ANATOMY

Detailed explanation-1: -The wall of the bladder is comprised of smooth muscle fibers oriented in multiple different directions. These smooth muscle fibers are collectively known as the detrusor muscle.

Detailed explanation-2: -The muscularis (the detrusor muscle) consists of inner and outer longitudinal layers and a middle circular layer of bundles of smooth muscle separated by fine bands of collagen.

Detailed explanation-3: -Lamina Propria: This is the suburothelial layer separating the urothelium and underlying muscularis propria (detrusor muscle).

Detailed explanation-4: -The next layer is the muscularis, which is composed of smooth muscle. The smooth muscle fibers are interwoven in all directions and, collectively, these are called the detrusor muscle. Contraction of this muscle expels urine from the bladder.

Detailed explanation-5: -The first layer is the lining on the inside of your bladder. The second layer is a thin layer of connective tissue called the lamina propria. The third layer is muscle tissue called the muscularis propria. The fourth layer is fatty connective tissue.
