Answer: 4. Articular cartilage- composed of elastic cartilage to allow flexibility. v
Explanation:
Articular cartilage is the smooth, white tissue that covers the ends of bones at a point where they come together to form joints. Healthy cartilage in our joints makes locomotion easier. It allows the bones to glide over each other with very little friction.
Articular cartilage is hyaline cartilage and is 2 to 4 mm thick. Unlike most tissues, articular cartilage lacks blood vessels, nerves, or lymphatics. It is made up of a dense extracellular matrix (ECM) with a sparse distribution of highly specialized cells called chondrocytes.
Articular cartilage is the highly specialized connective tissue of diarthrodial joints. Its main function is to provide a smooth, lubricated surface for articulation and to facilitate the transmission of loads with a low frictional coefficient. Articular cartilage doesn't of blood vessels, lymphatics, and nerves and is subject to a harsh biomechanical environment. Most important, articular cartilage has a limited capacity for intrinsic healing and repair. In this regard, the preservation and health of articular cartilage are very important to joint health.
