The Fetus Growth During Pregnancy

The Fetus Growth During Pregnancy
The Fetus Growth During Pregnancy;From the first day of your last period, The follicles that carry the egg will slowly begin to grow from the third day of your cycle on either or both of your ovaries. The time, from which you calculate your due date, which is nine months and seven days from this day. Well, there is nothing much to say, as your baby is about two weeks away from conception. The womb is getting itself ready the mucus in the cervix becomes thinner to enable the sperm to swim through it easily.

The follicle ruptures and releases an egg or ovum, which is approximately 0.13 mm in size. This egg travels up the fallopian tube and survives for about 24 hours. This is your highly fertile period.This is the stage where the central nervous system begins to develop by forming a niche in the top layer that extends to the tail end of the embryo. If the egg is not fertilized within this time, it passes out the next time you menstruate.

This cell multiplies into over a hundred cells and travels along your fallopian tube until it reaches the uterus by the fourth day after fertilization. The egg is now called blastocyst, This is the stage where the central nervous system begins to develop by forming a niche in the top layer that extends to the tail end of the embryo . It is made up of two layers that eventually become the placenta and the embryo. It floats about in the womb getting its nourishment from the secretion of glands situated in the lining of the uterus.

The embryo is completely embedded in the lining of the uterus and can be identified by an experienced gynaecologist through an ultra sound scan. the outer layer also forms the umbilical cord as well as the membranes that protect the baby This is the stage where the central nervous system begins to develop by forming a niche in the top layer that extends to the tail end of the embryo. The cells fold up to create a hollow neural tube that form your baby's brain and spinal cord.

The next twenty-seven weeks will see the fetus grow in size while its vital organs mature to full capacity to aid its survival outside the womb. The baby's major muscles are moving in tandem with the brain as he bends and twists his arms, wrists, elbows, fingers, legs, knees and toes. His nervous system has also begun to function The three tiny bones in his middle ear have begun to harden but the auditory centres in his brain have not developed as yet so he might not be able to make any sense of the sounds. He will look quite a sight, as he is wet and slippery, covered in vernix and traces of your blood.
