JayDoc HistoWeb, provided by two medical students at the University of Kansas, is a frames-based site that provides hundreds of microscopic anatomical images, topically arranged in 19 categories ranging from blood & bone marrow to vascular system. Each image is accompanied by a short annotation and scale bar. Interested users have the option of clicking a button for a much larger view. Note that though this site is extremely graphical and may be a challenge to those with slow connections, it is a treasure house of anatomical information.
