Rib cage

ribsribcagefirst rib
Much the way the first seven ribs articulate with the sternum, the cartilage in the celiac plexus joins on the xiphoid process, reinforcing it, and indirectly attaches the costal cartilage to the sternum.
A typical human rib cage consists of 24 ribs in 12 pairs, the sternum and xiphoid process, the costal cartilages, and the 12 thoracic vertebrae.

The xiphoid process, or xiphisternum or metasternum, is a small cartilaginous process (extension) of the lower (inferior) part of the sternum, which is usually ossified in the adult human.

Thoracic vertebrae

The xiphoid process is considered to be at the level of the 9th thoracic vertebra and the T7 dermatome.
The eighth thoracic vertebra is, together with the ninth thoracic vertebra, at the same level as the xiphisternum.

Pressure on the xiphoid process should be avoided when administering chest compressions in CPR, as this can cause the xiphoid process to break off, resulting in punctures or lacerations of the diaphragm.
At the front, fibres insert into the xiphoid process and along the costal margin.

Sternum

The xiphoid process, or xiphisternum or metasternum, is a small cartilaginous process (extension) of the lower (inferior) part of the sternum, which is usually ossified in the adult human.
Its three regions are the manubrium, the body, and the xiphoid process.

Pericardiocentesis

pericardium around the heart
Pericardiocentesis, the procedure whereby fluid is aspirated from the pericardium, often uses the xiphoid process as an anatomical landmark by which this procedure is carried out.
Anatomically, the procedure is carried out under the xiphoid process, up and leftwards.
