Bursae are sac-like structures, with an inner synovial membrane, that produces a thin film of synovial fluid. They aid in reducing friction between moving tissues of the body, such as between tendon and bone, ligament and bone, tendons and ligaments, and between muscles.
Inflammation of the bursa is known as bursitis. If the inflammation is due to injury or strain, it is known as aseptic bursitis. However, if the inflammation is caused by infection, it is known as septic bursitis.
