BREAST BONE Meaning and
Definition
-
The breast bone, also known as the sternum, is a flat, elongated, and V-shaped bone located at the center of the chest. It is positioned in front of the heart and lungs, connecting the ribcage and serving as a crucial structural component of the thoracic wall.
The breast bone serves several vital functions. Firstly, it acts as a shield, providing protection to the vital organs of the chest. Secondly, it plays a fundamental role in the respiratory system by anchoring the ribs and forming the front part of the thoracic cage. This allows the breast bone to expand and contract during breathing, aiding in the inhalation and expiration of air. Additionally, it acts as an attachment point for various muscles, ligaments, and tendons, contributing to the overall stability and mobility of the chest region.
The breast bone consists of three main parts: the manubrium, body, and xiphoid process. The manubrium is the superior portion of the sternum, connecting to the clavicles and the first pair of ribs. The body is the middle and largest section, articulating with the second to seventh pairs of ribs. The xiphoid process is the small, cartilaginous extension located at the bottom of the sternum.
Overall, the breast bone is a vital bone in the human body, responsible for providing protection, facilitating breathing, and supporting muscular attachments within the chest cavity.
