Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many false ribs are there?
A
2
B
3
C
7
D
None of the above
Explanation: 

Detailed explanation-1: -Because the last three pairs of ribs, the 8th, 9th, and 10th pairs, do not directly articulate with the sternum, they are referred to as false ribs.

Detailed explanation-2: -Ribs eight to ten are the false ribs and are connected to the sternum indirectly via the cartilage of the rib above them. The final two pairs of ribs are floating ribs and the cartilage of these ribs tends to end within the abdominal musculature. These three types can then be classified as either typical or atypical.

Detailed explanation-3: -Ribs 1–7 are classified as true ribs (vertebrosternal ribs). The costal cartilage from each of these ribs attaches directly to the sternum. Ribs 8–12 are called false ribs (vertebrochondral ribs). The costal cartilages from these ribs do not attach directly to the sternum.
