When bones is not part of the pectoral girdle and attached limbs?

When bones are not part of the pectoral girdle and attached limbs, they may refer to those in the axial skeleton, such as the vertebrae, ribs, or skull. These bones serve different functions, primarily providing support and protection for vital organs, as well as facilitating movement and stability of the head and torso. Additionally, bones that are not part of the pectoral girdle can include those in the pelvic girdle and lower limbs, which are responsible for weight-bearing and locomotion.
