Which stage occurs after 12 weeks in TMJ development?

Explanation:
Understanding how the TMJ forms in stages shows that after the initial mesenchymal condensation (blastemic stage) and the formation of a joint space (cavitation), the next phase is maturation. During maturation, the tissues differentiate into the joint’s functional components—the articular disc, the joint capsule with its synovial lining, and the mature articular surfaces. Ossification of the condyle and surrounding bone occurs later, after this differentiation completes. So, the stage occurring after about 12 weeks is maturation.
