Human spine model with a plurality of rigid disks each having radial
elongate members that represent vertebrae, a plurality of resilient disks
that represent spinal disks and a plurality of elastic band members that
represent connecting muscle, all mounted on top of a housing. The rigid
disks are alternately interspersed with the resilient disks thereby
forming a column. The rigid disks and the resilient disks each have a
centrally located aperture. The resilient disks are translucent and each
have an LED imbedded within. When a rotary knob is rotated by a user a
take up spindle within the housing pulls on a flexible cable traveling
through the center of the disks causing a pre recorded audio message and
the LED's to activate and causing the resilient disks to compress and
bulge outward. The elastic bands connect one elongate member to another
simulating muscle tissue.
