Upper portion of the sternum is called what?

Explanation:
The upper portion of the sternum is the manubrium. The sternum has three parts: the manubrium at the top, the body in the middle, and the xiphoid process at the bottom. The manubrium forms the upper border of the thoracic cage and provides articulation points with the clavicles and the first ribs. The clavicles connect to the sternum at the clavicular notches on the manubrium, not to the other parts. The xiphoid process is the small tip at the bottom, and the body is the central portion. The suprasternal (jugular) notch sits on the top edge of the manubrium, helping you locate it.
