The Golgi tendon organ is the receptor that responds to an overload that threatens to tear muscles or ligaments. It is located at the junction of the muscle and the tendon and is responsible for monitoring changes in tension. When the tension becomes too high, the Golgi tendon organ sends a signal to the spinal cord, which causes the muscle to relax and reduces the likelihood of injury. The muscle spindle is responsible for monitoring changes in muscle length and the intrafusal fiber is a component of the muscle spindle. While both of these receptors contribute to proprioception, they are not specifically designed to respond to an overload.
