Which is part of the appendicular skeleton?

Explanation:
The appendicular skeleton includes the bones of the limbs and the girdles that attach them to the body's central axis. The scapula, or shoulder blade, is part of the pectoral (shoulder) girdle that connects the upper limb to the trunk, enabling a wide range of shoulder movements and providing attachment points for muscles. It articulates with the clavicle and the humerus, placing it squarely in the appendicular skeleton. Vertebrae, skull, and ribs belong to the axial skeleton—the bones that form the skull, spine, and rib cage along the central axis—so they are not part of the appendicular group.
