👉 Juvenile fluid, also known as synovial fluid, is a viscous, clear liquid found within the cavities of joints in growing animals, including humans. It plays a crucial role in reducing friction between the articular cartilage surfaces during joint movement, thereby facilitating smooth and pain-free motion. Produced by the synovial membrane lining the joint cavities, juvenile fluid also helps in nutrient distribution to the cartilage and removes metabolic waste products. Its composition includes water, proteins, hyaluronic acid, and various electrolytes, all of which contribute to its lubricating and nourishing properties. This fluid is particularly abundant in synovial joints during early development but gradually decreases as the animal matures, reflecting the changing needs of joint function over time.
