Description
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.
There are two subcutaneous bursae located at the ankle joint, one at the lateral malleolus and one at the medial malleolus. They aid in reducing friction between the malleoli and the skin caused during movement.
