This human anatomy ClipArt gallery offers 825 illustrations of the human skeletal system, including images of both the axial skeleton and the appendicular skeleton. The human axial skeleton includes 80 bones formed by the vertebral column (spine), the thoracic cage (e.g., ribs, sternum), and the skull. The axial skeleton is responsible for the upright position of the body. The human appendicular skeleton is composed of 126 bones formed by the pectoral girdles, the upper and lower limbs, and the pelvic girdle. These bones function in locomotion as well as protection of vital organs.
