scapula
Explanation: 

Detailed explanation-1: -The inferior process of the sternum is the xiphoid process. It is joined with the body of the sternum by a symphysis that usually ossifies by 40 years of age. The xiphoid process also articulates with the costal cartilage of the seventh rib. The thoracic cage serves as an attachment site for a variety of structures.

Detailed explanation-2: -The xiphoid process is made up of 2 types of cartilage. It contains hyaline cartilage in the proximal portion and contains elastic cartilage in the distal portion.

Detailed explanation-3: -The xiphoid process can be broad, thin, monofid, bifid, trifid, curved, deflected, and contain foramina [1-3]. Current textbooks and human anatomy atlases depict the xiphoid process as a single, straight, fully ossified bone on the inferior aspect of the sternum corpus.

Detailed explanation-4: -The xiphoid process is the smallest region of the sternum, or breastbone. It’s made up of cartilage at birth but develops into bone in adulthood. It’s located where the lower ribs attach to the breastbone. The tip of the xiphoid process resembles a sword.
