Didactica3d, Correct Lifting Model, Demonstration Figure, Anatomy (Yelow Pet-G)
When the model lifts the load correctly, bends the knees and straightens the back, all the vertebrae stay together as one and the load is distributed throughout the spine. When lift the load with the legs straight and bend the back, the spine becomes distorted and cracks appear between the vertebrae, which can lead to the appearance of a herniated disc. Clever engineering and assembly have produced a functional figure that provides a graphic demonstration of how the human spine reacts when heavy objects are lifted correctly and incorrectly. Multiple Uses: Designed to better learn about the human body, this model is a great teaching aid for anatomy, biomechanics and physiology. Also a great model of the human body teaching, training, learning, industrial safety, display and office decoration.
