Types of Cartilage and Ossification of Bones

The three types of gristle argon hyalin cartilage, fibrocartilage, and elastic cartilage. hyalin cartilage is the weakest form of cartilage and entirelyows flexibility. It reduces friction by boost the joints. Hyaline cartilage includes a buoyant gel as it ground substance and has very fine collagen fibers. Almost every of this type of cartilage is surrounded by perichondrium except in places where the bones lengthen when growth occurs. Hyaline cartilage is pose on the surfaces of most joints such as the ends of long bones. Fibrocartilage differs from hyaline cartilage because it lacks perichondrium. It is the strongest form of cartilage. This type of cartilage is both hard-and-fast and strong. Fibrocartilage is found in the intervertebral discs and the pubic symphysis. Elastic cartilage, alike hyaline cartilage, contains perichondrium. This type of cartilage is both elastic and strong. It keeps the liaison of some structures in place. Elastic cartilage is found in part of the external ear and as the lid on top of the larynx. 2. Endochondral ossification is when bone replaces cartilage in the body. epiphysial growth plates cause long bones grow longer. During adolescence hyaline cartilage stays between the diaphysis and epiphysis. Young chondrocytes are constantly dividing within the epiphyseal plate. New chondrocytes are created on the epiphyseal side of the plate when the bone lengthens, but the onerousness stays a constant size. On the other hand, venerable chondrocytes are replaced by bone on the diaphyseal side, causing the length of the bone to increase. When adulthood is reached between the ages of 18 and 25 growth of new cells and matrix stop. This is the point where all cartilage is replaced by bone, length of bone stops growing, and now on that point is an epiphyseal line.If you want to get a expert essay, tell apart it on our website: BestEssayCheap.com
