The document describes The Online Anatomical Human (OAH), a web-based anatomy education tool that links 2D and 3D anatomy. The OAH allows users to explore 3D pelvic models from segmented cryosection data in detail. It also enables annotation and quizzing functions. A MOOC on Coursera utilizing the OAH had over 7,000 participants worldwide. Ongoing evaluation includes large-scale user studies to assess user experience and performance. The goal is to provide open access to complex 3D anatomy models and knowledge traditionally limited to medical students.

• Current software:
• Accessibility?
• Idealized ‘average’ anatomy
• Lacking detail
• No link to 2D anatomy as
seen in medical imaging
• Dissections:
• Limited availability
• Real anatomy
• Interactive

10. How do we reach these students?
• We want to share the knowledge in the VSP with
medical students
• But how?
