The question "What are false ribs class 6?" appears to be incomplete or slightly misphrased. A more accurate question, based on anatomical context, would be: "Which ribs are classified as false ribs?". Considering this, the answer is provided below.
False ribs do not directly connect to the sternum. According to the reference provided, they are the eighth, ninth, and tenth pairs of rib bones. These ribs are also known as vertebrochondral ribs.
Understanding False Ribs
False ribs differ from true ribs in their attachment to the sternum.
- True Ribs (1-7): These ribs connect directly to the sternum via their own costal cartilage.
- False Ribs (8-10): These ribs connect to the sternum indirectly. Their costal cartilage joins with the cartilage of the seventh rib before connecting to the sternum.
- Floating Ribs (11-12): These ribs have no connection to the sternum at all.
Characteristics of False Ribs
False ribs are crucial for the structure and flexibility of the rib cage.

| Pairs | Eighth, ninth, and tenth rib pairs. |
