Answer
- Floating ribs- 2 pairs
Explanation:
Ribs that articulate directly with the sternum are called true ribs, whereas those that connect indirectly via cartilage are termed false ribs. The floating rib refers to the two lowermost, the eleventh and twelfth rib pairs. They are so called because they are attached only to the vertebrae and not to the sternum or cartilage of the sternum.
