"shoulder blade" 的定义和意义

What is "shoulder blade"?

The shoulder blade, also known as the scapula, is a flat, triangular bone that plays a crucial role in the movement and stability of the shoulder joint. The shoulder blade connects the upper arm bone (humerus) to the collarbone (clavicle), forming the foundation of the shoulder girdle. It provides attachment points for various muscles involved in arm and shoulder movements, allowing for a wide range of motions, including lifting, pushing, and pulling. The shoulder blade's position and mobility contribute to the overall strength, stability, and functionality of the shoulder complex, enabling activities such as reaching, throwing, and carrying objects.
