What are the three bones fused to create the sternum?

The three bones are the manubrium, the body of the sternum, and the xiphoid process. They fuse together to form the sternum, which is a flat bone located in the center of the chest.


Is the manubrium also called the breastbone?

The sternum consists of three portions: the manubrium (the upper segment of the sternum, a flattened, roughly triangular bone), the corpus or body of the sternum, and the xiphoid process (the little tail of the sternum than points down). These three portions of the sternum arise as separate bones and may fuse partially or completely with one another. Usually it's known as the sternum, but I suppose you could say manubrium as well.


What is the sternomanubrial junction region?

The sternomanubrial junction is where the manubrium (top part of the sternum) meets the body (sternum). It plays a role in connecting the sternum to the clavicles and first rib. It is an important landmark in the chest for medical examinations and procedures.
