Analyze the skeletal divisions

Using the Skeletal System and Skeletal Anatomy knowledge points, we recall that the human skeleton is divided into two main parts: the axial skeleton and the appendicular skeleton.

Identify the components of each division

• 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 that attach them to the axial skeleton. Specifically, it contains the pectoral (shoulder) girdle and the pelvic (hip) girdle, along with the upper and lower extremities.

Match with the given options

The question asks which structure contains the pectoral girdle and the pelvic girdle. This matches the definition of the appendicular skeleton.
