What is the number of 'True Ribs' in human body?
Correct answer: B. 14
- A. 12
- B. 14
- C. 16
- D. 18
Explanation
Humans have 12 pairs of ribs, and the first seven pairs attach directly to the sternum; these are called true ribs. Therefore, 7 pairs x 2 ribs per pair = 14 true ribs. Students may choose 12 by counting pairs as individual ribs or may choose 18 by confusing true ribs with the total number of ribs.
