Detailed explanation-2: -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-3: -The three major functions of the nervous system are; Gathering sensory information from body and external environment. Processing and interpreting the sensory information received. Conveying appropriate response to the sensory information received.
