So let us figure out some
properties of our brains
Run your fingers through your scalp, and feel for bumps
and dents
Make a note of the location of the bumps, and dents
The Nervous System
If you think of the brain as a central computer that
controls all bodily functions
The nervous system is like a network that relays
messages back and forth from the brain to different
parts of the body.
Automatic Nervous System (ANS)
We are often unaware of the ANS because it functions
involuntary and reflexively
we do not notice when blood vessels change size or
when our heart beats faster.
However, some people can be trained to control some
functions of the ANS such as heart rate or blood
pressure
Parasympathetic
Sympathetic
Sympathetic Fight-or-Flight Response
It uses energy
your blood pressure
increases
your heart beats faster
digestion slows down
Parasympathetic
This calls for "Rest and
Digest" responses.
Now is the time for the
parasympathetic
nervous to work to save
energy.
This is when blood
pressure can decrease
pulse rate can slow
digestion can start
Forebrain Largest part of the brain
The cerebrum contains the information that essentially makes us who we are
intelligence, memory, personality, emotion, speech, and ability to feel and move
Specific areas of the cerebrum are in charge of processing these different types of information
These are called lobes, and there are four of them
the frontal, parietal, temporal, and occipital
Midbrain
Smallest area of the brain
Relay station for visual
and auditory information
Also plays a part in body
movement
