The sternum is commonly referred to as the breastbone. It is a flat, elongated bone located at the center of the chest and serves as a vital part of the rib cage, providing attachment points for ribs and protecting essential organs like the heart and lungs. The term "breastbone" accurately reflects its position on the anterior aspect of the thorax, making it a recognizable name in both anatomical and layman's terms. Recognizing the relationship between the sternum and its function in chest structure helps in understanding its role in both anatomy and medical emergencies.
