Construction of the Equine Digestive System: A Tool for Teaching Topographical Anatomy.

Anatomy is traditionally regarded as a difficult, non-motivating course involving a large body of theoretical and practical content, and it is often associated with high levels of dropout and failure. Given the relevance of the topic, we propose an alternative active multisensory teaching tool consisting of the construction of a low-fidelity anatomical model assembled into an articulated equine skeleton. Model construction and assembly assists students in the recognition of the topography and anatomical boundaries of the equine abdominal digestive system. Digestive system organs (liver, pancreas, stomach, small and large intestines) were constructed using common, easily available materials, such as newspaper, balloons, laminated rubber sheets, and polyethylene cylinders. The method described in this study is a low-cost, user-friendly teaching tool that is potentially applicable across different academic disciplines and that can also be used to construct models of other systems and species. However, it should be combined with other anatomy teaching methods because it does not provide detailed representation of specific digestive system organ features.
