When the Golgi tendon organ is excited, it causes the muscle to relax. The Golgi tendon organs are proprioceptors located at the junction between muscles and tendons, and they monitor tension within the muscle. When excessive tension is detected, such as during heavy lifting or intense contractions, the Golgi tendon organs send signals to the central nervous system to inhibit the muscle activity, leading to relaxation and preventing potential injury. This response is a protective mechanism that helps maintain muscle and tendon integrity by preventing overstretching and damage. By facilitating relaxation, the Golgi tendon organ allows for safer movement and can help in the recovery process of the muscle.
