Virtual Slide List for Histology Course

Browse the complete collection of the UM slides (more than the histology course collection)
compiled by Kent Christensen, Ph.D., J. Matthew Velkey, Ph.D., Lloyd M. Stoolman, M.D., Laura Hessler, and Diedra Mosley-Brower

curated by Michael Hortsch, Ph.D. If you have questions or comments regarding the University of Michigan virtual slide collection, please contact Dr. Hortsch at hortsch@umich.edu 

Some items in the list contain numbers in brackets that give coordinates where you can find a good example of a specified structure on that slide. These X, Y coordinates can be read at the bottom of the computer screen when you view a virtual slide with the ImageScope. The coordinates indicate the exact location of the mouse pointer at a given moment. To view a structure indicated by the bracketed XY coordinate numbers in the list, go to the Tools (or Image) menu, click “Go To …”, and then enter the two coordinates (X and then Y). Click “Go To: Center,” and then “Close,” The item will be in the center of the screen, and you can view it at any magnification you please.
