Which group of bones attaches the lower limbs to the axial skeleton?

• A. Pelvic Girdle
• B. Pectoral Girdle
• C. Upper Limb
• D. Syndrome

Answer: (A)

The connection point for the lower limbs to the spine is the pelvic girdle. This girdle is made of the two hip bones that meet the sacrum at the sacroiliac joints, forming a ring that anchors the legs to the axial skeleton and transfers body weight from the spine to the legs during standing and movement. The pelvic girdle is specifically designed to support and stabilize the pelvis and hips, enabling efficient locomotion.

The other options don’t serve this role: the pectoral girdle (clavicles and scapulae) attaches the upper limbs to the axial skeleton, not the lower limbs. The upper limb refers to the arm region itself, not a girdle. And “syndrome” isn’t a bone group at all.
