kõõlmevedeliku

Kõõlmevedelik, also known as synovial fluid, is a viscous lubricating fluid found within the articular capsule of synovial joints. It is a clear to yellowish, slightly sticky substance primarily composed of hyaluronic acid, lubricin, and various proteins, including enzymes. This fluid acts as a shock absorber, reducing friction between the cartilage surfaces of bones as they move against each other.

The synovial membrane, a specialized tissue lining the joint capsule, is responsible for secreting kõõlmevedelik. This secretion process is a continuous one, with the fluid being recycled and reabsorbed by the membrane. The composition and volume of kõõlmevedelik can be affected by various factors, including age, joint health, and physical activity.

In healthy joints, kõõlmevedelik plays a crucial role in maintaining joint mobility and preventing wear and tear on the cartilage. Conditions such as arthritis can lead to changes in the quality or quantity of kõõlmevedelik, resulting in pain, stiffness, and reduced joint function. Medical professionals may analyze kõõlmevedelik through a procedure called arthrocentesis to diagnose joint conditions. The fluid's properties, such as its viscosity and cellular content, can provide valuable diagnostic information.
