The skeletal system is divided into two main parts: the axial skeleton and the appendicular skeleton.
The axial skeleton includes the bones of the skull, vertebral column, and rib cage. It serves various functions, including protecting the brain, spinal cord, and organs within the thorax, as well as providing a stable framework that supports the body’s posture.
On the other hand, the appendicular skeleton consists of the bones of the limbs and the girdles that attach them to the axial skeleton. This division enables movement and manipulation of the environment, as it includes the shoulder girdle, pelvis, and bones of the arms and legs.
In summary, the axial skeleton focuses on protection and stability, while the appendicular skeleton is crucial for mobility and interaction with the surroundings.
