Explanation:
Detailed explanation-1: -The true ribs articulate with the sternum by the sternocostal joints. The first rib is an exception to that rule; it is a synarthrosis. Another thing that is good to know is that the first rib could uniquely articulate with the clavicle by the costoclavicular joint.
