The sternum, commonly known as the breastbone, is a flat bone that forms the front of the ribcage. It plays a crucial role in protecting the vital organs located in the chest, such as the heart and lungs. The sternum is connected to the first seven ribs and provides structural support to the chest cavity.
Structure of the Sternum
The sternum is typically divided into three parts: the manubrium, body, and xiphoid process. The manubrium is the broadest and most superior portion of the sternum, connecting to the clavicle and the first rib. The body of the sternum, also known as the gladiolus, is the longest part and articulates with the second to seventh ribs. The xiphoid process is a small piece of cartilage at the inferior end of the sternum.
Functions of the Sternum
The sternum serves several essential functions in the human body. It protects the delicate organs in the chest, including the heart and lungs, from external trauma. Additionally, the sternum provides attachment points for various muscles that help with breathing and arm movements. It also assists in the production of red blood cells as it contains red bone marrow.
Common Conditions
Several conditions can affect the sternum, including fractures, infections, and abnormalities. A sternum fracture usually occurs as a result of trauma, such as a car accident or a direct blow to the chest. Sternum infections, though rare, can be caused by bacteria entering the bloodstream or following surgery. An abnormality like pectus excavatum, also known as funnel chest, causes an inward depression of the sternum.
Overall, the sternum is a vital component of the skeletal system, providing protection and support to the chest cavity while facilitating essential bodily functions such as breathing and arm movement.
