The thumb possesses a saddle joint where each articular surface has both a concave and a convex surface.
What will be an ideal response?
The ends of each bone are covered with hyaline cartilage that is continuous with the synovial membrane enclosing the joint. Synovial fluid fills the space between the articular cartilage. Outside the synovial membrane there is a very tough, fibrous capsule that prevents the synovial membrane from bulging out as pressure is applied to the ends of the bones.
