The bones in the upper arm, its ball-shaped and connects into the socket of the scapula are called the?

Explanation:
The main idea here is naming the bone that forms the upper arm and how it connects to the shoulder. The upper arm bone is the humerus. Its proximal end features a rounded head that fits into the glenoid cavity of the scapula, creating the ball-and-socket shoulder joint. This structure enables a wide range of motion at the shoulder. The other bones listed aren’t part of the upper arm: the radius and ulna are forearm bones extending from the elbow to the wrist, and the clavicle is the collarbone that sits on top of the shoulder but doesn’t form the arm’s main bone.
