Definition - What does Synovium mean?

The synovium is a soft tissue that lines joints, tendon sheaths, and bursae.The synovium forms a protective membrane around the joint space and also produces lubricating substances to smooth the motion of the joints. the synovium is susceptible to inflammation and injury from repetitive motion. This joint lining is also called the synovial membrane.

SureHire explains Synovium

Synovium tissue is comprised of very thin layers of cells that serve to lubricate and protect the spaces between joints, and inside tendon and joint sheaths. The synovium tissue forms a membrane that encloses the space around joints and controls the passage of fluids in and out of those spaces.

Bursae that form cushions between points of friction in the musculoskeletal system, such as between the tendons and bones of the shoulder or knee, are lined with synovial membrane.

Synovium cells are non-adherent and thus do not attach to the joints and tendons they surround. This characteristic, in addition to the lubricating fluid produced by the synovium, facilitates the smooth motion of the joints and tendons.

Inflammation of the synovium results in a condition known as synovitis that can cause pain and swelling of the joints.
