Features of Amphibian Gastrulation

Major features of amphibian gastrulation are:

• Ectoderm surrounds the embryo by Epiboly.
• Gastrulation is initiated by a limited invagination of endodermal cells.
• Formation of archenteron is completed as a result of involution of endoderm.
• Gastrulation begins on the future dorsal surface of the embryo.
• Blastocoel is finally obliterated.
• Mesoderm and most endoderm are internalized by involution over dorsal, lateral and ventral lips of blastopore.
