Transcript of Katie's Nervous Security System

The Cell Body contains the Nucleus and 2 extentions
Cell Body (Power Supplies)
Katie's Nervous Security System
Dendrites are shorter, more numerous, and receive information.
Dendrites (RF Wireless Receivers)
Neurons are masses of nerve cells that transmit information.
Neuron (Dialer's Voice & Cellular)
The Axon is a single, long "fiber" which conducts impulse away from the cell body and sends information.
Axon (Hardwire Contacts)
The speed of the impulse is proportionate to the diameter of the axon. (Greater diameter=faster speed)
Impulse (Wireless Transmitters)
The CNS is an integrating and command center which consists of the brain and spinal cord.
Central Nervous Center (alarm modules)
The PNS include 12 pairs of cranial nerves and 31 pairs of spinal nerves.
Peripheral Nervous Center (Sirens, Speakers, and Strobes)
How does the Nervous System relate to a modern day security system?
A nervous system has sensory information as well as a security system. Cameras to see like the eyes, sensors to detect motion, like touch, microphones, etc. All of this information is transmitted from the device (or sensory organ) back to a central server (like the brain). The network whether it be fiber optics, copper cables, or wireless is like the nerve pathways in the body. The information is then processed electronically to cause a reaction like turning on an alarm (sort of like a reflex).
