Detailed explanation-1: -How Does the Nervous System Work? The nervous system uses tiny cells called neurons (NEW-ronz) to send messages back and forth from the brain, through the spinal cord, to the nerves throughout the body. Billions of neurons work together to create a communication network. Different neurons have different jobs.
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. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain.
Detailed explanation-3: -The neurons sense the change and respond to the stimulus by generating electrical impulses. This impulse is transported to the brain by sensory neurons. Brain decodes the impulse and sends a response. This information is transported by motor neurons to the site of action.
Detailed explanation-4: -Nerves are like cables that carry electrical impulses between your brain and the rest of your body. These impulses help you feel sensations and move your muscles. They also maintain certain autonomic functions like breathing, sweating or digesting food. Nerve cells are also called neurons.
Detailed explanation-5: -The autonomic nervous system controls the tone of the digestive tract. The brain controls drinking and feeding behavior. The brain controls muscles for eating and elimination. The digestive system sends sensory information to the brain.
