What is the name given to the 11th and 12th pairs of ribs?

There are 12 pairs of ribs in the human body.Each rib is connected ventrally to the sternum.The first seven pairs of ribs are called true ribs.The 8th, 9th and 10th pairs of ribs are called vertebrochondral (false) ribs.The last 2 pairs (11th and 12th) of ribs are not connected ventrally and are therefore, called floating ribs.The Skeletal system is grouped into two main divisions - the axial skeleton which includes the bones that make up the central axis of the body such as the skull, spinal column, rib cage and the appendicular skeleton which includes bones of the upper and lower limbs and the bones that attach the limbs to the axial skeleton. Bones play a crucial role in supporting and providing structure to the human body. They also protect delicate organs, store minerals, and produce blood cells.
