This project from the University of Texas at Austin is an interactive approach to learning anatomy. Users choose either to view human, baboon, or gorilla skeletons to learn about individual bones, or compare the anatomy between species. Bones can be rotated and viewed from different angles, along with various "'overlays' depicting major muscle origins and insertions as well as articulations and morphological features." Additional three-dimensional features can be viewed with Quicktime and VRML plug-ins that can be downloaded from the site. The glossary of anatomical terms is quite helpful, incorporating images along with textual definitions.
