Human Skeleton Front
Human skeleton (front). Note the right forearm is pronated.

The human skeleton is the supportive and protective internal framework of the body that also serves as levers to allow locomotion.

The skeleton is composed of about 206 bones in adulthood, but this occurs after about 270 bones at birth become fused in maturity.

The human skeleton is divided into the axial skeleton and the appendicular skeleton.

Axial Skeleton

vertebral column,
the rib cage, and
other associated bones

Appendicular Skeleton
(attached to the axial skeleton)

the pelvic girdle,
the bones of the arms, and
the bones of the legs

Six Major Functions of Skeleton

Storage of minerals, and
Endocrine regulation
