The manubrium sterni or handle is the upper part of the sternum (sternum). With a quadrangular shape, wider on the upper side and narrower at the bottom, it has a joint joint with both the two bones and the first two ribs.
The upper edge of the manubrium, the incisura jugularis sternica, is well felt in the neck. At the front, the origins of the muscular pectoralis major and the muscular sternocleidomastoidus attach to the manubrium. At the back, this is the case for the muscular sternohyoideus and muscular sternothyreoidus.
