Key points

- True ribs attach to the sternum through their own costal cartilages, while false ribs lack this direct attachment.
- A typical rib has a head, neck, tubercle, angle and shaft, with a costal groove along its lower inner border.
- Ribs protect the chest contents, provide muscle attachments and move during breathing.
