Anatomical Model Software

Does anyone know where I can find a program that simulates an anatomical model?

Basically one of these:

but on a computer screen.

Thanks!

Search for Poser, free basic versions exist. Not as intuitive as posing a figure by hand, but will get you a workable figure.

You could also use any of the animation programs, buy a pre-rigged character off of one of the stock sites, and pose it as desired.

Someone created a load of CAD humans for sale recently too (in Solidworks I think). http://www.cadhuman.com/

It depends on what you want to do with it.
