E) Free nerve endings

Question

Quizplus · Accepted Answer

Golgi tendon organs are specialized receptors located in tendons that are sensitive to changes in muscle tension. When there is a large increase in tension on a muscle, the Golgi tendon organs will send signals to the spinal cord, which will in turn decrease the rate of firing of the muscle fibers to prevent damage. This protective reflex is known as the Golgi tendon reflex.
