3D shoulder anatomy: origin and insertion on the bone

This Corpus3D image shows the shoulder girdle. The deltoid remains visible while surrounding muscles and bones fade. Origin bones turn light red and insertion bones light blue; the exact attachment areas become darker. This places the attachment areas in context with the scapula and upper arm.

In the interactive atlas you can rotate the shoulder, toggle muscle layers, and read each muscle’s origin, insertion, function, and innervation.
