After Borges · on exactitude in science
Borges wrote of cartographers who drew a map as large as the empire.1We're building that map for anatomy: every named structure, at full resolution, in one place, for the people who read bodies for a living.
1 On Exactitude in Science, 1946. The map covered the empire point for point, and was later left to rot in the desert. Ours is meant to be used.

This plate isn't a drawing. It's our own three-dimensional library, sliced in your browser, 28 cuts from the front of the head to the back. Every region you can see is a structure the atlas can name – hover one, or drag the ruler to move the cut.
Sections are computed from the model library (after Z-Anatomy, CC BY-SA 4.0), never traced by hand.

Every model traces back to an open anatomical source, and every structure carries its Foundational Model of Anatomy identifier, so a name means the same thing here as it does in the literature. Drawn at the scale of the thing it names.
The model library is licensed CC BY-SA 4.0, with attribution for every source.

Show a patient the exact structure you mean, not a textbook approximation.
Anchor findings to FMA identifiers so they line up across studies.
Learn anatomy as a navigable system, part by named part.
