Verified step by step guidance

Step 1: Understand the axial skeleton. The axial skeleton consists of the bones that form the central axis of the body, including the skull, vertebrae, ribs, and sternum. It provides support and protection for the brain, spinal cord, and thoracic organs.

Step 2: Identify the components listed in the question. The options provided are vertebrae, sternum, femur, and ribs. Compare each option to the definition of the axial skeleton.

Step 3: Recognize that the vertebrae, sternum, and ribs are part of the axial skeleton. These bones contribute to the central framework of the body and are involved in protecting vital organs.

Step 4: Understand the femur's classification. The femur is a long bone located in the thigh and is part of the appendicular skeleton, which includes the limbs and girdles. It does not belong to the axial skeleton.

Step 5: Conclude that the femur is the correct answer because it is not part of the axial skeleton, unlike the vertebrae, sternum, and ribs.
