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.
In men, the urethra is longer and is encircled by the prostate, which is a gland that is part of the reproductive system. Urination occurs when the urinary sphincter muscle relaxes and the bladder muscle contracts to expel the urine. The bladder consists of three layers. The inner lining layer of the bladder, called the mucosa, is formed by a type of cell called transitional cell. The next layer, the lamina propria, provides support to the mucosa. The third layer is the bladder muscle itself.
