Synovial membranes are connective tissue membranes that line the cavities of the freely movable joints such as the shoulder, elbow, and knee.
Membrane
A membrane is a selective barrier; it lets some items pass but prevents others from doing so. These entities could be ions, molecules, or other tiny particles. Biological and manufactured membranes are the two broad categories into which membranes can be placed. Cell membranes, which are the exterior coverings of cells or organelles that permit the passage of specific components, nuclear membranes, which enclose the cell nucleus, and tissue membranes like mucosae and serosae are all examples of biological membranes. Humans create synthetic membranes for use in laboratories and industries (such as chemical plants).
