Sternum
The sternum, commonly known as the breastbone, is a long, flat bone located in the center of the chest. Acting like a protective shield, the sternum safeguards the vital organs in your chest, such as the heart and lungs, by connecting to the rib cage. This bone works closely with the ribs and the collarbones (or clavicles) to form the front part of the rib cage.
In terms of its structure, the sternum is divided into three main sections: the manubrium at the top, the body in the middle, and the xiphoid process at the bottom. These sections play an essential role in supporting the rib cage, which houses and protects your chest's internal organs.
Understanding the sternum's role is crucial when considering its involvement in common procedures like CPR, where pressure is applied to the chest. Additionally, injuries to the sternum, such as fractures, often occur in accidents and require careful medical attention.
Overall, the sternum serves as a central part of our skeletal structure, offering protection and support to some of the body's most important functions.
