Final answer:
The manubrium does not articulate with the xiphoid process. It connects with the first and second ribs, and the sternal end of the clavicle.
Step-by-step explanation:
The manubrium articulates with several bones, but it does not articulate with the xiphoid process. Specifically, the manubrium articulates with the first rib, the second rib, and the clavicle. The sternal end of the clavicle articulates with the manubrium at the sternoclavicular joint. The manubrium is the upper portion of the sternum, and the xiphoid process is the inferior tip of the sternum, which does not directly articulate with the manubrium as they are separated by the body of the sternum.
