Synovial fluid

Synovial fluid, also called synovia,^{[help 1]} is a viscous, non-Newtonian fluid found in the cavities of synovial joints. With its egg white–like consistency,^[1] the principal role of synovial fluid is to reduce friction between the articular cartilage of synovial joints during movement.^[2] Synovial fluid is a small component of the transcellular fluid component of extracellular fluid.
