External Urethral Sphincter: Function & Location

The voluntarily controlled sphincter fashioned by skeletal muscle at the point where the urethra passes through the pelvic floor is called the external urethral sphincter. It is one of the two sphincters that control the flow of urine from the bladder. The other sphincter is the internal urethral sphincter, which is located at the base of the bladder and is made up of smooth muscle.
