Question

The reflex that causes muscle relaxation and lengthening in response to muscle tension is called a tendon reflex. When a muscle contracts, it pulls on its associated tendon, which activates sensory receptors called Golgi tendon organs (GTOs). These GTOs then send signals to the spinal cord where inhibitory interneurons cause a reflex relaxation of the muscle. This helps to prevent excessive tension and potential injury to the muscle.
