title: A human heart circulation teaching model using fiber-optic markers.
abstract: In teaching anatomy, models are invaluable for reviewing certain concepts, especially those requiring three-dimensionality. Marking points of reference most commonly with numbers, arrows, colored dots, or colored pins is essential for the successful use of these models. However, these marking approaches do not necessarily lend themselves to a "hands on" usefulness for students. Therefore, we have designed a model with fiber-optic reference points. Because of the fragility of models prepared from specimens, we used an acrylic case mounted on a wooden base to protect the human heart circulation model. With the aid of a simple penlight held to the wooden base, the fiber-optic strands illuminate for easy identification of key anatomical points. We use this model in conjunction with a printed self-instructional module.
