lumbar vertebra anatomical model / for teaching / child
Area of the body:
This model was constructed with the curious child in mind who is interested in understanding how the spine works. Constructed with a viscoelastic annulus and nucleus, an added feature of a smiley face is within the nucleus to show internal movement. A small tiny tear is also represented within the inner annulus to show that annular fissures can occur in a young spine. This model can be helpful in the teaching of early principles of lifting mechanics before bad habits set in.
