Urethra: Tube for expelling urine from the bladder
Urethra: The tube that carries urine from the bladder to the outside of the body. 1
Introduction: When you urinate, the brain signals the bladder muscles to tighten, squeezing urine out of the bladder. At the same time, the brain signals the sphincter muscles to relax. As these muscles relax, urine exits the bladder through the urethra. When all the signals occur in the correct order, normal urination occurs. 2
