            By:
Andrew Baccaro & Robert Keller
                    Cerebrum
 Largest part of the human brain
 Divided into 4 sections
       High brain functions such as thought and
        action
           Temporal Lobe
 Associated with emotional responses,
  hearing, memory and speech
 Anterior to the occipital lobes
 Lateral to the Fissure of Sylvius
                Occipital Lobe
   Controls vision and
    color recognition
   Most caudal portion of
    the cerebral cortex
                Parietal Lobe
   Controls cognition,
    information process,
    pain and touch
    sensation, spatial
    orientation, speech,
    and visual perception
   Superior to the
    occipital lobes
   Posterior to the
    fissure and frontal
    lobes
                  Frontal Lobe
   Controls motor
    functions, higher
    order functions,
    planning, reasoning,
    judgment, impulse
    control, and memory
   Anterior portion of the
    cerebral cortex
     Cerebellum (little brain)
 Important role in motor control
 Helps provide smooth, coordinated body
  movements
       Cerebellum Anatomy
 Most neurons than rest of brain combined,
  only 10% of brain volume.
 Made up of very tightly folded layer,
  cerebellar cortex.
 If unfolded, would be 1 meter long and 5
  cm wide.
Cerebellum Structure
             A: Midbrains
             B: Pons
             C: Medulla
             D: Spinal Cord
             E: Fourth Ventricle
             F: Arbor vitae
             G: Tonsil
             H: Anterior Lobe
             I: Posterior Lobe
              Medulla Oblangata
   Located above the
    spinal cord, below the
    pons, and anterior to
    the cerebellum
   2 parts
       Open part (close to
        pons)
       Closed part (further
        down by spinal cord)
Medulla cont.
          Controls autonomic
           functions, and relays
           nerve signals
           between the brain
           and spinal cord.
          Controls several
           major points and
           autonomic functions
           of the body
              Respiration, blood
               pressure, swallowing,
               vomiting, defecation.
