3D models

Interactive 3D anatomy uses Z-Anatomy (CC BY-SA 4.0) and BodyParts3D / Anatomography (CC BY-SA 2.1) — both free, open-source, downloadable, and built from real anatomical reference data.

What's not here: we deliberately avoid AI-generated medical illustrations. Image generators don't reliably know anatomy and can produce plausible-looking but clinically incorrect content — not acceptable for an educational tool that CRNAs and SRNAs rely on.
