Bewegungsflüssigkeit

Bewegungsflüssigkeit, also known as synovial fluid, is a viscous, egg-white-like substance found in the cavities of synovial joints. Its primary function is to lubricate the joint, reducing friction between the articular cartilages of the bones. This lubrication allows for smooth and effortless movement of the joints. Bewegungsflüssigkeit also acts as a shock absorber, distributing the forces exerted on the joint.

The fluid is produced by the synovial membrane, a specialized tissue lining the joint capsule. It is composed mainly of water, with dissolved proteins, lipids, and hyaluronic acid. Hyaluronic acid is a key component responsible for the fluid's viscosity and lubricating properties. Bewegungsflüssigkeit also contains phagocytic cells that help to remove waste products and debris from the joint space, contributing to joint health.

The amount and composition of Bewegungsflüssigkeit can change in response to joint health and activity. In healthy joints, the fluid is clear and straw-colored. Inflammation or disease within the joint can alter the fluid's appearance, making it cloudy or containing blood. Conditions like arthritis can lead to a decrease in the quality or quantity of Bewegungsflüssigkeit, resulting in pain and stiffness. Medical procedures such as arthrocentesis involve the removal and analysis of Bewegungsflüssigkeit to diagnose joint conditions.
