Light micrograph of hyaline cartilage, connective tissue, and ciliated epitehelium from the bronchus. 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.
