In humans linea alba runs from the xiphoid process to the pubic symphysis. Its origin is the xiphoid process of the sternum. Located at the inferior end of the sternum is the pointed xiphoid process. The inferior sternopericardial ligament attaches the pericardium to the posterior xiphoid process. The central xiphoid process at the rear of the breastbone is V-shaped. Ossification of the xiphoid process occurs around age 40. At the front, fibres insert into the xiphoid process and along the costal margin. The lower border is narrow, and articulates with the xiphoid process. Anatomically, the procedure is carried out under the xiphoid process, up and leftwards. The xiphoid process can be naturally bifurcated, and sometimes perforated. The "xiphoid process" is a translation of Latin "processus xiphoides". Its three regions are the manubrium, the body, and the xiphoid process. The pressure is not focused against the xiphoid process, to avoid breaking it. Both the Greek derived "xiphoid" and its Latin equivalent "ensiform" mean 'swordlike'.
