The common name for the scapula is shoulder blade.
The scapula, a flat and triangular bone located in the upper back, plays a crucial role in connecting the humerus (upper arm bone) with the clavicle (collarbone). Its primary function involves facilitating a wide range of upper body movements. Due to its location and shape, it's more popularly referred to as the shoulder blade. The term "scapula" itself originates from Latin, meaning "shoulder blade" or "shoulder bone," reflecting its anatomical position.
Key functions of the scapula include:
- Muscle Attachment: Serves as an anchor point for numerous muscles of the shoulder, back, and arm.
- Shoulder Movement: Enables diverse arm movements like rotation, elevation, and adduction.
- Protection: Provides some protection to the posterior aspect of the rib cage.
Therefore, while "scapula" is the anatomically correct term, "shoulder blade" is the everyday, commonly used term.
