Accepted Answer

The open space within the gastrula is called the archenteron, which eventually becomes the gut or digestive system of the organism. The ectoderm, mesoderm, and endoderm are the three primary germ layers that differentiate from the blastula during gastrulation. Neural crest cells are a type of cell that arise from the ectoderm during development and give rise to a variety of cell types, including neurons and glial cells.
