So it's the highland cartilage that is found around our bones and around the joints. And this highland cartilage reduces the friction between bones. It also absorbs some of that shock as a result of the forces that we experience due to our daily movement. Now, the second type of cartilage is the elastic cartilage. And this cartilage contains a high proportion of elastin fibers, and that makes it very flexible. And so it's no surprise that elastic cartilage is a type of cartilage that is found in our outer ear.
