Vedclass · Answer

(A) In the human rib cage, there are $12$ pairs of ribs.These are classified into three types based on their attachment to the sternum:$1$. True ribs ($1^{st}$ to $7^{th}$ pairs): These are directly attached to the sternum via hyaline cartilage.$2$. False ribs ($8^{th}$, $9^{th}$, and $10^{th}$ pairs): These do not attach directly to the sternum but join the $7^{th}$ rib.$3$. Floating ribs ($11^{th}$ and $12^{th}$ pairs): These are not connected to the sternum at all, hence they are called floating ribs.Therefore, there are $2$ pairs of floating ribs.

The number of floating ribs in humans is ............ . (in $pairs$)
