[00:00:00]The sternum is a flat midline bone of the anterior thorax composed of the manubrium, body, and xiphoid process that articulates with the clavicles and costal cartilages of the ribs.

[00:00:12]It functions to protect vital mediastinal structures including the heart and great vessels while serving as an important attachment site for the ribs, pectoral muscles, and other thoracic structures.

[00:00:24]Common pathology involving the sternum includes sternal fractures, costochondral injuries, osteomyelitis, and congenital deformities such as pectus excavatum and pectus carinatum.
