Question

How many ribs are called false ribs ?

• A. 10
• B. 4 pairs
• C. 12
• D. 3 pairs

Answer 1

The correct option is D 3 pairs

D. 3 pairs

Reason: In human, there are 12 pairs of ribs which form the bony lateral walls of the thoracic cage. The first seven pairs are called true ribs because their anterior ends are attached directly to the sternum by means of small pieces of hyaline cartilage, the costal cartilages. The eighth, ninth and tenth pairs of the ribs are called false ribs. They articulate by cartilage with costal cartilage of the seventh rib and thus are attached indirectly to the sternum.
