Bones of the ventral trunk

This tutorial covers the anatomy of the ventral trunk, focusing on the sternum and its components. It explains the manubrium, its articulations with ribs and clavicles, and the sternoclavicular joint. The sternal angle and body are discussed, highlighting their clinical importance. The xiphoid process is also examined, including its role in rib articulation.
