  25. Arachnoid granulations
    collection of arachnoid villi: in the superior sagittal sinus. Reabsorbs CSF
  26. Falx cerebri

  28. Arachnoid mater
    Avascular layer between the pia and dura mater.
  29. Pia mater
    Thin delicate layer that lies directly on top of the brain
  30. Tentorium cerebelli
    Horizontal divider between the cerebral and cerebellar parts of the brain
  31. Diaphragma sella
    • infundibulum goes thru here
    • Hypothalamus sits on this
  32. Frontal lobe
    • judgement
    • foresight
    • voluntary movement
    • Broca's Area

    motor cortex
  38. Postcentral gyrus
    sensory cortex
  39. Epithalamus
    • Pineal gland
    • Habenula
  40. Thalamus
    relay center
  41. Hypothalamus
    • Temperature regulation
    • emotional responses
    • Salt regulation
    • Food and water intake
    • circadian rhythm
    • memory
  42. Pons
    • works with the medulla for respiratory regulation
    • Relay center for the cerebellum.
    • Pneumotaxic center
    • Sleep
    • Respirations
    • Swallowing
    • Bladder
    • Hearing
    • Equilibrium
    • Face
    • Posture
  43. Medulla
    Regulation of resp and HR
  44. Corpus collosum
    major fiber tract connecting the left and right cerebral hemispheres
  45. Septum pellucidum
