Detrusor muscle. The detrusor muscle is a layer of the urinary bladder wall made of smooth muscle fibers arranged in spiral, longitudinal, and circular bundles. When the bladder is stretched, this signals the parasympathetic nervous system to contract the detrusor muscle. This encourages the bladder to expel urine through the urethra.
Structure. The bladder wall is made up of 3 layers. 1  The urothelium lines the inside of the bladder, ureters and urethra. 2  It is made up of urothelial cells, or transitional cells. 3  It is also called the transitional epithelium. 4  The lamina propria is a layer of connective tissue. The lamina propria is also called suburothelial connective tissue or subepithelial tissue. 2  The muscularis is the outer layer of the bladder. 3  It is made up of 3 layers of smooth muscle tissue (bladder muscle) called the inner longitudinal, middle circular and outer longitudinal muscles.
