All of the following statements about synovial fluid are true, Except -: (A) Secreted primarily by type A synovial cells, (B) Follows Non - Newtonian fluid kinetics, (C) Contains hyaluronic acid, (D) Viscosity is variable
Answer is A. Synovial fluid is secreted by type B synovial cells (type B synoviocytes).
The viscous and lubricating property of synovial fluid is attributed to hyaluronic acid.
Synovial fluid is a non-newtonian thixotropic fluid and its viscosity is variable : viscosity decreases with increased rates of shear (increased speed of joint movement).
