Cartilage is bluish-white or gray and is semiopaque; it has no nerve or blood supply of its own. The cells lie in cavities called lacunae. They may be single or in groups of two, three, or four.

It also occurs in the costal cartilages of the ribs, in the nasal septum, in the external ear and lining of the eustachian tube, in the wall of the larynx, and in the trachea and bronchi. It forms the major portion of the embryonic skeleton, providing a model in which most bones develop.
