xiphoid process

Noun

xiphoid process (plural xiphoid processes)

1. The small cartilaginous extension to the lower part of the sternum, usually ossified in the adult human.
   • The adult sternum is comprised of three main parts—the manubrium, sternal body, and xiphoid process. The manubrium (fig. 7.2a) is the thickest, most superior part of the sternum, while the xiphoid process is variable in appearance and forms the inferior terminus of the sternum.2005, Brenda J. Baker, Tosha L. Dupras, Matthew W. Tocheri, The Osteology of Infants and Children, Texas A&M University Press, page 96
   • In chondrosternal prominence where there is angulation at the sternoxiphoidal junction, the xiphoid process is detached and a 2 to 3 cm length of the lower sternum is resected.2005, Kenneth L. Franco, Joe Billy Putnam, Advanced Therapy in Thoracic Surgery, 2nd edition, B.C. Decker Inc., page 152
