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.

The bones of the top of the head are fastened together by what are called sutures which are locked together by little teeth of bone that shoot by each other, as shown in the figure. <em>b</em> is the suture at the top of the head between the two parietal bones; <em>a a</em> is that between the two parietal bones and the frontal bone in front; and <em>c c </em> is that between the parietal bones and the bone at the back part of the cranium. These bones are not completely formed in the newborn infant.
