THE NERVOUS SYSTEM:

ANALOGIES

A Multi-Media Presentation on the Nervous System

Harrison Lee Science A/B

Comparing the Nervous System and Objects

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.

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.

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.

Analogy 4: The Neuron and a Phone The neuron sends messages

along the body which can easily be 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

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.

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

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!

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.
