Which bones make up the thoracic girdle in the human body?

The thoracic girdle, also known as the shoulder girdle, is primarily composed of the scapula (shoulder blade) and the clavicle (collarbone). This girdle plays a crucial role in connecting the upper limbs to the trunk and providing support and stability for shoulder movements. The scapula has a broad, flat shape that allows for a wide range of motion at the shoulder joint, while the clavicle acts as a strut that holds the scapula in place, ensuring proper alignment and mobility of the shoulder.

The importance of the thoracic girdle cannot be understated, as it serves as an attachment point for numerous muscles that facilitate arm and shoulder movements. Moreover, the design of these two bones allows for both strength and flexibility, enabling a variety of arm positions and movements essential for everyday activities and athletic performance.
