Which girdle anchors the lower limb?

Which girdle anchors the lower limb?

• A. Pectoral girdle
• B. Pelvic girdle
• C. Scapula
• D. Radius

Answer: (B)

Girdles are the rings of bones that attach the limbs to the axial skeleton and transfer forces between the trunk and the limbs. The pelvic girdle is the one that anchors the lower limb because it forms the ring of hip bones connected to the sacrum, supports body weight, and provides a stable hub (the acetabulum) for the femur at the hip joint. This setup enables the legs to bear weight and propel the body during movement. The pectoral girdle serves the upper limb and includes the scapula, while the radius is a forearm bone, not a girdle.
