This page describes where the content of Ana3D comes from and how far it has been checked. The short version: the models and English names come from published scientific sources; translations and guides are produced with machine assistance, and no anatomist has reviewed them yet; this page is where that is stated.
Names of structures
English names come from the Foundational Model of Anatomy (FMA), UBERON and the source atlases. Latin names follow Terminologia Anatomica (TA2) where the source provides them.
Names in the other ten languages are partly taken from Terminologia Anatomica tables and Wikidata, and for the most part written by a language model that was given the Latin name and the English name as anchors. No anatomist has reviewed these translations yet. They certainly contain errors. Every page in these languages is therefore:
- excluded from search engines (
noindex) until its language has been reviewed.
Definitions
Definitions come from UBERON (licensed CC BY 3.0) and Wikidata (CC0). The source and the licence are printed under each definition. A definition in a language other than English is a machine translation of the English text.
Text from Wikipedia is never copied; a structure page may link to the Wikipedia article.
Relations between structures
Origin, insertion, innervation, blood supply and drainage are taken from Wikidata statements. Where a relation is missing on a page, the data source does not state it; that does not mean the relation does not exist.
Guides
The guides in the Learn section are drafted with a language model. The model is given the names, parts and relations of the structures from the atlas and is instructed to write standard textbook anatomy only: no statistics, no literature citations, no clinical advice.
A draft is not a reviewed text: the guides are drafted with AI assistance and no anatomist has reviewed them yet. Once a named reviewer has checked a guide, the page names the reviewer. Guides are kept as plain files so that a reviewer can correct them directly, and a corrected file is never overwritten by a new draft.
3D models
Every model is shown under the licence of its source, with the credit line of the atlas printed under the model and baked into exported images. Where we changed the data (conversion to a web format, simplification, a mirrored brain in one source) the credit line or the atlas notes say so. Known defects of the source data are listed rather than hidden.
The twelve CT cases come from a public, anonymised research data set. No skin or face surface is built from them.
What we do not publish
- Advice on diagnosis or treatment.
- Data whose licence forbids commercial use, forbids derivatives, or could not be verified.
- Models extracted from commercial anatomy software.
Not a medical device
Ana3D is a study tool. It is not a medical device and must not be used to make clinical decisions.
