Detailed explanation-1: -Hyaline cartilage has abundant collagen fibers hidden by a rubbery matrix with a glassy (hyalin = glass), blue-white appearance. Functions: forms the supporting structures of the larynx (voice box), attaches ribs to the breastbone, covers the ends of many bones where they form joints.
Detailed explanation-2: -Hyaline cartilage has a pearly bluish-white tinge and under a low-power microscope the matrix appears amorphous and translucent (semitransparent) as in Figure 11.
Detailed explanation-3: -Several collagen subtypes have been identified in hyaline articular cartilage. The main and most abundant collagens are type II, IX and XI collagens.
Detailed explanation-4: -Hyaline cartilage consists of fine type II collagen fibers, chondrocytes (matrix producing cells), and the extracellular matrix (or ground substance). Type II collagen fibers are thinner than type I collagen fibers.
