Different stages of EMBRYO

         
       Hello frndzzz.......Followed by the implantation of embryo into the womb, we are going to share about the different stages of embryo.....

1.When 0 days old :

                                At first  the embryo consist of a single cell, protected by a thick coat, it drifts slowly down the fluid-filled fallopian tube,pushed along by the tiny hairs that line the inner surface..

2.When 4 days old:

                             About a day after fertilisation, the cell divides into two...Twelve or so hours later, it divides again After 4 days the embryo is a ball of 32 small cells and looks like a berry

3.When 1 week old:

                            The embryo has now entered the uterus and attached itself to the inner wall, anchoring itself with finger like growths that will help it feed from the mother's blood..

4. When 2 weeks old:

                                    A week later, the embryo has developed a yolk sac and a fluid filled space called an "AMNION". Inside the amnion is a layer of cells called the embryonic disc that will develop into a body

5. When 3 weeks old:

                                The embryonic disc grows rapidlyand folds into a curved shape.Within a matter of days, it develops a head, tail, blood vessels and the beginning of major internal organs.

6. When 4 weeks old:

                                : Now at the size of a bean, the embryo has the beginnings of arms and legs and it;s heart starts beating.. Nerves and muscles develops and eyes begin to format first without eyelids...
