The physiology behind the transmission of a nerve signal within the neuromuscular junction (NMJ) is a complex concept that can be used as a framework to explain many other signal transduction events across physiology. These can include neurotransmitter release, membrane depolarization, and channel activity. Traditionally, complex and static drawings have been used to teach this mechanism of action to students. While useful, these images can become complicated due to the lack of physically moving parts. A simple video could be sufficient but we wanted to create a unique and memorable moving diagram that combines a static image with moving images. After developing, building, and programming the model, we used it in two different introduction to physiology classes; one aimed at pre‐professional students and one aimed at students entering non‐patient care‐related fields in the health sciences. To determine whether the model was successful, we asked students about their understanding of the material before and after exposure to the board and their interaction with the board. While there was no significant impact on their exam scores compared to classmates who did not use the model, students were generally appreciative of the model. Students noted that the model helped them to visualize the process, allowing them to learn step by step and at their own pace, however, they also suggested that the sequence of lights is slowed down and that the model be more available prior to the exam.
