The ribs are classified into three main types based on their attachment to the sternum.
Types of Ribs
According to their attachment to the sternum, ribs are classified as:
- True Ribs: Ribs that are directly attached to the sternum via their own costal cartilage.
- False Ribs: Ribs that are indirectly attached to the sternum via the costal cartilage of the ribs above them.
- Floating Ribs: Ribs that are not attached to the sternum at all.
