  12. 3 main divisions of the brain
    • 1. Forebrain (Prosencephalon)
    • 2. Midbrain (Mesencephalon)
    • 3. Hindbrain (Rhombencephalon)
  13. What is the fxn of cerebrospinal fluid (CSF)
    • Shock absorber

    • 2. Pons
    • 3. Cerebellum
  16. What is the medulla responsible for ?
    Regulates vital autonomic fxns
  17. What is the pons responsible for ?
    • Controls autonomic fxns
    • Coordinates movements
  18. What is the cerebellum responsible for ?
    Complex motor movements
  19. What is the mesencephalon responsible for
    Arousal & wakefulness
  20. What can be found in the mesencephalon
    Reticular Activating System (RAS)

  24. What is the job of the thalamus ?
    Relay & processing for sensory information
  25. What is the role of the hypothalamus ?
    • Major role in hormone production and release
    • Controls emotions and autonomic fxns
  26. What are the parts of the telencephalon
