ECM of articular cartilage. -collagen (Type II) that is dispersed throughout ground substance and produces strong tensile resistance to stress-Proteoglycans (aggrecans) that form strong, permeable fiber and attracts lots of water-water and dissolved electrolytes.one 1-superficial zone where fibers are parallel to surface Zone 2-middle zone where fibers are randomly oriented Zone 3-Deep zone of cartilage where fibers are vertically oriented.
Hyaline Cartilage. Hyaline cartilage is the most abundant cartilage type. In adults, it is found in the respiratory passageways, the nasal cartilages, costal cartilages and on the articular surfaces of bone.In embryos, it has a much wider distribution, forming the precursors (cartilage models) of the long bones.It is usually covered by a special layer of dense connective tissue, the perichondrium. Cartilage at articular surfaces of bones, having no perichondrium, is an exception and is identified as articular cartilage.n embryos, it has a much wider distribution, forming the precursors (cartilage models) of the long bones.
