As a result of the current COVID-19 pandemic, converting traditional face-to-face instructional methods into online courses have been a challenge. Online teaching offers limited options and means for explaining human anatomy, inflicting significant hardships in perceiving the depth and organization of anatomy among graduate students. This article addresses the integration of a 3-D anatomy application into an online graduate anatomy course among ninety-five Occupational Therapy scholars with various academic backgrounds enrolled via an online survey. Complete 3-D Anatomy app was used as a reinforcement to teaching human anatomy within the format of online Zoom sessions. Students' test scores and survey responses were employed to gather the information presented in this review. Results showed that all scholars believed the anatomy app was a useful supplement to the understanding of human anatomy, while the app-user pupils earned a greater percentage of passing grades in comparison to their peers in the non-app user group. Adopting the 3-D anatomy app as a supplemental tool during online anatomy courses to enhance students' understanding of human anatomy was successful. For prospective anatomy courses, we plan to integrate and explore the influences of an individual tablet/iPad with 3-D apps for each student for distinct insights on the impact of maneuvering and examining anatomical structures.
