  2. Central Nervous System Peripheral Nervous System Nervous System

  3. Brain Review Questions What are the three main parts of the brain?

  4. Brain Review Questions What are the three main parts of the brain? cerebrum cerebellum brain stem

  5. What does the cerebrum control?

  6. What does the cerebrum control? • Higher memory functions • Reasoning • Higher sensory functions associated with listening, vision, and emotions

  7. What does hemispheric dominance mean?

  8. What does hemispheric dominance mean? One hemisphere of the cerebrum is used more frequently than the other.

  9. What does the cerebellum control?

  10. Coordination and voluntary muscular movements. What does the cerebellum control?

  11. What does the brain stem control?

  12. Interconnection of parts of the nervous system Regulation of visceral activities What does the brain stem control?

  13. Nerve Cells

  14. Microglial cells • Protect the nervous system by phagocytosis of bacteria and cell waste

  15. Oligodendrites • Form myelin (lipoprotein) within the brain and spinal cord.

  16. Astrocytes Provide structure and support. Regulate ion and protein concentrations.

  17. Ependymal Cells • Form a membrane around parts of the brain (ventricles and spinal cord).
