Abstract: A display apparatus is provided which includes a display for displaying at least part of a spine including a plurality of vertebrae and for displaying a plurality of organs and a nerve system. The organs and nerve system are physiologically associated with the vertebrae. The display includes a light penetrable support on which the vertebrae and organs are displayed. A plurality of light generating devices are employed for selectively illuminating respective of the vertebrae and organs. There are provided a plurality of control switches which are connected in a circuit to the light generating devices for the illumination of the vertebrae and organs as well as the nervous system. An electronic computer is coupled to the control switches and to the circuit and is responsive to the control switches for the selection and automatic sequencing of illumination of light generating devices to create movies.

Abstract: A display apparatus is provided which is divided into two frames. On one frame is pictured a human body with the spinal column thereof formed of a plurality of vertebrae. The human body displayed also includes a plurality of organs and the like which are associated, according to Gray's Anatomy, with the various vertebrae. Push-button controls are positionally related to the vertebrae and when operated could cause an illumination of the related organs. A further series of push-button controls are provided in order that the organs can be separately illuminated as desired. Arrangement is made so that the illumination can be steady state or pulsating fashion selectively. On the second of the aforesaid frames is visually displayed a set of front and rear views of the human body and the related musculature. Push button controls are arranged for the illumination of the various muscles. These latter push-button controls are coupled to one of the aforesaid sets of controls for interaction therewith.
