<prompt> All of the following statements about synovial fluid are true, Except -Secreted primarily by type A synovial cellsFollows Non - Newtonian fluid kineticsContains hyaluronic acidViscosity is variable  <response>: 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.
