Synovial tissue and synovial fluid.

Abstract

Synovial tissue is a highly specialized tissue that keeps the articular joint well lubricated, and at the same time provides nutrients to the articular surface. A joint needs a small amount of synovial fluid to work. Although the tissue structure is simple, its function is highly sophisticated. Because synovial tissue is the target of most autoimmune diseases, joints need to be understood in their entirety to create new treatments for such immunological disorders.
