The distinction between them is based on the amount of collagen and elastic fibers that are part of the intercellular matrix. It is composed of abundant bluish gray matrix embedded in which are lacunae. Lying within the lacunae are the cells that are involved in the synthesis of the cartilage, known as chondrocytes. Hyaline cartilage is found in the nose and tracheal rings. Elastic cartilage is found in the external ear, the walls of the auditory and the Eustachian canals, the epiglottis and the larynx.
Fibrocartilage is present at the insertion of ligaments and tendons into bone.
