The fluid between the joints is called synovial fluid, also known as joint fluid. This thick, egg-white-like liquid acts as a lubricant, reducing friction between the bones during movement and providing cushioning to protect the ends of bones. Normally, only a small amount is present.
Understanding Synovial Fluid
Synovial fluid's primary role is to minimize friction within synovial joints. This allows for smooth, efficient movement. The fluid's properties are vital for joint health and functionality. Several sources confirm this:
- MedlinePlus: States that synovial fluid is a thick liquid located between joints, and its analysis is a common medical test. https://medlineplus.gov/lab-tests/synovial-fluid-analysis/
- Verywell Health: Describes synovial fluid's lubricating and friction-reducing properties. https://www.verywellhealth.com/how-to-increase-synovial-fluid-5114374
- Wikipedia: Highlights the fluid's egg-white consistency and its crucial role in reducing friction between articular cartilage. https://en.wikipedia.org/wiki/Synovial_fluid
- Cleveland Clinic: Mentions that bursae, fluid-filled sacs, act as protective cushions between bones, ligaments, and other joint parts. While not directly synovial fluid, they contribute to joint cushioning. https://my.clevelandclinic.org/health/symptoms/21908-joint-effusion
- University of Rochester Medical Center: Also mentions bursae, alongside synovial fluid, as contributors to joint cushioning. https://www.urmc.rochester.edu/encyclopedia/content.aspx?contenttypeid=85&contentid=P00044
Conditions Related to Synovial Fluid
An excessive buildup of fluid around a joint, known as joint effusion, can indicate various health problems. This can be caused by conditions such as arthritis or infections. Conversely, insufficient synovial fluid can lead to increased friction and joint pain.
