ANATOMY

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 nervous system includes the brain, nerves and spinal cord. It is the communication center for the body, sending and receiving messages, regulating body functions and serving as the control center for the five senses and for emotions, speech, coordination, balance, and learning.

Detailed explanation-4: -The human nervous system controls all activities of the body in a quicker fashion. It can be divided into the central nervous system and peripheral nervous system. The central nervous system includes spinal cord and brain and the peripheral covers the nerves branching from spinal cord and brain.

Detailed explanation-5: -Neurons are information messengers. They use electrical impulses and chemical signals to transmit information between different areas of the brain, and between the brain and the rest of the nervous system.
