Explanation:
Detailed explanation-1: -The spinal cord runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part. This network of nerves relays messages back and forth from the brain to different parts of the body.
Detailed explanation-2: -The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain.
