articular cartilage
covers epiphysis
Articular cartilage is a specialized type of connective tissue that covers the surface of joints within the body. Its main function is to provide a low-friction and shock-absorbing surface that allows for smooth movement of bones within a joint. It is comprised of chondrocytes (specialized cells that produce and maintain the extracellular matrix), collagen fibers, and proteoglycans.
Articular cartilage does not have a blood supply or nerves, so injury or damage to the tissue can be difficult to diagnose and treat. Overuse, trauma, and degenerative diseases such as osteoarthritis can all lead to damage or loss of articular cartilage. Treatment options vary depending on the extent of damage and may include physical therapy, joint injections, or surgery. It is important to note that once articular cartilage is lost, it cannot be fully regenerated by the body.
