Detailed explanation-1: -The nervous system includes the brain, spinal cord, and a complex network of nerves. This system sends messages back and forth between the brain and the body.
Detailed explanation-2: -Your nervous system uses specialized cells called neurons to send signals, or messages, all over your body. These electrical signals travel between your brain, skin, organs, glands and muscles. The messages help you move your limbs and feel sensations, such as pain.
Detailed explanation-3: -Without nerve cells, we wouldn’t know if it’s dark or light, hot or cold. We wouldn’t be able to touch anything or feel if someone is touching us. We wouldn’t be able to smell or taste anything and would have no idea that we have an upset stomach or that we have cut ourselves.
