<P> Where the underlying subintima is loose, the intima sits on a pliable membrane, giving rise to the term synovial membrane . </P> <P> This membrane, together with the cells of the intima, provides something like an inner tube, sealing the synovial fluid from the surrounding tissue (effectively stopping the joints from being squeezed dry when subject to impact, such as running). </P> <P> Just beneath the intima, most synovium has a dense net of fenestrated small blood vessels that provide nutrients not only for synovium but also for the avascular cartilage . </P> <P> In any one position, much of the cartilage is close enough to get nutrition directly from the synovium . </P>

Where is the synovial membrane found and what is its role
