Articular disk of the temporomandibular joint
（重定向自Temporomandibular joint disk）
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.
Its upper surface is concavo-convex from before backward, to accommodate itself to the form of the mandibular fossa and the articular tubercle.
