embryonic development gastrulation

Embryonic Development - All the events which change a zygote into a fully developed organism is called embryonic development. The entire process of development is called embryogenesis. Von Bear is called the "Father of Modern Embryology". ..

Gastrulation is an important dynamic process in the development of the zygote which involves movement of cell masses from the surface of the blastula to their definitive positions in the embryo and their three primary germinal layers i.e., ectoderm, endoderm and mesoderm. ..

. The first half of the phase and the changes in these phases are controlled by estrogens and progesterone. The secretion of these hormones occur cyclically because of the cyclic secretions of pituitary gonadotropins in the female. The fertilised ovum in mammals and other higher animals passes thro..

It is well developed in reptiles, birds and prototherians. It is mainly digestive in function so it acts as an extra embryonic gut. In human beings it is vestigi..

Cell division forms a mode of reproduction in unicellular organisms. In multicellular organisms it is responsible for embryonic development and growth of the adult organism. It is also involved in repair and regeneration. Both asexual and sexual reproduction requires cell divisi..

Pseudocoelomata In Pseudocoelomata a false body cavity is present. It is called pseudocoelom. It is a body cavity which is not lined by mesoderm. This condition is seen in round worms (Aschelminthes). It develops from the first formed embryonic body cavity called blastocoe..

Differentiation is the process by which the unspecialised embryonic cells change in structure and function during development and growth of an organism to form specialised cell types, tissues, and organs, distinct from one another. Differentiation makes cells of the same g..
