The body of the sternum, also known as the gladiolus, is the longest part of the sternum, a flat bone located in the center of the chest. It connects to the ribs through cartilage, forming the front part of the rib cage. This structure plays a crucial role in protecting vital organs, such as the heart and lungs. The body of the sternum is typically about 15 centimeters long in adults and has a slightly curved shape. It serves as an attachment point for several muscles, including those involved in breathing and arm movement. The sternum is an essential component of the thoracic skeleton.
