I bent her over and looked just now. No vertebrae anywhere. The muscles on either side remain just as they are when standing, so that the spine is a "valley" in all positions. No tendons on the hands either. But I will say this for DAZ: the inner construction of the head is excellent. I've been building an image for my anatomy work, and found that V3's mouth, tongue, and inner nasal surfaces are very accurately designed. When I mount a DAZ skull inside the head, and then fit in my own larynx and trachea model, all the shapes come out right.
