Question

The number of pairs of false ribs is

• A. 2
• B. 3
• C. 4
• D. 7

Answer 1

Answer: (B)

3

In humans there are normally 12 pairs of ribs. The first seven pairs are attached directly to the sternum by costal cartilages and are called true ribs. The 8${}^{th}$, 9${}^{th}$ and 10${}^{th}$ pairs are called as false ribs which do not join the sternum directly but are connected to the 7${}^{th}$ rib by cartilage. The 11${}^{th}$ and 12${}^{th}$ pairs are called floating ribs. So, there are 3 pairs of false ribs present. So, the correct answer is '3'.
