WebJul 25, 2024 · As embryos develop, they follow predetermined patterns of tissue folding, so that individuals of the same species end up with nearly identically shaped organs and very similar body shapes. MIT scientists have now discovered a key feature of embryonic tissue that helps explain how this process is carried out so faithfully each time. WebScript: Between 3 and 4 weeks, the body plan emerges as the brain, spinal cord, and heart of the embryo are easily identified alongside the yolk sac. Rapid growth causes folding … WebLateral folding (or flexion) - the lateral edges of the embryonic disc flex sharply ventral. The edges of each germ layer make contact at head and tail regions and zipper toward the umbilicus. The ectoderm now covers the entire body surface except at the umbilical region where the connecting stalk and yolk sac merge. check discover card application status online
