The sternoclavicular joint forms a direct connection between which bones?

• A. Sternum and clavicle
• B. Scapula and humerus
• C. Clavicle and scapula
• D. Sternum and scapula

Answer: (A)

The sternoclavicular joint is the direct articulation between the sternum (specifically the manubrium) and the clavicle. This is the only true bony link tying the upper limb to the axial skeleton, allowing movement of the clavicle as the shoulder girdle moves. The other options involve joints between the scapula and humerus (the shoulder joint), or between the clavicle and scapula (the acromioclavicular joint), or between the sternum and scapula (no direct bony joint). So the direct connection is sternum and clavicle.
