    Part 2: Histology of the Integumentary System

    1. Obtain the slides listed below that are available for today’s lab.
    2. Focus on each sample and identify the structures listed for each type of tissue.
    3. Indicate the total magnification you make each illustration at in the space provided.
    4. Illustrate each tissue you observe with the microscope at the magnification you listed.
    5. Label each illustration with the structures listed for each.
