Drawing as a pedagogical tool in anatomy has been shown to be effective at increasing knowledge and engaging students. Therefore, a three-dimensional drawing activity of the dural venous sinuses was implemented to increase knowledge of the structures and improve understanding of their spatial orientation and drainage. Students were given a pre-test, listened to a lecture, performed the activity, and completed a post-test. For this activity, students working in pairs were given markers and white swim caps and instructed to draw the sinuses on their partner’s swim cap with anatomical accuracy. Results from the post- test revealed a significant increase in knowledge related to the structure and drainage of the dural venous sinuses. Students found that drawing was an effective way to learn anatomical structures and strongly agreed that translating a two-dimensional picture into a three-dimensional drawing improved their understanding of anatomical orientation. Overall, this was a quick, effective activity utilizing three-dimensional drawing to solidify the understanding of the dural venous sinuses. https:// doi.org/10.21692/haps.2019.027
