A teaching model with rounded sizes and angles. Each segment bends by a share of its typical range, with the pelvis held still. Ligament stretch is the change in distance between attachment points, so it is approximate. The disc nucleus shift is exaggerated about three times so you can see it. Real spines vary a lot between people.
Vertebrae are drawn from the same teaching model as the explorer. In the predict items the segment moves after you answer, so you can check your prediction against the model.

Wrong picks are fine here. Each one tells you why.
