Lower most two pairs of ribs (11th and 12th) are known as floating ribs because they are only attached to vertebrae but not to the sternum.
ANSWER:Yes they are. See the related link for more information on this.
Humans have 12 pairs of ribs - seven true and five false or floating rib pairs.
There are 12 pairs of ribs that make up the thoracic cage. The first 7 pairs are known as true ribs because they are directly connected to the sternum. The remaining 5 pairs are called false ribs, with some being floating ribs not connected to the sternum at all.
The rib cage is formed by the sternum (breastbone) in the front, the thoracic vertebrae in the back, and the ribs that connect them. There are 12 pairs of ribs, with the first seven pairs known as true ribs, the next three pairs as false ribs, and the last two pairs as floating ribs.

The lowest two pairs are known as floating ribs.
The rib pairs that attach to the back vertebrae but are not connected to the sternum are known as floating ribs. In human anatomy, the 11th and 12th rib pairs are termed floating ribs. There are 12 pairs of ribs. The floating ribs are the lowest two rib pairs that are also called false ribs.
ANSWER:Yes they are. See the related link for more information on this.
The ribs that don't connect to the sternum are known as floating ribs. There are two pairs of floating ribs, specifically the 11th and 12th pairs of ribs. Unlike true ribs, which attach directly to the sternum, and false ribs, which are indirectly connected, floating ribs are only attached to the vertebrae in the back and do not have any anterior connection. This anatomical feature provides flexibility and protection to the lower back.
Humans have 12 pairs of ribs - seven true and five false or floating rib pairs.
The two lowest pairs(making a total of four) are called floating ribs.
2 pairs
True ribs, because 7-pairs of costal cartilages join 7-pairs of ribs DIRECTLY to the sternum. False ribs, because the costal cartilage join 3-pairs of ribs to the seventh-rib not the sternum. Floating ribs, because the last 2-pairs of ribs neither connects to a costal cartilage and the sternum.
In humans, there are 12 pairs of ribs. The first seven pairs, known as "true ribs," articulate directly with the sternum via costal cartilages. The 8th to 10th pairs, called "false ribs," articulate indirectly through the costal cartilage of the rib above. The 11th and 12th pairs, known as "floating ribs," do not articulate with the sternum at all.
13 pairs which consists of 7 pair "true" ribs and 6 pair "false" ribs.
