Abstract
A demonstration device for illustrating spinal injury utilizing a demonstration model of a portion of a human spine in which visual electronics have been applied through the use of light emitting diodes to show the interruption of nerve signal flow upon the dislocation of the vertebrae bones with relation to one another. The device includes an electric circuit, battery, and a switch which operate upon rotation of the model to change the rate of flash of light emitting diodes thus indicating a change in nerve frequency due to injury.
