The '''urethralis''' muscle runs the entire length of the urethra and forms the external urethral sphincter.

Unlike the [[Bladder - Anatomy & Physiology#Internal Urethral Sphincter|internal sphincter]] the external sphincter is composed of striated muscle fibres which are under the voluntary control of the somatic nervous system.
