limited by the position of the clavicle joint at the sternoclavicular joint
Bones that are involved are the sternum and the ribs.
the joints which allow abduction of the shoulder are the glenohumeral joint which is formed between the humerus and the glenoid fossa, the sternoclavicular joint which is formed between the upper portion of the sternum and the clavicle and also the acromioclavicular joint which is formed between the acromion process and the clavicle all of these joints work together with the muscles which produce shoulder abduction to create this movement.
The point at which the clavicle and the scapula connect is a joint called the acromioclavicular joint.The acromioclavicular joint.

limited by the position of the clavicle joint at the sternoclavicular joint
The medial end of the clavicle forms the sternoclavicular joint. The lateral end of the clavicle forms the acromioclavicular joint.
"The clavicle articulates with the sternum to form the sternoclavicular joint, the only direct connection between the upper extremity and the trunk. The sternoclavicular joint is extremely weak because of its bony arrangement, but it is held securely by the sternoclavicular ligament that pull the clavicle downward and twoards the sternum, thus anchoring it.
Bones that are involved are the sternum and the ribs.
The sternoclavicular joint is a joint which does not move. This is the area of cartilage which joins the clavicle (or collar bone) to the sternum (or breast bone).
There is the sternoclavicular-joint and the carpalmetacarpal-joint of the thumb. So in total: 4
Gleno-humeral joint (scapula to humerus) Claviculo-acromial joint (clavicle to acromion of scapula) Sternoclavicular joint (attaches clavicle to sternum) Scapula articulates with the back of the chest so bones humerus (in the arm), clavicle sternum and scapula
There are actually only two. The glenohumeral (or scapulohumeral) which is the joint between the humerus and the glenoid cavity of the scapula, and the acromioclavicular, which is the joint between the clavicle and the acromion of the scapula. I guess you could also include the sternoclavicular, which is the joint between the sternum and the clavicle, but that is not technically part of the shoulder girdle.

The lateral third has two surfaces, an upper and a lower; and two borders, an anterior and a posterior.
