Question

Quizplus · Accepted Answer

Cephalocaudal folding occurs after the formation of the primary germ layers, not before. This process is crucial for the development of the embryo's body structure, including the head and tail regions, and is driven by differential growth rates in various parts of the embryonic disc. It typically happens during the third and fourth weeks of embryonic development.
