synovial layer
Quick Summary
The synovial layer is an inner lining within synovial joints, which are a type of permanent joint that contains fluid. This layer, composed of connective tissue, secretes synovial fluid. This fluid is crucial for joint health, acting as a lubricant and providing nutrients to the joint cartilage. The synovial fluid is a dialyzate of blood plasma, rich in hyaluronic acid, which gives it viscous and elastic properties. These characteristics allow it to form lubricant films between moving joint surfaces, aiding in nutrition and smooth motion. Inflammation of this synovial membrane is known as synovitis.123
