Cartilage is a resilient and smooth elastic tissue, a rubber-like padding that covers and protects the ends of long bones at the joints, and is a structural component of the rib cage, the ear, the nose, the bronchial tubes, the intervertebral discs, and many other body components. It is not as hard and rigid as bone but is stiffer and less flexible than muscle.
The two primary functions of cartilage are:
Supporting Structures: Cartilage provides support to various tissues and structures. It maintains the shape and structure of soft tissues and organs. For instance, it forms the major portion of the external ear and nose, providing them with a firm yet flexible structure.
Facilitating Smooth Movements: Cartilage acts as a cushion between the joints, providing a smooth, lubricated surface for the bones to glide over without friction. This is crucial in joints like the knees and elbows to ensure smooth movement and reduce the risk of bones rubbing against each other and wearing down.
