What is the function of synovial fluid in joints?

• A. To promote muscle growth
• B. To lubricate joints and provide cushioning
• C. To transmit nerve signals
• D. To absorb nutrients

Answer: (B)

Synovial fluid plays a crucial role in maintaining joint health and functionality. Its primary functions include lubrication, which allows for smooth movement of the joint surfaces against one another, reducing friction during physical activities. This lubrication is essential for preventing wear and tear on the cartilage that lines the joints. Additionally, synovial fluid provides cushioning, acting as a shock absorber during movements such as walking, running, and jumping. This cushioning effect helps to protect the bones and other structures within the joint from stress and injury. In contrast, the other options pertain to functions not associated with synovial fluid. Muscle growth is related to factors like exercise and nutrition, while nerve signal transmission involves different types of tissues, mostly nerve cells and their associated mechanisms. Absorbing nutrients is a function more aligned with processes in the digestive or circulatory systems rather than the role of synovial fluid in joint function. Thus, the ability of synovial fluid to lubricate and cushion joints is fundamental to maintaining joint mobility and overall musculoskeletal health.
