Sternum

This video tutorial provides a comprehensive overview of the sternum, a flat bone in the front of the rib cage. It covers the three main parts: the manubrium, sternal body, and xiphoid process, along with their unique features and articulations. The tutorial also highlights important bony landmarks and discusses the clinical significance of the sternum, including conditions like sternal foramen. The video concludes with a summary of the key points discussed.
