Abstract:
A metal panel carries views depicting a human spine. A plurality of movable pieces corresponding in shape to vertebrae or disks depicted on the panel are provided with magnet means, so that the pieces may be placed to overlie vertebrae areas on the panel to illustrate normal spinal conditions, and may be shifted on the panel to illustrate abnormal conditions.
