What are the two divisions of the skeletal system?

The skeletal system is divided into two main components: the axial and appendicular skeletons. The axial skeleton includes the bones that form the central axis of the body, which consists of the skull, vertebral column, and rib cage. This part is crucial for protecting the brain and spinal cord, as well as supporting the body's structure.

On the other hand, the appendicular skeleton comprises the bones of the limbs and the girdles that connect them to the axial skeleton. This includes the shoulder girdle (clavicles and scapulae), the bones of the arms and hands, the pelvic girdle (hip bones), and the bones of the legs and feet. The appendicular skeleton plays a vital role in facilitating movement and locomotion.

The other options do not accurately represent the divisions of the skeletal system. Central and peripheral refer more to nervous system anatomy. Proximal and distal are terms used to describe locations on limbs relative to the trunk. Inferior and superior indicate directional terms rather than structural divisions of the skeleton. Understanding the distinction between axial and appendicular skeletons is fundamental in anatomy and provides insight into the body's structure and function.
