I'm geussing at the purpose of big_dave's original query, softriver, which is why I confined my little paragraph up there to "Poser Used as Artistic Reference." I do believe I may have said as much in my topic sentence, although you might have missed it. It's an interesting subject, the proper simulation of anatomy (static or not). I thank you for the links above. To be able to better direct this thread, however, I think we need to hear more from big_dave about his specific needs.
