Detailed explanation-1: -Ten of the twelve ribs connect to strips of hyaline cartilage on the anterior side of the body. The cartilage strips are called costal cartilage (“costal” is the anatomical adjective that refers to the rib) and connect on their other end to the sternum.
Detailed explanation-2: -The costal cartilages are bars of hyaline cartilage which serve to prolong the ribs forward and contribute very materially to the elasticity of the walls of the thorax.
Detailed explanation-3: -There are 12 pairs of ribs in the body. They are attached to the vertebral column with most of the ribs anteriorly joining to the sternum bone via costal cartilage. The first seven ribs directly attach to the sternum (true ribs), whereas the following three ribs only attach to the costal cartilage of the true ribs.
