(kar’ti-lij)-a tissue characterized by its low blood supply, ability to maintain shape & small number of cells dispersed in a matrix of material produced by those cells. There are different types of cartilage that have different properties such as flexibility. Cartilage forms the central layer of the ear, the tip of the nose & the common wall between the nasal airways. This type allows the ear & nose to maintain their shape & yet remain flexible. A nonflexible cartilage covers the ends of bones on joint surfaces & allows smooth non-painful range of motion.
