Cartilage is a flexible connective tissue found in many areas of animal bodies including, the joints between bones, ends of the ribs, the ear, the nose, the bronchial tubes and the intervertebral disc in the spine. It is not as hard and rigid as bone, but it is stiffer and less flexible than muscle. The cartilage cushions your joint as you move and prevents bones from rubbing together.
