Answer:
Sometimes your body responds to a situation before your brain makes a conscious decision. For example, if you touch a hot stove accidentally, the electrical impulse immediately begins to travel from neuron to neuron until it reaches the spinal cord. Before the impulse passes on to the brain, an automatic message is sent back to your hand, telling your muscles to move your fingers away from the hot stove.
While this is happening, the impulse continues to the brain. Your brain interprets the message, and you realize that your are touching something hot and should move your hand. Since the whole process happens so quickly, you do not notice the time difference. From the time you touch the stove until you move your hand and your brain registers what has happend, less than one-thousandth of a second has passed.
Even though this seems to happen all at once, you actually pull your hand back before your brain tells you that there is pain. This is called a reflex. A reflex is an action that happens before the brain has time to think about the action. A reflex is hard, sometimes impossible to control.
Tried my best to explain,
