Which bone is the shoulder blade, its socket connects with the ball-shaped end of the humerus to provide arm movement?

Explanation:
The shoulder blade is the scapula, and its socket—the glenoid cavity—forms the ball-and-socket joint with the head of the humerus, allowing the arm to move in many directions. This setup is stabilized by surrounding muscles and tendons, making the shoulder one of the most mobile joints. The clavicle sits above it, connecting toward the sternum, but it isn’t the bone that forms the socket with the humerus. The radius and tibia are forearm and leg bones, respectively, and do not participate in this shoulder articulation.
