What are the two other names for the breast bone of chickens?

The breast bone of chickens is commonly referred to as the sternum or keel. This is significant because the sternum is the central bone in the chest that supports the rib cage, providing structure and protection to the internal organs. The term "keel" is particularly used in avian anatomy and refers to the ridge on the sternum, which is more pronounced in birds that are adapted for flight. This keel allows for the attachment of powerful flight muscles, making it a critical element of a bird’s anatomy. The use of these terms is essential for understanding the skeletal structure of poultry, especially in a showmanship context, where knowledge of the anatomy can influence judging criteria or care practices.
