Floating ribs, also known as vertebral ribs, are the two lowest ribs on each side of the rib cage, and they do not attach directly to the sternum or cartilage of the sternum. True ribs (B) are the first seven pairs of ribs that attach directly to the sternum through costal cartilages. False ribs (C) are the next five pairs that do not attach directly to the sternum but rather attach to the costal cartilage of the rib above them. Cervical ribs (D) refer to any extra rib that develops above the first rib and can sometimes cause nerve and blood vessel compression. Thoracic ribs (E) are all the ribs that are attached to the thoracic vertebrae.
