One development that takes place in the fourth week, it is extremely important for your baby.This is the time of active development of extraembryonic organs - chorionic amnion and the yolk sac.It was during the fourth week of the fertilized egg begins to turn into an embryo.

uture moms.During this period, the embryo is actively developing.
blastocyst (roughly a bubble in which the fertilized egg) inside the uterus is attached to its upper part.Endometrium surrounds the ovum.At the time of strengthening of the blastocyst in the mucosa cells of the future placenta (trophoblast) are already producing hormone - human chorionic gonadotropin (hCG).It is the content of this hormone in urine tests help detect pregnancy.
On the eighth day after fertilization, the embryo is transformed into a prototype of a future bubble of membranes (amniotic cavity) and the yolk sac.The amniotic cavity surrounded by a thin membrane, called - amnion, which is filled with amniotic fluid.From
constantly dividing cells of the body of your baby in the yolk sac begin to form medium, the internal and external views of germ layers:
endoderm (inner layer) - is responsible for the formation of the internal organs: lungs, liver, bladder, pancreas, digestive and respiratory systems.
mesoderm (middle layer) - is responsible for the spine, skeletal muscle, muscular system, cartilage, kidney, heart, blood, large vessels, gonads, lymph.
ectoderm (outer layer) - is responsible for the nails, tooth enamel, hair, eye lenses, skin, epithelial tissue of the eyes, ears and nose.As will form the nervous system (nerves, brain, sensory receptors of the nose).
The three germ layers are covered prototypes of the future of your child.

By the end of the fourth week of the baby's face is different and the beginnings cute eye.There are already the beginnings of internal organs.And the most interesting fact - this is the beginning of the vestibular apparatus in a child at this early period.
