GENERAL HISTOLOGY

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 just a few collagen fibers embedded in its matrix. It is generally quite smooth, and has a bluish-white, glass-like appearance grossly. It is found in places like the rings that hold the trachea open and covering the articular (joint) surfaces of bones.

Detailed explanation-3: -Note the chondrocytes sitting in their lacunae. The matrix of hyaline cartilage contains fibres made up of Type II collagen.

Detailed explanation-4: -Hyaline cartilage contains type II collagen. All cartilage contains type II collagen; only fibrocartilage has both type I and type II collagen. Type I is found in organs, skin, tendons, and bones.

Detailed explanation-5: -Fibrocartilage contains large bundles of collagen fibres made up of Type I collagen. These bundles run linearly through the tissue separated by a cartilage matrix containing chondrocytes.
