Discuss the structure of a synovial joint. What are the structures in it and what are their functions?

-It is a movable joint
-It is a diarthrosis
-Between the articular surfaces is a cartilage, usually hyaline cartilage
-It has a capsule around the joint, which has a tougher outer lining. The outer lining has often got ligaments in it, the inner lining is a synovial membrane
-The synovial membrane produces synovial fluid which lubricates the joints and nourishes the cartilage
-Example is the hip

and elastic tissues
-For example, it holds muscle fibres together and
