In addition, he also presented several structures present in these embryonic formations and their respective functions, such as the Blastopore, Archenteron, Endoderm, Mesentoderm and Ectoderm and more. Embryology is a fascinating part of Biology, which has been increasingly required in Enem and other entrance exams. Therefore, it is essential that you master all the concepts in this class. Yes, there are many, but with the explanation of the professor, you will be able to master them. You will never again confuse the Segmentation Types (Holoblastic and Meroblastic) and the egg development phases (Morula, Blastula, Gastrula and Neurula).
