xiphoid

Now I’ve got him pinned with my knee on his xiphoid, making it hard for him to breathe, much less move.

“Just to the bottom of the xiphoid process,” Ms. Boyle said.

Actually, the “lump” is the xiphoid process, the quarter-size cartilaginous end of the bony sternum.

Two little girls were united from the xiphoid cartilage to the umbilicus.

The posterior extremity of the sternum, flattened from above downwards, ends in a cartilaginous plate; concave superiorly, and convex inferiorly: this is the abdominal prolongation, or xiphoid appendix.
