The Human Body

Author(s): Deanne Erdmann MS

Human Skeleton Diagram

The skeleton’s most important function is to provide support for the body. The skull, ribs, sternum and vertebral column make up the “upright,” rigid axial skeleton, while the arms, legs, shoulders and hips compose the more movable appendicular portion of the skeleton. The articulation of bones forms joints and provides the skeleton with flexibility, enabling it to be moved as muscles contract, extend and relax.
