== Introduction ==
Histology is the study of the microscopic structure of biological material and the ways in which individual components are structurally and functionally related. It is central to medical science since it stands at the crossroads between biochemistry, molecular biology and physiology on the one side, and pathologic processes that cause disease on the other. Although often thought of as an archaic discipline, practical knowledge of histology is in actuality an integral part of modern investigative techniques and current medical practice
## '''Toluidine blue'''. Used to demonstrate granules in mast cells. Nuclei are deep blue; mast cell granules are reddish-purple.
## '''Verhoeff-Van Gieson stain (VVG)'''. This method is used for identifying elastic fibers in tissues such as skin, aorta, etc. The elastic fibers will be stained blue-black and background will be stained yellow.
== Using Histologic ==
[[Histologic]] is a constantly-updated, wiki-based comprehensive manual for the teaching of histology. It integrates still images from the [{{SERVER}}/library PEIR Digital Library] and whole slide images from the [http://peir-vm.path.uab.edu PEIR-VM] project. Still images are presented as thumbnails on the right margin of the text; clicking on these thumbnails will expand the images to full resolution. Whole slide images are presented in-line with the text, and can be manipulated using the mouse in much the same fashion as [http://maps.google.com/ Google Maps] or [http://maps.bing.com/ Bing Maps]; use the scroll wheel to change the magnification level, and drag to move the field of view. On the top left, there is a toolbar. Magnification level can be adjusted using the + and - buttons on the toolbar. The rightmost button on the toolbar toggles fullscreen mode. On the top right corner of the whole slide image viewer, there is a thumbnail of the entire slide that the user may also use for navigational purposes. Finally, there is a navigational toolbox at the bottom of every page; from there, you can navigate to other chapters and chapter subheadings.
[[Histologic]] is optimized and tested for modern web browsers, including:

Older browsers may work, but are not explicitly supported.
