Muscleβbone attachment β the first hurdle for the moving body
π¦Ώ Muscle↔bone attachment
Without an attachment, a muscle that contracts pulls on nothing. This is the first hurdle for the moving body.
π΄ THE BODY CANNOT BE ATTACHED YET β 16.0% of the muscles have a sourced attachment
Measured again just now by the source tool β nothing is cached.

β οΈ The 3D model on screen has no separate muscles: glb/muscle.glb holds
only one unnamed mesh (geometry_0), 0 skin, 0 animation β the muscles were
melted into one piece at export. Yet they still exist in the source _sources/muscle.fbx
(named objects, left and right). The body has not lost its muscles: it has lost their separation.

A bone is not just something named a bone: in the FMA, it is a class that descends from βBone organβ. Animation rig (skins): yes.
β οΈ 202 is a minimum, not a round number: three entries below (sacrum, body of sternum, zone of sternum) are bones to an anatomist, but the FMA files them elsewhere. We prefer a proven count that can be debated to a round count that cannot be checked.
body of sternumβ the FMA classifies it as: Zone of sternum
intervertebral disk of cervical vertebraβ the FMA classifies it as: Intervertebral disk
zone of sternumβ the FMA classifies it as: Zone of bone organ
sacrumβ the FMA classifies it as: Subdivision of vertebral column
left first costal cartilageβ the FMA classifies it as: First costal cartilage
left second costal cartilageβ the FMA classifies it as: Second costal cartilage
left third costal cartilageβ the FMA classifies it as: Third costal cartilage
left fourth costal cartilageβ the FMA classifies it as: Fourth costal cartilage
left fifth costal cartilageβ the FMA classifies it as: Fifth costal cartilage

Law β β the attachment comes from the FMA, a reference
database of human anatomy (has_origin Β· has_insertion Β· attaches_to Β·
receives_attachment_from), never from parts simply being close in 3D. A muscle with no
FMA relation is a declared gap, not a guess. Tool:
