The
University of Iowa School of Medicine has developed a site with a number of
tissues, both normal and diseased, scanned for virtual microscope viewing.
This is the link to their general site. Choose the Histology Atlas tab on the
main page. You'll figure it out from there.
Indiana
University School of Medicine (IUPUI) offers a great site. It not only
includes systemic and general pathology topics, but you will find a large
normal histology section as well.
The
University
of Utah hosts a fabulous site for teaching pathology, and portions of it
are devoted to normal anatomy and slide staining techniques.
