The skull is one of the major components of the axial skeleton. Name the other two. Then explain what structures do each of these component areas protect.
a) The other two components are the vertebral column and the rib cage. The vertebral column protects the spinal cord, while the rib cage protects the heart and lungs.
b) The other two components are the pelvic girdle and the clavicle. The pelvic girdle protects the reproductive organs, while the clavicle protects the shoulder joint.
c) The other two components are the humerus and the femur. The humerus protects the upper arm muscles, while the femur protects the thigh muscles.
d) The other two components are the ulna and the radius. The ulna protects the elbow joint, while the radius protects the wrist joint.
