Abstract
The skeletal system is a fundamental framework that supports and protects the body, consisting of two primary divisions: the axial and appendicular skeletons. The axial skeleton includes the skull, vertebral column, and rib cage, forming the central axis of the body and providing protection for vital organs such as the brain, spinal cord, and heart. The appendicular skeleton comprises the limbs and girdles, enabling movement and interaction with the environment. Bones within these divisions are categorized into types such as long, short, flat, and irregular bones, each with distinct structural characteristics suited to their functions. The axial skeleton’s bones, such as the vertebrae and ribs, are designed to protect and support the body’s central structures, while the appendicular skeleton’s bones, like the femur and humerus, facilitate movement and leverage. Together, these bones perform critical roles in locomotion, support, protection, and mineral storage, highlighting their importance in maintaining overall body function and structure.
