Discus articularis
From WikiLectures
The discus articularis is a plate of fibrous cartilage that is inserted between the articular surfaces of some joints. They thereby divide the joint cavity into two parts (unlike menisci). Their function is to equalize the curvature of uneven joint surfaces, and as flexible inserts, they increase the mobility of the joints.
Development of articular discs[edit | edit source]
Part of the mesenchyme of the future joint turns into fibrocartilage, which remains between the bases of the bones and is fused with the joint capsule at its edges.
Examples of Occurrence[edit | edit source]
- Articulatio temporomandibularis.
- Articulatio sternoclavicularis.
- Articulation of ulna and carp (articulatio radioulnaris distalis).
- As a variety in articulatio acromioclaviculare.
