The Golgi tendon organ is a nerve receptor that is located at the muscle-tendon junction. These receptors sense tension and relays a signal to the spinal cord. The spinal cord then signals the stretching muscle to relax. This reflex arc acts as a protective circuit breaker to prevent the tendon from tearing at its attachment to the bone. Because all skeletal muscles have Golgi tendon organs, this powerful technique can be applied to gain length throughout the body
