Xiphisternal joint
The xiphisternal joint (or xiphisternal symphysis) is a location near the bottom of the sternum, where the body of the sternum and the xiphoid process meet. It is structurally classified as a synchondrosis, and functionally classified as a synarthrosis.[citation needed] The joint usually ossifies by the fourth decade of life,[1] forming a synostosis.[citation needed] It is in line with[clarification needed] the T9 vertebra.[citation needed] References
