Why is it called the axial skeleton?

These bones are divided into two main parts: Your appendicular skeleton and your axial skeleton. Your axial skeleton is made up of the bones along your vertical axis. Axial comes from the word “axis,” which means line. The bones line up along the central core of your body.
