Oct 26, 2023 · The sternum is the bone that lies in the anterior midline of our thorax. It forms part of the rib cage and the anterior-most part of the thorax. Its functions are to protect the thoracic organs from trauma and also form the bony attachment for various muscles.

The sternum (pl.: sternums or sterna) or breastbone is a long flat bone located in the central part of the chest. It connects to the ribs via cartilage and forms the front of the rib cage, thus helping to protect the heart, lungs, and major blood vessels from injury.

The body of sternum, considerably longer, narrower, and thinner than the manubrium, attains its greatest breadth close to the lower end. Surfaces. —Its anterior surface is nearly flat, directed upward and forward, and marked by three transverse ridges which cross the bone opposite the third, fourth, and fifth articular depressions.

The thorax consists of ribs, the sternum, and thoracic vertebrae. The sternum has three parts: The jugular notch (incisura jugularis) is located on the upper edge of the handle. The clavicular notch (incisura clavicularis) is located to the side (on each side) and is connected with the clavicle.

Sternum is the flat bone made by three parts (manubrium, corpus et processus xiphoideus) and synchodroses between them. Sternum stabilizes the ribs through their cartilages, limits the mobility of the thoracic spine, and, therefore, protects chest organs * .

The sternum has three main sections that you should know for anatomy exams: the manubrium, the body (gladiolus), and the xiphoid process. The letters MBX, just like the Honda motorcycle brand, can help you remember the order of the parts of the sternum (from top to bottom).

Explore the anatomy of the sternum body, its articulation, surfaces, and gender differences.

Sternum fractures are mostly located on the sternal corpus, seldom on the manubrium. Fractures of the sternal manubrium are, however, more frequently associated with severe concomitant injuries of thoracic organs, and therefore deserve special attention.
