All the statements below about synovial fluid are true except:

a. arthrocentesis is performed as a means to evaluate arthritis and other joint disorders

b. synovial fluid is present only in moveable joints

c. joint fluid resembles plasma in viscosity

d. joint fluid has approximately the same glucose as plasma

The right answer is C.

Synovia is a viscous biological fluid located at the joints and fulfilling several functions. It limits bone friction between them, dampens shocks, provides the nutrients and dioxygen necessary for chondrocytes (cartilage cells) while eliminating their metabolic waste, and benefits from the presence of immune cells to eliminate possible body foreigners.
