This medical illustration series depicts the anterior displacement of the temporomandibular joint, or TMJ, from the RIGHT side. Two illustrations of a lateral (side) view of the skull show the mandible (jaw) open and closed, revealing the displacement of the TMJ meniscus. To the immediate right are two enlarged cut-away sections of the dysfunctional TMJ showing the area in more detail. Labeled structures include the pterygoid muscle, mandible, temporal bone, meniscus, condyle and joint capsule.
