Thereof, what are articular disc made of?

Articular disk of the temporomandibular joint. The articular disk is a thin, oval plate, which is made from fibrous connective tissue, non vascular, placed between the condyle of the mandible and the mandibular fossa.

Likewise, 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.

Then, which joints contain articular discs?

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.

What is articular surface?

any surface of a skeletal formation (bone, cartilage) that makes normal direct contact with another skeletal structure as part of a synovial joint; bony articular surfaces are usually covered with articular cartilage.
