Why does the spinal cord play a bigger role than the brain when the hand is pulled back after touching a hot object?

Answer and explanation

Correct answer: Because the spinal cord produces a quick reflex response

The governing concept is reflex action, a rapid, automatic protective response. Heat stimulates pain receptors in the skin; sensory neurons carry the impulse to the spinal cord, where an interneuron connects it to a motor neuron. The motor neuron activates arm muscles before the brain has fully analysed the sensation, so withdrawal is quick. The brain later receives information and becomes aware of pain. The other options deny normal nerve or muscle function.
