Light micrograph of hyaline cartilage and chondroblasts. Hyaline cartilage occurs in the nasal septum, trachea, the articular surfaces of joints, and sternal ends of ribs. It is a type of elastic connective tissue composed of specialized cells in a translucent, pearly-blue matrix. It is covered by a membranous perichondrium, except where it coats the ends of bones, and tends to calcify in advanced age.
