Some Random Nervous
System Trivia
• Two Parts of the Nervous System
• Central Nervous System CNS (blue)
– Brain and spinal cord
– Control center
• Peripheral Nervous System PNS
(pink)
– Made of nerves that transmit
information in the form of
electrical impulses from the CNS to
the rest of the body
• Brain is protected by skull
• Avg. size of adult human brain: 3
pounds
Brain is divided into 3 MAJOR Parts
• Cerebrum
– Orange, wrinkly
walnut looking part
• Cerebellum
– Blue cauliflower
looking thing
• Brain Stem
– Brown stem looking
thing
Cerebrum
• Largest part of brain
• Divided into 2 “cerebral
Hemispheres”
• Each hemisphere is divided
into 4 LOBES (FPO-t)
– Frontal
– Temporal
– Parietal
– Occipital
Match the picture with the lobe! (might match more than one!)
A. Frontal
reasoning, planning, parts of speech,
movement, emotions, and problem
solving
B. Temporal
associated with perception and
recognition of auditory stimuli,
memory, and speech
C. Parietal
associated with movement,
orientation, recognition, perception of
stimuli
D. Occipital
associated with visual processing

Cerebellum
• Second largest part of brain
• “little brain”
• JOB:
– Coordinate Movements
– Posture
– Maintain balance
– Damage or injury to the part of
this brain will make your
movements jerky and
uncoordinated
Brain Stem
• Three MAJOR Parts (M-P-M):
– Midbrain
– Pons
– Medulla Oblongata
• Controls MOST important
functions that keep us alive
• Automatically controls:
–
–
–
–
Breathing
Heartbeat
Blood pressure
Circulation
• Imagine if this wasn’t controlled
automatically???
• What if you forgot to breathe??
Def NOT good!
Brain Stem
• Midbrain
– Voluntary motor
function
– Vision
– Hearing
– Eye movement
– Body movement
• Pons
– Motor control
– Sensory analysis
• Medulla Oblongata
– Maintains VITAL body
functions
• Breathing
• Heart rate
Everything You Need To Know
Cerebrum
Know the Different Views
Right Brained vs. left Brained
• Right side of the brain is
connected to the left side of
the body
• Left side of the brain is
connected to the right side of
your body
• Reason:
– the nerves connecting the
brain and the spinal cord
cross to the opposite side.
• Right handed people depend
on left side of brain
– Good at solving problems,
math, language, analytical
• Left handed People depend on
right side of brain
– good in music, art, creativity,
story telling
