How is the skeleton divided?

The division of the skeleton into axial and appendicular components provides a clear way to understand the structure and function of the bones in the human body. The axial skeleton consists of the bones that form the long axis of the body, which includes the skull, vertebral column, and rib cage. This section supports and protects vital organs such as the brain, heart, and lungs and provides a framework for the body's overall structure.

On the other hand, the appendicular skeleton includes the bones of the limbs as well as the bones that anchor the limbs to the axial skeleton, such as the shoulder girdle and pelvis. This division plays a crucial role in facilitating movement and mobility, as the appendicular skeleton is primarily responsible for the limbs' ability to perform various activities.

Understanding this division helps in areas such as anatomy, kinesiology, and physical therapy, as it highlights how different parts of the skeletal system interact with muscles and joints to enable movement, maintain stability, and protect vital organs.
