The articular disk is a thin, oval plate, placed between the condyle of the mandible and the mandibular fossa. Its upper surface is concavo-convex from before backward, to accommodate itself to the form of the mandibular fossa and the articular tubercle.Click to see full answer. Keeping this in view, where are articular discs found?Disks are found in the temporomandibular joint of the lower jaw, the sternoclavicular (breastbone and collarbone) joint, and the ulnocarpal (inner forearm bone and wrist) joint. A pair of menisci is found in each knee joint, one between each femoral condyle and its female tibial counterpart.Similarly, what is articular disc disorder? The most common form of internal temporomandibular joint derangement is anterior misalignment or displacement of the articular disk above the condyle. Symptoms are localized joint pain and popping on jaw movement. Treatment is with analgesics, jaw rest, muscle relaxation, physical therapy, and bite splinting. Keeping this in view, why is articular disc important? 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.Do all synovial joints have articular discs?Many, but not all, synovial joints also contain additional structures: Articular discs or menisci – the fibrocartilage pads between opposing surfaces in a joint. Articular fat pads – adipose tissue pads that protect the articular cartilage, as seen in the infrapatellar fat pad in the knee.
