Explanation
Floating ribs are the last two pairs of ribs (eleventh and twelfth) in the human ribcage. They are called floating ribs because they do not attach to the sternum, but instead, they are attached to the vertebrae of the spine. Floating ribs are considered a part of the axial skeleton, which includes the bones of the skull, vertebral column, and ribcage.

About Support and Movement
Support and movement covers the axial and appendicular skeleton, bone structure, joints and the arrangement of skeletal muscles. Muscle contraction is explained through actin, myosin, sliding filaments, calcium ions and ATP, while arthritis is distinguished as a disorder of joints rather than a normal part of movement.
