sternum bone anatomy
The sternum, commonly known as the breastbone, is a flat bone that forms the front portion of the rib cage in humans. It consists of three main parts: the manubrium, the body, and the xiphoid process. The sternum plays a critical role in the protection of vital organs, such as the heart and lungs, by acting as a shield. It also provides an attachment point for the ribs, allowing for the expansion and contraction of the chest during breathing. Technologically, the sternum is a marvel of natural engineering, providing structural integrity to the thoracic cavity. In medical applications, understanding sternum bone anatomy is crucial for surgeries, orthopedics, and trauma care.
