Sternum

The video tutorial provides a comprehensive overview of the sternum, detailing its three main sections: the manubrium sterni, corpus sterni, and xiphoid process. Each section's anatomical features and their connections to ribs and other bones are explored. The tutorial also covers the clinical significance of the sternum, including potential complications like the foramen sterni. The sternum's role in the rib cage and shoulder girdle is highlighted, emphasizing its importance in human anatomy.
