During TMJ development, articulator spaces form during which stage?

Explanation:
Articulator spaces form during the cavitation stage, when the dense mesenchymal tissue in the future joint region hollows out to create the synovial joint cavity. In TMJ development, this cavitation occurs roughly in weeks 9–11, and it’s what allows the joint to separate the condyle from the temporal bone and to accommodate the articular disc, giving rise to the superior and inferior joint spaces. Before cavitation, the area is a solid condensate; after cavitation, maturation and ossification proceed to shape and harden the surrounding structures.
