Vedclass · Answer

(A) In humans, the rib cage consists of $12$ pairs of ribs.These are classified based on their attachment to the sternum:$1$. True ribs: The first $7$ pairs are called true ribs because they are attached directly to the sternum via hyaline cartilage.$2$. False ribs: The $8th$, $9th$, and $10th$ pairs are called vertebrochondral (false) ribs as they do not attach directly to the sternum but join the $7th$ rib.$3$. Floating ribs: The last $2$ pairs ($11th$ and $12th$) are called floating ribs because their anterior ends are not attached to the sternum at all.Therefore, the number of true ribs is $7$ pairs.
