The axial skeleton consists of the following bones, Skull, facial bones, hyoid bone, rib cage, and the vertebral column.
How are limbs and girdles part of the axial skeleton?
The bones of the appendicular skeleton (the limbs and girdles) “append” to the axial skeleton. 1. Skull Bones Protect the Brain and Form an Entrance to the Body.
