In human beings a total of 12 ribs are present.
- Each rib is a thin flat bone, which is connected to the vertebral column and also to the sternum.
- The ribs are also connected dorsally to the thoracic vertebrae and attached ventrally to the sternum with the aid of a hyaline cartilage.
- The rib cage is formed together with the Thoracic vertebrae, ribs, and the sternum. Thus ribs are attached to the sternum, making 12 pairs of ribs among human beings.
