Question

Quizplus · Accepted Answer

The Golgi tendon reflex is responsible for preventing excessive tension in a muscle by causing it to relax when there is too much force generated. This is accomplished by the Golgi tendon organ, a sensory receptor located in the tendon, which detects changes in tension and sends signals to the spinal cord to inhibit the motor neurons that innervate the muscle. The stretch reflex (A) is responsible for maintaining muscle tone and preventing overextension of a muscle. The withdrawal reflex (B) is a protective reflex that causes a limb to be pulled away from a harmful stimulus. The reciprocal reflex (D) is involved in coordinating agonist and antagonist muscles during movement. The crossed extensor reflex (E) is also a protective reflex, but it causes the opposite limb to extend when the other limb is withdrawn.
