How accurately does this skeleton move? I'm looking for a skeleton to teach kinesiology, so it's important that it move correctly. Many have just fixed spines and ribs, and hands & feet that flex at the wrist and ankle but are otherwise fused. This looks like a better model than those, but I'd love some specifics of exactly what it does and doesn't have. Also, if there's a more appropriate one more my needs in the same price range (or less) please let me know.

The models that are described as Budget offer many features that are necessary for basic study. This particular model does offer basic movement through the major joints, but is not considered a kinesiology specific model. We do offer flexible skeletal models that offer shoulder blade rotation, flexible spines, ulnar/radius rotation, knee flexion etc however the price range of these units is typically $700-$1200 as the complexity of the movement increases. In the Budget price range, we do not offer skeletal models that offer a full range of motion.
