Which of the following bones belongs to the axial skeleton?
Correct answer: C. Sternum
- A. Femur
- B. Clavicle
- C. Sternum
- D. Scapula
Explanation
The axial skeleton is the central supporting column: skull, vertebral column, ribs and sternum. The clavicle and scapula are tempting because they lie in the trunk, but they form the pectoral girdle, which attaches the arms and so belongs to the appendicular skeleton along with the femur and all other limb bones.
