The lining inside the joint capsule that produces synovial fluid.
Used by AQA
Paper 1
Revise: Synovial joint structureThe synovial membrane lines the inside of the joint capsule and produces synovial fluid. Its protective role is linked to this production: the fluid it supplies reduces friction during movement.
Distinguish the synovial membrane, which produces synovial fluid, from the fluid itself, which lubricates the joint.
When identifying structures on a diagram, check where the label line ends: the joint capsule is the outer covering, while the synovial membrane lines its inside.
