Skeletal System


The human skeletal system is divided into two main groups: the axial skeleton and the appendicular skeleton. The axial skeleton includes bones associated with the body's main axis, the spine. This includes the spine and the skull and rib cage, which are connected to the spine. The appendicular skeleton is attached to the axial skeleton and consists of the bones associated with the body's appendages—the arms and legs. This includes the bones of the pectoral girdle, or shoulder area, bones of the pelvic girdle, or hip area, and arm and leg bones.
