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. Different neurons have different jobs.

Detailed explanation-2: -NERVOUS SYSTEM PRIMARY PURPOSE: Control Center: transports messages to/from the Brain! PRIMARY ORGANS: Brain, nerves, neurons, spinal cord (main connection coming out of the brain to the rest of the body’s nerves) (1) Sends messages to the entire body from the Brain.

Detailed explanation-3: -The spinal cord is the information superhighway that connects the brain with the rest of the body through its connections with peripheral nerves. It transmits sensory and motor input and also controls motor reflexes.

Detailed explanation-4: -It guides everyday activities such as waking up; automatic activities such as breathing; and complex processes such as thinking, reading, remembering, and feeling emotions. The nervous system controls: Brain growth and development. Sensations (such as touch or hearing)

Detailed explanation-5: -What does the nervous system do? 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.
