The relax(es) the muscles. a. muscle fibers b. myofibrils c. golgi tendon organ d. muscle spindles

The answer is c: Golgi tendon organ

The Golgi tendon organ relaxes the muscles.

Explanation:  Golgi tendon organ refers to receptors that are situated in the tendons at the end of a muscle. They are located close to the point of muscular attachment in the tendons. When muscle contraction is excessive, the Golgi tendon organ protects against muscle damage. It also relaxes the muscle.

Muscles are tissues inside an individual’s body which link two bones together. These bones are used for movement. Muscles enable our body to function effectively.
