Everyone knows that the brain is responsible for our smarts and the spinal cord holds us up, but students may be surprised to learn how much more these powerhouses are responsible for. Together they control the nervous system. Without them, we would not be able to think, remember, digest nutrients, breathe, blink, swallow, and so much more. Featuring clear and arresting 3D illustrations, this volume takes readers through the brain and spinal cord, covering their parts and functions, and serves as a comprehensive introduction to the human body.
