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 upper two vertebrae of the spinal column, involved in head movement. In performing the rotary motion of turning your head, the skull does not move alone, but it moves together with the first vertebra. The first vertebra in this motion moves on the second around a tooth-like process that stands up from this second vertebra. This tooth works in a smooth notch on the inside of the first vertebra. It is bound very fast in this notch by a strong ligament, so that it may not, in any of the quick motions of the head, be made to press on the delicate spinal marrow which lies against it.

The vomer is a single bone, situated vertically at the back part of the nasal fossae, forming part of the septum of the nose. It is thin, somewhat like a ploughshare in form; but varies in different individuals, being frequently bent to one of the other side; it presents for examination two surfaces and four borders.
