The document presents a multi-media presentation that compares the nervous system to various objects through a series of eight analogies: 1) the brain and computer, 2) the nervous system and electrical system, 3) the brain and a hospital, 4) the neuron and a phone, 5) the cerebrum and a computer, 6) the dendrites and phone operators, 7) the reflex and an anti-virus program, and 8) sensory nerves and heat sensors. The presentation utilizes images and videos from sources like BrainPOP and links to provide visual examples and further explanation for each analogy between biological and technological systems.

1. A Multi-Media Presentation on the Nervous System
Harrison Lee Science A/B
Comparing the Nervous System and Objects

2. Analogy 1: The Computer and
the Brain
 The computer is the central place where
everything is in control. Like the brain they
both control their systems and do whatever
to protect them. Examples are, the brain
shutting down so somebody can fight
disease, alike the computer shuts down to
protect the computer from viruses before
they reach the system.

3. Analogy 2: The Electrical
System and the Nervous
System
 The Electrical system of a big building can
be easily related to the nervous system of
our bodies since the electrical system sends
commands throughout the wires and the
nervous system as it also sends messages
throughout the body.

4. Analogy 3:The Brain and a
Hospital
 The brain like a hospital works alike.
Patients in a hospital send messages
for help just how a brain sends
messages to parts of the body to warn
them of incoming threats.

5. Analogy 4: The Neuron and a
Phone
Click on these buttons below to
 The neuron sends messages listen to a more detailed
along the body which can easily be explanation
connected to how a phone sends
messages to other people. In
analogy 6, more information will be
revealed on how the neuron really
is like a phone. Skip to Analogy 6

6. Analogy 5: The Cerebrum and
a Computer
 The cerebrum acts the
thinking part of the nervous
system just as the computer is
the part of the computer
system that does all the
processing and the thinking.

7. Analogy 6: The Dendrites and
Phone Operators
 The dendrite plays the role of being
the phone operator of the nervous
system. The dendrite receive
impulses from neurons and send
them away to the cell bodies. This
can also relate in analogy 4, as you
can see how dendrites, impulses,
and neurons are like a telephone.
Just how you call on the phone and
the operator directs you to the
correct place to call. Back to
Analogy 4

8. Analogy 7: The Reflex and an
Anti-Virus Program
 A reflex is an involuntary, automatic response
to a stimulus, or something that influences a
certain activity. Anti-Virus programs are
programs on a computer that protect your
computer from harm that comes from viruses.
A reflex in the same way protects your body
when you touch something sharp, hot, or cold.
It sends messages to you to warn you just like
an anti-virus program that sends messages to
warn you about a virus!
An antivirus
program
giving an
alert on a
suspicious
<<<program.
A doctor testing
its patient’s
reflexes with a
reflex hammer
to see how its
body reacts.>>>

9. Analogy 8: Sensory Nerves and
Heat Sensors
 Sensory nerves are nerves that sense whatever
the nerve is touching. It sends messages to your
brain telling you what something feels like. Rough,
soft, smooth, hard, hot, or cold. Heat sensors also
sense if something is hot or cold. But nothing else
then heat.
