Description: The xiphoid process is a small cartilaginous projection located at the lower part of the sternum, which is part of the bony structure of the thorax. This appendage, also known as the xiphoid appendix or xiphoid process, has a triangular shape and serves as the attachment point for several important muscles and ligaments in the body. Although predominantly cartilaginous in childhood, it can ossify and become a more solid bone in adulthood. Its primary function is to serve as an anchor point for the muscles of the abdomen and diaphragm, thus contributing to the stability and mobility of the thorax. Additionally, the xiphoid process is an important anatomical landmark in medical procedures, such as cardiopulmonary resuscitation (CPR), where it is used as a guide for the correct placement of chest compressions. Its location and characteristics make it a key element in human anatomy, although it is often overlooked compared to other components of the skeletal system.
