Appendicular Skeleton
Captions available
The idea
The appendicular skeleton comprises the limbs and the girdles that attach them to the axial skeleton, primarily supporting locomotion and manipulation rather than organ protection.
In practice
The pelvic girdle anchors the leg bones to the axial skeleton, transmitting weight from spine to ground.
Where people slip
A girdle bone belongs to the appendicular division even though it touches the axial skeleton directly.
