Which bone forms the shoulder joint and connects to the scapula?

Explanation:
The shoulder joint is formed by the ball-and-socket connection between the head of the upper arm bone and the shallow socket in the shoulder blade (the glenoid). In this arrangement, the bone that actually forms the shoulder joint with the scapula is the humerus. The clavicle does connect to the scapula at the acromion, aiding stability and transferring forces, but it does not form the shoulder joint itself. The radius is a forearm bone and isn’t involved in the shoulder joint.
