The scapula is a large, flat, triangular bone that forms the posterior part of the shoulder girdle and serves as an attachment site for 17 different muscles. It glides along the posterior chest wall, enabling a wide range of arm movements. The scapula's unique shape features several processes and fossae that enhance its role as a mobile foundation for upper limb function.
The term comes from Latin "scapula" meaning shoulder blade, which itself likely derives from ancient Greek "skaptein" meaning "to dig," perhaps referring to its shovel-like shape.
