The document discusses the human nervous system, describing that it is composed of the brain and spinal cord which work together to control organs, coordinate muscle movement, interpret sensory information, and carry messages through neurons. The nervous system is the body's control center and is made up of special nerve cells that connect the brain to the rest of the body and allow impulses to travel quickly, enabling movement and processing of external information.
