Final Answer:
The reflex triggered by Tendon Organs detecting excessive contraction in muscle is the Golgi tendon reflex, promoting muscle relaxation to prevent injury.
Step-by-step explanation:
The Golgi tendon reflex is a protective mechanism that comes into play when the Tendon Organs, located in the musculotendinous junctions, sense heightened muscle tension. These organs detect changes in muscle length and tension during contraction. If the contraction becomes too forceful, signifying a risk of injury, the Golgi tendon reflex is activated. This reflex involves inhibitory signals sent to the spinal cord, resulting in the relaxation of the contracting muscle. By inducing muscle relaxation, the Golgi tendon reflex prevents the muscle from sustaining damage due to excessive force, contributing to the overall safety and integrity of the musculoskeletal system.
