describe the structure of hyaline cartilage |
|
Answer» Hyaline cartilage contains a lot of collagen; it contains type II, specifically. Type I is found in bones, organs, skin, and tendons, and most of the collagen in the human body is type I. However, cartilage is composed of type II. Hyaline cartilage also contains themoleculechondroitin sulfate, which helps it to resist being compressed. However, it is the weakest of the three types of cartilage because its collagen fibers are very fine. Hyaline cartilage is very uniform in appearance. It is surrounded by a membrane called the perichondrium, which provides nutrients to the cartilage since the cartilage tissue has no blood vessels of its own. The dark spots are chondrocytes, while the light-colored circles surrounding them are the lacunae. In microscope images, the collagen in hyaline cartilage is not visible because it is so fine. The other types of cartilage, elastic and fibrocartilage, have visible collagen when viewed under a microscope. |
