THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -True ribs are those that have one to seven ribs and are connected to the sternum via their own costal cartilage. The ribs that connect the manubrium and sternum to the thoracic vertebrae are known as vertebrosternal ribs. Ribs 2 through 6 or 7 are included.

Detailed explanation-2: -Rib pairs 1-7 are considered true ribs because they attach to the sternum via their own separate costal cartilages. Rib pairs 8-12 are considered false ribs because they only attach to the sternum by attaching their combined costal cartilages with the costal cartilage of the 7th rib.

Detailed explanation-3: -Ribs 1–7 are classified as true ribs (vertebrosternal ribs). The costal cartilage from each of these ribs attaches directly to the sternum. Ribs 8–12 are called false ribs (vertebrochondral ribs). The costal cartilages from these ribs do not attach directly to the sternum.

Detailed explanation-4: -They are sometimes called vertebrosternal ribs. They differ from false and floating ribs because they directly articulate with the sternum by means of their costal cartilages.
