A Closer Look at the Xiphoid Process
The xiphoid process, located at the lower end of the sternum, is a triangular bone structure. Although its size and shape may differ, it undergoes significant changes over time. The transformation of this bone is highly individualized and unpredictable. During the period of young adulthood until approximately the age of 40, it consists mainly of cartilage. However, as one reaches 60 years old, it becomes entirely calcified.
Muscles
The sternum is connected to various muscles in the body. One example is the pectoralis major, which is responsible for moving the head, neck, and arms. Additionally, some abdominal muscles also attach to the sternum. The xiphoid process, on the other hand, serves as an attachment point for the diaphragm. This muscle is vital for the process of breathing.
