Liigvedelik

Liigvedelik, also known as synovial fluid, is a viscous, colorless fluid found in the cavities of synovial joints. It acts as a lubricant, reducing friction between the articular cartilages of bones during movement. This fluid also provides nourishment to the cartilage, which lacks its own blood supply.

The composition of liigvedelik is primarily water, along with proteins, hyaluronic acid, and lipids. Hyaluronic acid, a glycosaminoglycan, is responsible for the fluid's high viscosity. The cells lining the joint capsule, called synoviocytes, produce and secrete liigvedelik.

In a healthy joint, the volume of liigvedelik is relatively small, but it plays a crucial role in maintaining joint health and function. Conditions affecting the joints, such as arthritis, can lead to changes in the quantity and quality of liigvedelik. For instance, in osteoarthritis, the cartilage wears down, and the liigvedelik may become less viscous and contain inflammatory substances.

Diagnostic procedures sometimes involve analyzing a sample of liigvedelik, obtained through a process called arthrocentesis. This analysis can help identify infections, inflammatory conditions, or crystal deposition diseases within the joint. The properties of liigvedelik are essential for smooth, pain-free joint movement throughout life.
