Question

Differentiate synovial fluid and synovial lining?

a) Synovial fluid lubricates joints, while synovial lining covers the joint surfaces.
b) Synovial fluid covers joint surfaces, while synovial lining lubricates joints.
c) Both synovial fluid and synovial lining lubricate joints.
d) Synovial fluid and synovial lining have the same function

Answer 1

Synovial fluid is the lubricant within a synovial joint, while synovial lining refers to the synovial membrane that produces the synovial fluid and covers joint surfaces.

Step-by-step explanation:

The correct answer to the question differentiating synovial fluid and synovial lining is Option (a): Synovial fluid lubricates joints, while synovial lining covers the joint surfaces. Synovial fluid is a thick, slimy fluid secreted by the synovial membrane that provides lubrication to reduce friction between the bones of a joint, as well as nourishment to the avascular articular cartilage. The synovial lining, or synovial membrane, is the inner layer of the articular capsule that envelops a synovial joint, and its cells are responsible for producing the synovial fluid. Together, they enable the smooth movement and functionality of the joint.
