Description
The xiphoid process is the smallest, most variable sternal segment. It can range from rounded to bifid. At its junction with the body it forms shallow demifacets that complete the lower half of the last costal notch. It often remains cartilaginous late into life and can be perforated by a foramen.
Etymology
Xiphoid is a Greek word meaning sword-shape. It comes from the Greek words xiphos meaning a sword and eidos meaning form or shape. Process is a term used in anatomy to describe a projection on a bone. It comes from the Latin pro- meaning forward and cessus for gone. It is an old term that can be traced back to the writings of the early anatomist Celsus.
