Breastbone

The breastbone, scientifically known as the sternum, is a flat bone located at the front center of the chest. It serves as a critical component of the ribcage, providing structural support and protection for vital organs like the heart and lungs. The sternum is divided into three primary sections: the manubrium, body, and xiphoid process. This bone also plays a key role in the attachment of ribs via costal cartilages.
