•The nervous system is made up of the brain, spinal cord and nerves. It is the body's communication system that controls much of what your body does. It allows you to do things like walk, speak, swallow, breathe and learn, and controls how your body reacts in an emergency.
•The nervous system controls various organs of the body directly. The brain also receives information from many organs of the body and adjusts signals to these organs to maintain proper functioning. The skeletal system makes up the framework of the body and allows us to move when our muscles contract.
•Nerves carry orders from the brain and spinal cord in the form of electrical signals. Nerves also help sense the state of tissues and relay this information back to the brain and spinal cord, enabling us to experience pain, pleasure, temperature, vision, hearing, and other senses.
