Types of Cartilage and Ossification of Bones

The three types of cartilage argon hyalin cartilage, fibrocartilage, and elastic cartilage. clear cartilage is the weakest form of cartilage and entirelyows flexibility. It reduces friction by promote 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 tack on the surfaces of most joints such as the ends of long bones. Fibrocartilage differs from hyaloid cartilage because it lacks perichondrium. It is the strongest form of cartilage. This type of cartilage is both exacting and strong. Fibrocartilage is found in the intervertebral discs and the pubic symphysis. Elastic cartilage, alike hyalin cartilage, contains perichondrium. This type of cartilage is both elastic and strong. It keeps the function of some structures in place. Elastic cartilage is found i n 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. epiphyseal growth plates cause long bones grow longer.

During adolescence hyaline cartilage stays between the diaphysis and epiphysis. Young chondrocytes be constantly dividing within the epiphyseal plate. New chondrocytes are created on the epiphyseal side of the plate when the bone lengthens, but the heaviness stays a constant size. On the other hand, antique chondrocytes are replaced by bone on the diaphyseal side, cause the length of the bone to increase. When adulthoo d is reached between the ages of 18 and 25 g! rowth 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 full(a) essay, tell apart it on our website: BestEssayCheap.com
