• Many samples are of human origin and come from autopsy or surgical procedures. In all cases, permission was given by the patient or family to use the tissue for teaching purposes.
• In this exercise, we will first look at the method of glass slide preparation so that you will have the understanding of where the scanned slides came from.
• This unit will also include a short segment on use of the optical as well as virtual microscope.

Objectives for this laboratory:

• Describe the histological techniques used in preparing samples for light and electron microscopy.
• Explain the mechanism of biological staining (acidophilia and basophilia) and the way in which common stains are used to provide information about cells in light microscopy.
• Interpret images of cells, tissues, and organs when seen with both the light and electron microscopes.
   

Have you ever wondered where the tissues come from and how the slides are made?
