👉 Joint fluid, also known as synovial fluid, is a vital component of the joints that serves multiple essential functions. It acts as a lubricant, reducing friction between the articular cartilage surfaces during joint movement, allowing for smooth and pain-free motion. Additionally, it provides nutrients to the cartilage, which lacks its own blood supply, by transporting essential nutrients and removing waste products. Joint fluid also helps in shock absorption, cushioning the joint during impact activities and maintaining joint stability. Composed mainly of water, proteins, and hyaluronic acid, this fluid is produced by the synovial membrane lining the joint capsule and is continuously replenished to maintain its optimal viscosity and composition.
