Analyze skeletal system divisions

The skeletal system is divided into two major parts: the axial skeleton and the appendicular skeleton. This relates to how the body groups structures, building on the concept of Levels of Organization.

• The axial skeleton forms the central axis of the body and includes the skull, vertebral column, and thoracic cage.
• The appendicular skeleton consists of the limbs and the girdles (pectoral and pelvic) that anchor the limbs to the axial skeleton.
