Detailed explanation-1: -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.

Detailed explanation-2: -The urinary bladder (UB) has two key functions: to store and void urine. Voiding occurs through the coordinated contraction of detrusor smooth muscle cells in the bladder wall.

Detailed explanation-3: -The wall of the ureter consists of three layers. The outer layer, the fibrous coat, is a supporting layer of fibrous connective tissue. The middle layer, the muscular coat, consists of the inner circular and outer longitudinal smooth muscle.

Detailed explanation-4: -At a cellular level, smooth muscle can be described as an involuntary, non-striated muscle. Smooth muscle consists of thick and thin filaments that are not arranged into sarcomeres giving it a non-striated pattern. On microscopic examination, it will appear homogenous.
