What is the common name for the scapula?

The scapula is commonly referred to as the shoulder blade because of its anatomical location and shape. The scapula is a flat, triangular bone located in the upper back, and it plays a crucial role in the shoulder joint and upper limb movement. It serves as an attachment point for several muscles responsible for arm and shoulder motion, making it integral to activities that involve lifting, pushing, or throwing. This term, "shoulder blade," is widely recognized in both medical and everyday language, allowing for easy communication and understanding when discussing the upper body structure. The other options refer to different bones: the forearm bone can refer to either the radius or ulna, the thigh bone is the femur, and the pelvis consists of multiple bones that form the lower part of the torso.
