Cartilage is one of the most interesting tissues within the body. In almost all places within the body, cartilage is found with no nerves and no blood vessels within the tissue. In fact, the cartilage of intervertebral discs is the largest structure within the body without direct blood supply!
Cartilage provides a smooth, friction-free surface for smooth gliding of joints. The composition of cartilage is largely water and tough connective tissue. When damaged by trauma or chronic conditions such as arthritis, the smooth gliding of joints is disrupted and can become painful and difficult.
