Fecundation


Fecundation can be defined as the encounter and fusion of two gametes cells forming a new individual. Fertilization is divided in some parts, the passage of the sperm through the radiate corona, penetration of the spermatozoid in the zona pellucida, reaction acrossomic and fusion of the membranes of the oocyte and the spermatozoa, and soon afterwards the nesting that is the fixation of the already fertilized ovule On the wall of the uterus.

Gastrulation

Imagem
Gastrulation is the process that orginates the gern layers ( ectoderm,  mesoderm and endoderm.) While this process happens the embrionic disc, enitially bilaminar, is coverted into a trilaminar embrionic disc. During gastrulation the cells move into the embryo and the regions of the endoderm and mesoderm which are originally adjacent to the cell plate, they assume theirs apropiate positions in the ambryo.  Reference-WOLPERT.  L .

Embryonic leaflets

Imagem
 An embryonic leaflet is the primary layer of cells that will subsequently give rise to all other tissues and organs of animals during the process of organogenesis. The three embryonic leaflets, or germ layers, form during embryogenesis and, in vertebrates, are particularly pronounced. However, all Eumetazoas  produce two or three embryonic leaflets. Animals with radial symmetry, such as Cnidarians, produce two layers (the ectoderm and the endoderm) leading to the classification of diblásticos. Animals with bilateral symmetry produce a third camanda (the mesoderm), between the two other layers, leading to the classification of triblásticos.    They are formed in the second week of development of the embryo in the process of Gastrulation, where the formation of germ layers will occur.   Ectoderm will give rise to:   Epidermis and cutaneous attachments, all structures of the nervous system (brain, nerves, nerve ganglia and spinal cord) and epithel...

Blastocyst

Imagem
The blastocyst is an embryo formed between 4° to 5°days after the fertilization. We can observe the formation of blastula consisting of a set of cells and the formation of a central cavity, the blastocele.  The cells of the inner man cell, now called the embryoblast, are located in poles, while those of the outer mass the trophoblast flatten and from the epithelial wall of the blastocyst. The internal cell mass will give rise to the tissues of the embryo itself, while the external cell mass would from the trophoblast that later contributed to the formation of the placenta.  Reference:SADDLER, T.
