A.d.a.m.

I used it and found it very helpful. I ordered the ADAM Anatomy CD-ROM and the Physiology CD-ROM. They were bundled together and sold by Journey Ed (www.journeyed.com) at a very reasonable price. You'll have to fax them a copy of your student ID in order to get the discount (they knock a few hundred off the retail price).

The ADAM Practice Practical is so so.

 

Well, I thought the ADAM to be somewhat marginal in utility.

The Voxel-Man (Brain/Skull, Inner Organs) by Springer is, in my opinion, pretty amazing.

You can explode, fly through, slice, and all sorts of other good stuff. The program is 3-D and based on real cadavers. It has radiologic correlations too.
