Flash Animations and Illustrations
The following simple illustrations and interactive flash animations were developed as visual aids to describing complicated biochemical processes and tissue architecture.
When indicated, the animations may be imported into PowerPoint presentations.
These are free to use for not-for-profit organizations. If used in a presentation, please give a short citation:
