The human rib cage comprises 37 bones: Sternum (1, unpaired): It is also known as the breastbone and can be felt at the center of the chest. This bone articulates with the first 7 ribs. Thoracic vertebrae (12, unpaired): These are the 12 bones in the thoracic spine (T1-T12).

The rib cage or thoracic cage is an endoskeletal enclosure in the thorax of most vertebrates that comprises the ribs, vertebral column and sternum, which protect the vital organs of the thoracic cavity, such as the heart, lungs and great vessels and support the shoulder girdle to form the core part of the axial skeleton.

2025年1月27日 · The rib cage is a bony framework in the thoracic region that provides structural support and protection for vital organs such as the heart and lungs. It is composed of 12 pairs of ribs, the sternum (breastbone), and thoracic vertebrae.

2024年8月24日 · Discover the guide to rib cage anatomy, with parts, names & clear diagram. Learn how the rib cage protects vital organs & supports the body.

2025年2月13日 · There are twelve pairs of ribs that form the protective cage of the thorax. They are curved and flat bones. Anteriorly, they continue as cartilage, known as costal cartilage.

2017年8月1日 · The rib cage has three important functions: protection, support and respiration. It encloses and protects the heart and lungs. It provides a strong framework onto which the muscles of the shoulder girdle, chest, upper abdomen and back can attach. It is flexible and can expand and contract by the action of the muscles of respiration.
