One, the sternum.
Thorax is enclosed by breast bones, ribs and thoracic vertebrae.
The clavicles and ribs are lateral to the sternum. Both bones articulate with the breastbone.
Same as an adult, 12 (on each side). The top 6 pair join in front at the sternum (breastbone), the lower 6 are connected only in back.
The lower bones of the breastbone are called the xiphoid process. It is the smallest and most inferior part of the sternum, which is located at the base of the breastbone. The xiphoid process is typically made of cartilage in early life but can ossify into bone with age. It serves as an important attachment point for various muscles and ligaments.
The breastbone or sternum protect the heart. The ribs also help protect the organs in the chest including the lungs.
Pain in the chest wall around the breastbone (or sternum) is the most characteristic feature of the condition known as costochondritis.
The sternum, also known as the breastbone, is a flat bone typically consisting of three parts. These parts are the manubrium, body, and xiphoid process. So, in total, the sternum consists of three bones fused together.
In the human body, there are three bones that typically exist as a single structure: the sternum (breastbone), the hyoid bone (located in the neck), and the sacrum (a fused bone at the base of the spine). These bones play crucial roles in providing structure and support but are unique in that individuals generally have only one of each.
The breastbone, also known as the sternum, is located in the center of the chest. It connects to the rib bones and helps protect the heart and lungs.
Your breastbone is called the sternum.
The breastbone is anteromedial to the shoulder blade.
The sternoclavicular joint is formed by the articulation between the clavicle (collarbone) and the manubrium of the sternum (breastbone), along with the first costal cartilage.
