The ribs partially enclose and protect the chest cavity, where many vital organs (including the heart and the lungs) are located. Cartilage can be rigid and stiff or soft and flexible depending on its location in the body. It is only in the thoracic (midbody) region that the costal elements develop into ribs. On the thoracic wall, it occurs where the bone ends and cartilage begins. It helps in the formation of bones in growing children.

Any blunt-force trauma to the chest, shoulders, sides, or back can be transferred to the costal cartilage, resulting in tears, ruptures, or inflammation. In young children, the ends of the long bones of arms and legs are made up of cartilage which gradually change into bones and grow longer. The costal cartilage are segments of cartilage that connect the sternum to the ribs and help to extend the ribs into a forward motion. The main function of the sternochondral joint is to facilitate the mechanical ventilation by allowing the costal cartilage to glide with the ribs during inspiration and expiration. what is first costal cartilage? It includes cartilage, bones, ligaments, and tendons that connect bones and bones to muscles. The size of implanted cartilage could be decided in advance by referring to the results of LPG and NPS. .

The following structures consist of hyaline cartilage throughout life: Articular cartilage: the smooth, tough, wear-resistant articulating surfaces of bones in synovial joints. Cartilage is avascular and relies on diffusion, so the deposition of new cartilage is often very slow. To investigate this question, experimental indentation load-relaxation tests were perfor … Nutrients diffuse into the cartilage, but it is estimated that diffusion coefficients are in the order of 200 mm, a frac-tion of the diameter of costal cartilage.
