Question

Quizplus · Accepted Answer

The Golgi tendon organ is responsible for sensing changes in muscle tension. When the weightlifter holds a heavy weight, the tension in the muscles and tendons increases significantly. If the tension becomes too high, the Golgi tendon organs are activated to prevent potential damage to the muscles or tendons by initiating a reflex that causes the muscle to relax. This is why the weightlifter suddenly drops the weight.
