It would be placer because you are not digging up any ground..if that is not right it might be none because if you are messing with water environments you are still messing with it which could not be good
The correct answer is "synovial membrane." The synovial membrane is a tissue that primarily produces synovial fluid between the joints which serves as a lubricant. Apart from making synovial fluid, it lines joint cavities, tendon sheaths, and the bursa which is a sac filled with fluid that is located between the tendons and the bones.
