Bones of the skull, vertebral column, and rib cage belong to which skeleton?

Explanation:
The central-axis bones—the skull, vertebral column, and rib cage—form the axial skeleton. This part of the skeleton supports the body’s main axis andProtects vital organs: the brain and spinal cord in the skull and spine, and the heart and lungs in the rib cage. In contrast, the appendicular skeleton includes the limbs and their girdles. Terms like compact bone and medullary cavity refer to bone tissue and internal structures, not to a major skeletal division, so they aren’t appropriate names for a skeleton group.
