Which anatomical structure connects the shoulder blade to the sternum?

The anatomical structure that connects the shoulder blade, or scapula, to the sternum is the clavicle. The clavicle is a long bone that acts as a strut, facilitating movement and stability of the shoulder joint. It spans from the sternum to the acromion of the scapula, effectively linking these two important parts of the upper body.

The clavicle plays a crucial role in maintaining the proper position of the scapula, which allows for a full range of motion in the shoulder. This connection is essential for various movements, such as raising the arm or lifting objects overhead. The sternoclavicular joint, where the clavicle meets the sternum, allows for movement and flexibility, further enhancing the functionality of the upper extremity.

In contrast, the scapula itself is the shoulder blade and does not directly connect to the sternum. The humerus is the bone of the upper arm and connects at the shoulder joint, but it does not connect to the sternum. The sternoclavicular joint, while it plays a role in the connection, is not the specific anatomical structure that links the shoulder blade to the sternum; rather, it is the joint formed by the meeting of the clavicle and the sternum.
