Verified step by step guidance

Understand the classification of ribs in the human skeleton: Ribs are categorized into true ribs, false ribs, and floating ribs.

True ribs are the first seven pairs of ribs that are directly attached to the sternum via costal cartilages.

False ribs are the next three pairs (8th, 9th, and 10th) that are not directly attached to the sternum. Instead, they are connected to the 7th rib by cartilage.

Floating ribs are the last two pairs (11th and 12th) that do not attach to the sternum at all.

Count the pairs of false ribs: Since false ribs include the 8th, 9th, and 10th pairs, there are 3 pairs of false ribs in the human skeleton.
