In this item, we are identifying two labeled joints on the diagram.
Option 1: 'sternoclavicular joint'. This is the joint between the clavicle (collarbone) and the sternum (breastbone). On the diagram, label #1 is placed at the joint where the medial end of the clavicle meets the manubrium of the sternum, which corresponds exactly to the sternoclavicular joint.
Option 2: 'acromioclavicular'. This is the joint between the acromion of the scapula and the acromial end of the clavicle. On the diagram, label #2 sits at the joint near the outer top of the shoulder where the clavicle meets the acromion, which is the acromioclavicular joint.
To verify accuracy, recall the distinct anatomical landmarks: the sternoclavicular joint is at the medial clavicle-sternum junction (near the center of the chest), whereas the acromioclavicular joint is at the lateral aspect of the shoulder where the clavicle meets the acromion of the scapula. The placements in the image align with these definitions, reinforcing that #1 corresponds to the sternoclavicular joint and #2 corresponds to the acromioclavicular joint.
