Articular cartilage is the type of cartilage found at the ends of bones, particularly within joints. This specialized cartilage plays a critical role in reducing friction between the articulating surfaces of bones during movement. Its smooth, glassy appearance allows for easy gliding of bones against one another, which is essential for normal joint function and mobility.

Articular cartilage is a form of hyaline cartilage but is specifically located at the surfaces where bones meet in synovial joints. It has a unique structure that includes a high water content and a dense matrix of collagen fibers, which contributes to its ability to withstand compressive forces while also providing a low-friction surface for joint movement.

The other types of cartilage, such as fibrocartilage and elastic cartilage, serve different functions in the body. Fibrocartilage, found in structures like intervertebral discs and the pubic symphysis, provides tensile strength and absorbs shock, whereas elastic cartilage, which is more flexible, is found in structures such as the ear and the epiglottis. Understanding these distinctions highlights the unique role of articular cartilage in joint health and mobility.
