The articular membrane consisting of specialized endothelial cells that have the ability to produce a fluid that fills the joint cavity.
A smooth membrane which forms the inner lining of the capsule covering a joint and secretes the fluid which lubricates the joint.
Membrane, secreting synovial fluid, that covers freely movable joints; also called synovium.
The membrane, composed of mesothelium and connective tissue, that forms the sac enclosing a freely movable joint. It secretes the lubricating synovial fluid.
A benign or malignant tumor of the synovial membrane. Benign synoviomas occur on tendon sheaths; malignant synoviomas (synovial sarcomas) may occur where synovial tissue is not normally found, e.g. in the esophagus.
This forms the lining of the soft parts that enclose the cavity of a joint.
The membrane lining the capsule of a joint and secreting synovial fluid. The synovial membrane is pink, smooth, and shiny and is made of an intima lining a stronger, vascular fibrous membrane. The intima contains synoviocytes (fibroblast- and macrophage-like cells), which remove debris from the synovial fluid and synthesize some of the mucin (specifically, hyaluronic acid) of the synovial fluid. Most of the synovial fluid is filtered from the blood vessels of the outer fibrous layer of the synovial membrane.
The inner lining of the articular capsule of a joint, known as the synovial membrane, which generates synovial fluid for lubrication purposes.
The membrane that covers the surfaces of bones where they come together in a joint and also lines the inner surfaces of ligaments.
