ANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -What Is the Central Nervous System? The central nervous system is made up of the brain and spinal cord: The brain controls how we think, learn, move, and feel. The spinal cord carries messages back and forth between the brain and the nerves that run throughout the body.

Detailed explanation-3: -Motor neurons carry messages away from the brain to the rest of the body. All neurons relay information to each other through a complex electrochemical process, making connections that affect the way you think, learn, move, and behave. Intelligence, learning, and memory.

Detailed explanation-4: -Together, the brain and spinal cord form the central nervous system. This complex system is part of everything we do. It controls the things we choose to do-like walk and talk-and the things our body does automatically-like breathe and digest food.
