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 Os Innominatum, or nameless bone, so called from bearing no resemblance to any known object, is a large irregular shaped bone, which, with its fellow of opposite side, forms the sides and front wall of the pelvic cavity. Labels: R, O, crest of ilium, just below O is seen the anterior superior spinous process; J, tuberosity of ischium; t, part of pubes, between J and T is seen the thyroid foramen: H, acetabulum, below H is seen end of ubic bone which, with its fellow of opposite side, forms the symphysis pubis.

Male pelvis (top) and female pelvis (bottom). The pelvis is stronger and more massively constructed than either the cranial or thoracic cavity. It is composed of 4 bones, the ossa innominata, forming sides and front, and the sacrum and coccyx, completing it behind. The female pelvis differs from that of the male in making it better adapted for giving birth. The most notable differences are that the female pelvis is wider in every direction, giving more room for the child to pass and shallower, which lessens the distance through which the child has to be propelled; and lastly, the bones are thinner and smoother.
