synovial tendon sheath

(redirected from vaginal synovial membrane)

syn·o·vi·al ten·don sheath

a sheath of synovial membrane enveloping certain of the tendons; it contains a small amount of synovial fluid.

synovial tendon sheath

one of the many membranous channels or tubes enclosing various tendons that glide through fibrous and bony tunnels in the body, such as those under the flexor retinaculum of the wrist. One layer of the synovial sheath lines the tunnel, and the other covers the tendon. The sheath secretes synovial fluid, which lubricates the tendon. Compare synovial bursa, synovial membrane.

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

Synovial tendon sheath

Where the tendons cross joints, they are sheathed in thin membranes known as synovium, which provide lubrication to decrease friction.
