Light micrograph of a section through hyaline cartilage. Hyaline cartilage is a type of connective tissue that consists of an extracellular matrix (pink) produced by chondrocytes (purple), the only cells found in cartilage. Single chondrocytes reside in lacunae (holes). Hyaline cartilage coats joints, reducing friction between bones, as well as providing structural support to the nose and trachea (windpipe).
