Which set correctly describes the appendicular skeleton?

• A. Pelvis and limbs
• B. Skull and vertebral column
• C. Ribs
• D. Vertebral column only

Answer: (A)

The appendicular skeleton includes the bones of the limbs and the girdles that attach them to the trunk. That means the pelvis (hip girdle) together with the limbs (arms and legs) are part of this system. The pelvis provides the attachment point for the legs and supports locomotion, while the limb bones themselves enable movement and manipulation of our environment. In contrast, the skull, vertebral column, and ribs belong to the axial skeleton, which forms the central axis of the body and protects vital organs. So describing the pelvis and limbs captures the components that make up the appendicular skeleton.
