Question

Quizplus · Accepted Answer

This reflex is known as the tendon reflex, and it is a protective mechanism that helps prevent muscle and tendon injury. When a muscle is stretched too far, the tendon reflex causes the muscle to relax and lengthen, thereby reducing tension on the tendon and preventing damage. This reflex can be tested by tapping on a muscle tendon (such as the patellar tendon) with a reflex hammer, causing a brief contraction and then relaxation of the muscle.
