Question

Quizplus · Accepted Answer

Gastrulation is the process by which the single-layered blastula is transformed into three germ layers - ectoderm, mesoderm, and endoderm - through a series of invaginations and cell migrations. These three germ layers give rise to all the body's tissues and organs. The neural tube forms during neurulation, which is a later stage of embryonic development. Somites are formed from mesoderm during segmentation, which takes place after gastrulation.
