By forming sternoclavicular joint & Acromioclavicular joint, clavicle connects sternum (Axial skeleton) to scapula (Appendicular skeleton). Clavicle transmits the weight / force of appendicular skeleton to axial skeleton. acromioclavicular ligament is impoant in this. That's why clavicle is most commonly fractured bone in body -Sternum contains - Manubrium - Body - Xiphoid process * Manubrium of sternum: angled posteriorly on body of sternum at manubriosternal joint, forms sternal angle which is major surface landmark used by clinicians in physical examination. * RIBS: All ribs aiculate with thoracic veebrae posteriorly, most ribs (II to IX) have 3 aiculations with veebral column. anteriorly, costal cailages of ribs I to VII aiculate with sternum, VIII to X aiculate with inferior margins of costal cailage above them, XI & XII floating ribs - because they do not aiculate with ribs, costal cailage or sternum
