Document Summary

These are buried amongst the collagen fibrils. They are sulfated and therefore, hold water: glycoproteins and proteoglycans. These are found in the territorial matrix. The ec components of cartilage are essential to function: for example, upon damage, cells cannot start to re-synthesize type ii collagen. There are 3 main types of cartilage: hyaline. It is transparent or nearly transparent and usually homogenous. An example of this is articular cartilage, found at the end of bones: elastic, fibrocartilage. Hyaline cartilage: the chondrocytes in isogenous groups are round, the matrix is 90% collagen type ii, the non-fiber components include gags, proteoglycans, and glycoproteins. This is because cs is large mw and therefore, can bind more water: the collagen fibers are hard to distinguish from non-fiber components. There are 2 types of cartilage growth: Here, cells within the cartilage grow and divide. This leads to synthesis of new cartilage matrix: appositional growth.
