What is the scapula commonly referred to as?

The scapula is commonly referred to as the shoulder bone. This bone is flat and triangular in shape, located in the upper back region. It connects the humerus (upper arm bone) with the clavicle (collarbone) and plays a crucial role in shoulder movement and stability. The scapula provides attachment points for several muscles that facilitate arm and shoulder movements, making it integral to the functionality of the shoulder joint.

The other terms listed refer to different bones: the pelvic bone refers to the bones forming the pelvis, while the upper arm bone refers specifically to the humerus. The leg bone is generally associated with either the femur, tibia, or fibula, depending on the specific context. Understanding these distinctions is important for recognizing the function and location of skeletal components in the body.
