The appendicular skeleton consists of the bones of the limbs and the girdles that anchor them to the body’s core. It includes the shoulder (pectoral) and hip (pelvic) girdles, as well as the bones of the arms, hands, legs, and feet. Together, these structures form the body’s framework for movement and interaction with the environment. Its main roles are to enable motion, provide support, and serve as attachment points for muscles, tendons, and ligaments. Closely connected to the axial skeleton, it works in coordination with the muscular and nervous systems to maintain balance, posture, and locomotion—making it vital for daily activities, athletic performance, and physical stability.
