Cushioning

The cushioning function of synovial fluid is an integral aspect of its protective role in maintaining joint health. Synovial fluid's ability to absorb shock and impact safeguards the bones and joints from excessive forces and wear and tear.

During physical activities, such as walking, running, or jumping, the joints experience significant impact and stress. Without adequate cushioning, these forces could damage the bones and cartilage, leading to pain, inflammation, and potential long-term damage. Synovial fluid acts as a shock absorber, effectively dissipating and distributing these forces across the joint surface. This cushioning effect reduces stress on the bones and cartilage, protecting them from damage and promoting joint longevity.

Moreover, synovial fluid's cushioning properties contribute to the overall stability and functionality of the joints. By absorbing shock and impact, synovial fluid helps to maintain proper joint alignment and prevents excessive movement or instability.
