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.
