The process of gastrulation

(A) The blastula stage, prior to any gastrulation movement.

(B) Movement of the blastula cells preliminary to gastrulation.

(C) Blastoporal view of successive phases of gastrulation; (solid line) lip of blastopore, {dotted line) germ ring, to be subsequently incorporated into the blastoporal lips.

(D) Lateral view of sagittal section during late gastrulation showing the origin of the mesial notochord, and the lateral mesoderm from the proliferated chorda-mesoderm cells at the dorsal lip.

(E) Composite drawing to illustrate the germ layer relations in the later gastrula of the frog. The medullary plate (ectoderm) is not indicated; {alternate dots and dashes) notochord, {heavy stippling) notochord, {sparse stippling) mesoderm, (cellular markings) ectoderm.

Pages where the terms "Historic" (textbooks, papers, people, recommendations) appear on this site, and sections within pages where this disclaimer appears, indicate that the content and scientific understanding are specific to the time of publication. This means that while some scientific descriptions are still accurate, the terminology and interpretation of the developmental mechanisms reflect the understanding at the time of original publication and those of the preceding periods, these terms, interpretations and recommendations may not reflect our current scientific understanding.
