Draw and label a diagram of a reflex arc
- The pain withdrawal reflex is an involuntary action in which the body reacts to pain by trying to move itself away from the source of the pain.
- The response is so fast that if you step on a sharp object with your right foot, the pain withdrawal reflex will cause you to lift your right leg before your brain perceives pain.
- In the leg example, the effector muscles in your right leg are flexors, which bend the right leg when they contract.
