Synovia
Synovia
Synovia (pronunciation: sih-NOH-vee-uh), also known as synovial fluid, is a viscous, non-Newtonian fluid found in the cavities of synovial joints. The primary role of synovia is to reduce friction between the articular cartilage of synovial joints during movement.
Etymology
The term "synovia" comes from the Greek word "syn" meaning "with" and "ovum" meaning "egg", referring to the egg-white like consistency of the fluid.
Function
Synovia is secreted by the synovial membrane and performs several functions in the joint. It lubricates the joint, provides nutrients to the cartilage, and removes waste products. It also contains phagocytic cells that remove microbes and the debris that results from normal wear and tear in the joint.
