What is the purpose of the synovial membrane?

The synovial membrane plays a crucial role in joint function by producing synovial fluid, which is essential for lubricating the joint cavity. This lubrication significantly reduces friction between the articular cartilage of the bones during movement, allowing for smoother and more efficient motion. By minimizing friction, the synovial membrane helps to prevent wear and tear on the cartilage and protects the joint structures from damage.

Additionally, the synovial fluid created by the membrane also serves to nourish the cartilage, as cartilage lacks its own blood supply. The function of reducing friction is fundamental to maintaining joint health and mobility, making the purpose of the synovial membrane critical for proper joint mechanics during physical activity.
