Appendicular Skeleton

The appendicular skeleton is composed of 126 bones in the human body. The word appendicular is the adjective of the noun appendage, which itself means a part that is joined to something larger. Functionally it is involved in locomotion (Lower limbs) of the axial skeleton and manipulation of objects in the environment (Upper limbs). The appendicular skeleton forms during development from cartilage, by the process of endochondral ossification.
