synovial tendon sheath
A double-walled tubelike bursa that encloses a tendon. It consists of an inner visceral layer lying on and adhering to a tendon and an outer parietal layer; the two layers are separated by a space filled with synovial fluid. This sheath is found esp. in the hands and feet where tendons are confined to osteofibrous canals or pass over bony surfaces.Synonym: synovial sheath
