Adductor pollicis: oblique head FJ1481 / FMA46121 (right), FJ1481M / FMA46122 (left);
transverse head FJ1515 / FMA46123 (right), FJ1515M / FMA46124 (left).
Only the respective side is loaded in unilateral studies. These are two heads of
one muscle, not two muscles. Original source vertices and faces are preserved.
70 unique right-sided meshes assembled from the shoulder/arm, elbow, forearm
and hand subsets. Shared IDs appear exactly once. Includes 32 bones (the
clavicle and scapula plus the 30 principal free upper-limb bones) and 38
selected muscle meshes (including the two interosseous groups). This is not a complete soft-tissue reconstruction.

Changes: OBJ to JSON conversion, smooth normals and illustrative colors.
Original source positions and topology are preserved exactly. No invented,
repositioned, cropped or deformed anatomy. See provenance.json for FMA/source
mappings, original OBJ hashes and output checksum.
Accessory/sesamoid bones, many muscles, cartilage, ligaments, nerves, vessels
and skin are omitted. No joint animation or clinical validation is claimed.

Legacy OBJ headers may mention CC BY-SA 2.1 Japan; the current archive license

Lumbricals added as one complete source group per hand: FJ1510 (FMA42398),
FJ1510M (FMA42399) where the respective side is loaded. Individual muscles
within each group are not separate selectable objects. No geometry altered.
