The figure shows the direct connection between the bone of the 

 Manubrium stcrni and the cartilage of the first rib ; the articular cavity 

 between the cartilage of the second rib and the sternum is usually a 

 double one, formed by a continuation of the cartilage between the Manulriiun 

 and Corpus stcrni. The cavities of the other costo-sternal articulations are 

 single; they may be wanting entirely at the sixth and seventh costal 

 cartilage.
