<P> A bursa ( plural bursae or bursas ) is a small fluid - filled sac lined by synovial membrane with an inner capillary layer of viscous synovial fluid ( similar in consistency to that of a raw egg white ) . It provides a cushion between bones and tendons and / or muscles around a joint . This helps to reduce friction between the bones and allows free movement . Bursae are found around most major joints of the body . </P>
