synovial membrane

[sə′nō·vē·əl ′mem‚brān]
A layer of connective tissue which lines sheaths of tendons at freely moving articulations, ligamentous surfaces of articular capsules, and bursae.

Synovial Membrane


the inner layer of an articular capsule or osteofibrous canal through which muscle tendons pass. A synovial membrane consists of connective tissue and is fined with endothelium. It produces synovia. Villi cover the membrane, thereby enlarging its surface. The synovial membrane is rich in blood vessels, lymphatics, and nerve endings. Metabolic processes between synovia and blood occur in a synovial membrane.
