Which term refers to the group of bones attaching the upper limb to the axial skeleton?

• A. Pelvic Girdle
• B. Pectoral Girdle
• C. Upper Limb
• D. Myel/o

Answer: (B)

The group of bones that connects the upper limb to the axial skeleton is the pectoral girdle, also known as the shoulder girdle. It consists of the clavicles (collarbones) and the scapulae (shoulder blades), and it anchors the arm to the trunk while allowing a wide range of motion. The pelvic girdle serves a similar connecting role for the lower limbs, attaching them to the axial skeleton through the hip bones. The upper limb itself is the arm and hand, not the connecting structure, and myel/o is a combining form meaning bone marrow or spinal cord, not a girdle.
