the detrusor muscle is to contract during urination to push the urine out of the bladder and into the urethra. The detrusor muscle will relax to allow the storage of urine in the urinary bladder.

Detailed explanation-2: -The urothelium is thick with five to seven structural layers when the urinary bladder is relaxed. However, the bladder wall stretches to accommodate the increased volume when the urinary bladder fills with urine. The urothelium reorganizes into two or three layers in the distended bladder without structural damage.

Detailed explanation-3: -The brain tells the bladder muscles to squeeze (or “contract"). This forces the urine out through your urethra, the tube that carries urine from your body. Your urethra has muscles called sphincters.

Detailed explanation-4: -Abstract. The detrusor smooth muscle is the main muscle component of the urinary bladder wall. Its ability to contract over a large length interval and to relax determines the bladder function during filling and micturition.
