Heading: Basic Operation of Bladder

Text: The bladder is part of the urinary system; its purpose is to store urine until it is voided from the body. In a functional urinary system, the distal sphincter muscle controls when urine exits the bladder. Once the bladder is full, nerve fibers in the bladder are triggered. These nerve fibers meet with other nerve fibers serving other parts of the body to form a nerve, i.e., [a] bundle of nerve fibers. Taber's Cyclopedic Medical Dictionary 1280 (18th ed.1997). The message that the bladder is full is transmitted along this nerve to the spinal cord and then to the brain. When the individual decides to act on the sensation that the bladder is full, the brain sends a message to the distal sphincter muscle telling it to relax. The muscles surrounding the bladder then contract and force the stored urine into the urethra and out of the body.
