2. motor neurons= spinal cord or brain to other parts of the body
3. sensory neurons= body to spinal cord or brain
central nervous system - CORRECT ANSWER✔✔brain and spinal cord
peripheral nervous sytem - CORRECT ANSWER✔✔all the nerves in the body
CNS: four major sections of the brain - CORRECT ANSWER✔✔1. cerebrum= largest part of the brain
(80%), left and right hemispheres
