The hard bone plate in the middle of your chest is called the sternum. It is attached to ribs coming from your backbone, and to the clavicle bone (the long thin bone from your sternum to your shoulder).
The sternum is divided into three parts: Caput, corpus and processus xiphoideus.
The latter is the lowest part of the sternum, and consist of a small but pointy bony formation. You find it where the lower ribs from each site meet.
