  2. 2 Divisions Central Nervous System: consists of the brain and spinal cord Peripheral Nervous System: includes nerves located outside of the central nervous system

  3. Central Nervous System

  4. Peripheral Nervous System

  5. Central Nervous System Control center of the body Brain: controls functions in the body Spinal Cord: (link between your central and peripheral nervous system

  6. Brain

  7. Spinal Cord Top view on right Side view below

  8. Brain and Spinal Cord 3 major regions of the brain receive and process information Cerebrum – interprets input from the senses, controls movement, & carries out complex mental processes

  9. Cerebrum

  10. Cerebellum-coordinates balance and helps balance Brain Stem-between cerebellum and spinal cord, controls involuntary

  14. Daily body functions: Digesting food, your heart Beating, hormones sent to A variety of endocrine glands, Etc. IS THIS SOMATIC OR AUTONOMIC?
