• central nervous system and peripheral nervous system

Which statement best describes the function of the nervous system in the body?  

• to protect other organs and tissues
•  send messages to body parts using only chemicals
• to gather information through the senses (stimuli) and also control all other body systems
• to transport oxygen and carbon dioxide

Which of the following is the nervous system’s main control center?  

• the brain
• the peripheral nerve
• the neuron
