The Parts that Make Up the Axial Skeleton and the Appendicular Skeleton

The skeleton is divided into two parts: Axial skeleton and the Appendicular skeleton

Axial skeleton- consists of 80 bones that form the vertical axis of the body.
The skull, mandible, sternum, ribs, vertebral column, and sacrum make up the axial skeleton .


Appendicular skeleton-
consists of 126 bones and includes the free appendages and their attachments to the axial skeleton.
skeleton clavicle, scapula, humerus, ulna, radius, carpals, metacarpals, phalanges, coxa, femur, patella, tibia, fibula, tarsals, and metatarsals make up the appendicular .
