Adding Rigor to Your Anatomy Course with Microscope Work

Updated: Sep 8

Histology is the study of the four major tissues within the human body: epithelial, connective, muscle, and nervous tissue. Histology is essential to understanding how the body functions and recognizing diseases. Despite its importance in the medical profession, many Anatomy and Physiology teachers are reluctant to include microscope work in their high school classrooms. Students and teachers alike are often eager to move on with the study of larger body systems rather than spending time on microscopic study of cells and tissues.

Histology, however, is essential to our understanding of gross anatomy. In fact, the structure of a specific body tissue can provide clues to its function within the body. This link between structure and function is known as the principle of complementarity. For example, goblet cells are a type of elongated epithelial cells that secrete mucus. Tissues that contain goblet cells are found in the respiratory system, reproductive system, and gastrointestinal tract. Students should be able to hypothesize that these tissues provide mucosal secretions due to the presence of these cells. In short, by weaving the principle of complementarity into the study of the human body, cellular biology becomes easier to understand.


Some teachers prefer to teach histology in the context of each body system. Personally, I like to begin with a short histology unit on the four tissues types and then provide more specifics as we proceed through the rest of the course. I also use a mixture of prepared microscope slides in class and virtual slides found online. If you are teaching students in a pre-med course, you may want them to have practice using a microscope. If you are teaching a more introductory course, you may want to use the virtual slides to save time. Students often need weeks of practice to master the use of a microscope, even if they’ve used one in a previous course.




If you’re planning to have students draw the slides, you may be interested in using the following guidelines. These will improve the results you will see from student microscope drawings.

  • Use pencil. Add color only when instructed to do so.

  • Title your drawing.

  • To label structures, use lines (not arrows) made with a ruler. Label lines should not cross each other.

  • Neatly print the labels at the end of the lines.

  • When making a drawing from a microscope, include magnification. When making a macroscopic drawing, provide a scale.

  • Fill as much of the space provided as possible.
