Detailed explanation-1: -The detrusor muscle is located within the walls of the bladder and is composed of smooth muscle fibers that are longitudinal and circular. The layers of the detrusor muscle start longitudinally in the inner layer, become circular in the middle layer, and then longitudinal again in the outer layer.

Detailed explanation-2: -The detrusor muscle is 3 layers of smooth muscle. The fibers of the smooth muscle include both longitudinal and circular and the layers of the detrusor are as follows: inner layer: longitudinal fibers. middle layer: circular fibers. outer layer: longitudinal fibers.

Detailed explanation-3: -The detrusor is the smooth or involuntary muscle of the bladder wall. The urethral muscles consist of the external and internal sphincter. The internal sphincter and detrusor muscle are both under autonomic control. The external sphincter, however, is a voluntary muscle under the control of voluntary nerves.
