What bones make up the shoulder joint?

The shoulder joint is primarily composed of three bones: the clavicle, scapula, and humerus. The clavicle, commonly known as the collarbone, connects the arm to the body and plays a crucial role in stabilizing the shoulder. The scapula, or shoulder blade, provides an attachment point for various muscles that facilitate shoulder movement. The humerus is the upper arm bone that fits into the glenoid cavity of the scapula, forming the ball-and-socket configuration that allows for a wide range of motion in the shoulder.

This combination of bones is essential for the proper functioning of the shoulder, allowing for movements such as lifting, reaching, and throwing. Each of these bones contributes to the structure and stability of the shoulder joint, which is one of the most mobile joints in the human body. The other options presented in the question include bones that do not participate in forming the shoulder joint or involve incorrect combinations of bones. Thus, the correct selection highlights the appropriate anatomical components involved in shoulder articulation.
