. 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..

Cell Division - 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 requ..

While the amniotic cavity is being formed, another cavity develops. This arises as an out growth from the hindgut which pushes its way into extra embryonic coelom. It is known as allanto..

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..

As the cells of the morula continue to divide, a cavity appears inside the morula. It forms the blastocoel. It separates a surface layer of blastomeres from an inner cell mass. The blastomeres on the surface of the embryo become flattened and form the trophoectoderm or trophoblast. This layer on fu..

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..
