Synovial Membrane of Articular Capsule of Glenohumeral Joint
Membrana synovialis capsulae articularis articulationis glenohumeralis
Read moreAnatomical Relations
The synovial membrane of the glenohumeral joint forms the internal layer of the articular capsule of the glenohumeral joint. The fibrous membrane forms the external layer of the capsule.
The tendon of the long head of biceps brachii muscle passes through the glenohumeral joint within the synovial membrane, and the synovial membrane extends and continues with the tendon as far as the surgical neck of the humerus.

Structure
The synovial membrane of the glenohumeral joint lines the joint cavity and is composed of loose connective tissue. The synovial membrane is responsible for producing synovial fluid, which lubricates the glenohumeral joint.
Function
The articular capsule of the glenohumeral joint ensures that the joint is sealed, thus, keeping the lubricating synovial fluid within the joint. It provides passive stability to the joint by limiting the joint movement. Additionally, it provides active stability but containing numerous proprioceptive nerve endings which relay mechanical information back to the central nervous system (Ralphs and Benjamin, 1994).
