Inferiormost part of the sternum

Answer 1

The three parts are called

* Manubrium (top-most part)

Answer 2

The inferiormost part of the sternum is known as the xiphoid process. It is a small, cartilaginous extension at the bottom of the sternum and does not fully ossify until adulthood. The xiphoid process serves as an attachment point for some abdominal muscles and provides support to the lower part of the ribcage.

Answer 3

The "spur" at the end of the sternum, assuming that's what you're talking about, is called the xiphoid process.
