  1. Divisions of the Nervous System Central Nervous System Peripiheral Nervous System

  2. Central Nervous System Control Center of Body Consists of the : Brain and Spinal Cord

  3. Brain Part of Central Nervous System (CNS) located in skull. Controls most body functions. Contain 100 billlion interneurons

  4. Cerebrum One of 3 main sections of the brain. Largest Part of Brain Interprets input from senses--- controls movement (voluntary muscles--- carries out complex mental processes (learning/remembering)_

  5. Cerebellum Second largest part of brain Coordinates actions of your muscles and helps you keep your balance

  6. Brain Stem Midbrain-Pons-Medulla Oblongota Located between the cerebellum and spinal cord Heart Beat Controls your body's involuntary actions Breathing Blood Pressure Sleep

  7. Spinal Cord Thick column of nervous tissue that links the brain to most of the nerves in the peripheral nervous system.

  8. Peripheral Nervous System Series of nerves that branch out from the central nervous system and connect to the rest of the body

  9. Somatic Nervous System Nerves of the pheripheral nervous system that control voluntary actions

  10. Autonomic Nervous System Part of the Peripheral Nervous System that controls Involuntary Actions

  11. Reflex Automatic response that occurs rapidly without conscious control to protect the body Does Not involve the Brain=no thinking

  12. Concussion A bruise like injury of the brain. Occurs when soft tissue of brain collides against the skull.

  13. Spinal Cord Injuries • When it is cut or crushed. Can result in paralysis

  14. Brain

  15. Study Key Terms
