Embryonic folding

Definition

Embryonic folding is the process during early embryonic development where the flat, three-layered embryo transforms into a three-dimensional structure with distinct head and tail ends as well as internal gut tube formation. This crucial step establishes the basic body plan of the organism.

Gastrulation: Gastrulation is an earlier phase of embryonic development where the cells are rearranged to form three primary layers (ectoderm, mesoderm, and endoderm), setting the stage for embryonic folding.

Neurulation: Neurulation follows embryonic folding and involves the development of the neural tube along the back of an embryo, which eventually forms the central nervous system.

Organogenesis: Organogenesis is the process by which organ rudiments develop from the three germ layers after embryonic folding has established the basic body plan
