Notes

Sternum or breastbone is a long, flat bone located in the center of the thorax (chest). It connects to the rib bones via cartilage, forming the rib cage with them, and thus helps to protect the lungs and heart from physical trauma.

The sternum is usually cut open (a sternotomy) to gain access to the thoracic contents when performing cardiothoracic surgery.
