The bones of the chest forma conical, bony cage. The bones thatform the chest are a portion of the spinalcolumn behind, the sternum or breastbone in front, and the ribs at the sternum is a flat bone, to which thecartilages of the ribs join in front. In ayoung person, the sternum is composedof three parts, but in later life these partsjoin firmly into one bone. THE OSSEOUS SYSTEM. is
