In a patient with rheumatoid arthritis, the synovial fluid in the temporomandibular joint (TMJ) typically exhibits decreased viscosity. Rheumatoid arthritis is characterized by chronic inflammation of the synovial membrane, leading to an influx of inflammatory cells and exudates. This inflammation results in the production of synovial fluid that is less viscous due to the breakdown of hyaluronic acid and the presence of inflammatory mediators.

Reduced viscosity of the synovial fluid can contribute to increased joint friction and may result in pain and reduced mobility in the TMJ. This altered fluid environment can exacerbate the symptoms experienced by individuals with rheumatoid arthritis. The condition can also lead to changes in the joint structure and function over time, affecting the overall mechanics of the TMJ.

In contrast, the other choices do not accurately describe the typical changes observed in the synovial fluid of a patient with rheumatoid arthritis.
