Difference Between Axial and Appendicular
Axial and appendicular skeletons are the two main divisions of the human skeletal system. The axial skeleton includes bones from the central axis of the body, while the appendicular skeleton includes bones of the limbs and the girdles (shoulder and pelvic) that attach them to the axial skeleton.
The axial skeleton includes the skull, vertebral column, and ribcage. These bones protect the vital organs in the head and torso and provide support and structure for the body. The appendicular skeleton includes the bones of the arms, legs, hands, and feet. These bones are involved in movement and locomotion and also play a role in manipulating the environment.
