The '''articular disk''' (or '''disc''') is a thin, oval plate of [[fibrocartilage]] present in several [[joints]] which separates synovial cavities. This separation of the cavity space allows for separate movements to occur in each space.
The presence of an articular disk also permits a more even distribution of forces between the articulating surfaces of bones, increases the stability of the joint, and aids in directing the flow of synovial fluid to areas of the articular cartilage that experience the most friction.
The term "[[Meniscus (anatomy)|meniscus]]" has a very similar meaning.<ref>[http://anatomy.med.umich.edu/modules/joints_module/joints_13.html Module - Introduction to Joints<!-- Bot generated title -->]</ref>
