Cranial nerve reference: Cranial Nerves and Foramina, University of Dundee, CAHID, CC BY 4.0. https://github.com/Z-Anatomy/Models-of-human-anatomy https://creativecommons.org/licenses/by-sa/4.0/ The named Z-Anatomy Bézier curves were sampled and triangulated without executing embedded scripts. The resulting adapted curve meshes are shared under CC BY-SA 4.0. They were registered to the BodyParts3D coordinate frame, lightly simplified and assigned instructional colors. The template's kidney and inner-ear models were not used. Shared BodyParts3D geometry is rendered only once, while searchable parent structures select their component meshes. Source curves and meshes may omit fine branches; the atlas does not cover every anatomical structure. Anatomy varies between people. Registration and simplification are for anatomy learning, not measurement or surgical navigation. The normal and disease viewers use the same source-derived thyroid mesh. Atlas refinement, 2026-09-07 -------------------------- Thyroid: Z-Anatomy, object "Thyroid gland", Gauthier Kervyn and contributors. CC BY-SA 4.0, including the adapted mesh and its schematic disease changes. Source revision: 3e343336567a817ec6bdd77132ecf9672570bde7. Adaptation: saved control vertices and faces, X mirror with seam welding, 3 mm shell thickness, two Catmull-Clark subdivisions, coordinate conversion. This offline adaptation follows the saved modifier settings; it is not a bit-exact Blender render. The source .blend SHA-256 is recorded on the mesh. Reproduction: scripts/refine-atlas.py (run after the baseline converters). Hepatic portal branches and celiac arterial branches, and normal arterial and venous meshes with BodyParts3D element IDs: source triangles are now retained without further decimation, to preserve thin vessels. Coordinates are converted and coincident vertices welded. Added left and right gastric veins: BodyParts3D 4.0 IS-A, FMA15399 / FMA15400, CC BY 4.0. The gastric vein itself is source geometry. The esophageal varices and small connecting collateral plexus are instructional schematic additions; they are not pathological meshes from the normal atlas. Normal anatomy muscles (normal-muscle.json) BodyParts3D 4.0 IS-A / PART-OF OBJ archive, CC BY 4.0. Source: https://dbarchive.biosciencedbc.jp/data/bodyparts3d/LATEST/ 56 paired named muscles. Source FMA and element identifiers are included per mesh. Changes: coordinate conversion, triangle reduction, combining muscle heads, colors. Copyright Database Center for Life Science (DBCLS), Japan. Disease story anatomy and projected lesson figures, 2026-09-07 ----------------------------------------------------------- story-anatomy.json reuses registered BodyParts3D 4.0 normal atlas meshes: paired adrenal glands, pituitary, aortic valve, hepatic veins, coronary arteries, pulmonary arteries and pulmonary veins. Original vertices and triangles are combined without further reduction. Source element IDs and normal source-model IDs are recorded per group. CC BY 4.0, DBCLS, Japan. Reproduction: scripts/build-story-anatomy.mjs. ../figures/*.svg are orthographic projections of the attributed normal meshes with computed face lighting and instructional color. These are source-derived projections, not patient images. Lower limbs and hands use the same body-surface triangle selection as the 3D viewer. Individual figures retain their source license: CC BY-SA 2.1 JP for STL adaptations, CC BY-SA 4.0 for Z-Anatomy's thyroid, and CC BY 4.0 for BodyParts3D 4.0. Source IDs and licenses are embedded in each SVG's metadata and listed in ../figures/manifest.json. Reproduction: scripts/build-lesson-figures.mjs. Clinical deformations in ../clinical-effects.js and ../disease-movie.js are schematic adaptations; applicable source share-alike terms continue to apply to adapted model data. Vegetation attachment refinement, 2026-09-08 ----------------------------------------- The independent schematic mitral vegetation is now centered on the nearest actual triangle of the attributed FMA7235 mitral mesh, rather than at a free-floating approximate coordinate. Source geometry remains unchanged. The attachment location is source-constrained; the pathological shape is still an instructional example, not a measured specimen. Complete adult skeleton, 2026-09-08 ---------------------------------- bone-inventory.json and bones-*.json.gz contain 206 standard adult bones plus two source entries for variable foot sesamoids outside that count. Individual model source identifiers and licenses are retained in each bundle. 199 standard bones and the additional foot sesamoids: BodyParts3D 4.0, IS-A OBJ99; coordinate conversion and vertex welding, no further decimation. The sternum combines the manubrium, body and xiphoid source components.
