• The brain is made up of about 75% of water.
• It is the FATTEST organ of the body; Consists of at least 60%
fat.
• 100,000 miles of blood vessels are inside of the brain.
• Our brains contains no pain receptors which means it can feel
no pain.
• The Cerebrum is the largest part of the brain, and makes up
about 85% of the brain’s weight. ( a human brain is about 3
pounds).

• Information can be processed as
slow as .5 meters/sec or as fast
as 120 meters/sec ( about 268
MPH).
• While awake, the brain can can
generate between 10-23 watts of
power which is enough to power
a lightbulb.
• The Neocortex of the brain
makes up 76% of the brain. It is
responsible for our language and
consciousness.

8. • Frontal lobe (pink) is responsible for
thinking and planning.
• Temporal lobe (green) is in charge of
sound, music, face/object recognition,
and some long-term memory. It is also
the house of speech centers but
usually only found of the left side.
• Occipital lobes (purple) are for the
visual processing.
• Parietal lobes (yellow) control the
spacial orientation, calculations and
certain types of recognition.

10. Brain Stem
11 of our 12 nerve endings
end in our brain stem. Our
heart beat, body temperature
and digestion are monitored
and controlled in our brain
stem.
It also houses the (RAS),
reticular activating system,
which controls the brain’s
alertness.

Representing nearly 80% of
the brain is the Cerebrum.
Here is where the left side
of the nerves cross over to
the right and vice versa.
Memory, speech, thinking
and muscular movement
take places in the cerebrum.
