Fetal what appearance be? (16 weeks)

Gravid Zhou Shi's fetal 16 main organs had been formed. The bag of a water that makes by caul, amnion bursa, supporting fetal life jointly together with placenta. Just be like the helmet that makes sure astronaut life place needs.

Amnion bursa but the temperature that amortize collides to still can keep in order to protect fetal; constant and enough space make fetal footloose in warm environment exercise limbs activity. The amniotic fluid in amnion bursa offerred a liquid for fetal exercise deglutition. When your about to give birth, whole fetal bag oppresses through dead water pressure palace neck aids its dilate. Amniotic fluid is salty, so, fetal inside the mother's body very marine like biology.

Fetal meeting loop, turn first, magnify mouth, make like deep breathing bosom, the abdomen rises and fall. He returns meeting absorb and deglutition even hiccup, yawn, stretch oneself, knit brows. Although be in gravid 20 you may not feel before Zhou Zhi, but your darling can be done really.

Went to 16 weeks, fetal body length achieves 12 centimeters (arrive from the beginning buttock) , weight amounts to 130 grams. Although the child is very small, but had formed limb and facial feature, scale is relatively well-balanced. Because lack adipose deposit, fetal and special thin and small, and the skin is thin and transparent, can see hypodermic blood vessel. At this moment fetal performance is brisker, but with the make a fist, absorb finger, get down or eduction amniotic fluid.

The head

Cover character has been formed, so scanning sees apparent facial feature, wait for a feature with the mouth nasally for example. Because formed facial muscle, so, fetal and OK make a few aimless expression. Fetal although be in the condition that does not have the light,fall, but the change that the eye begins to be able to feel the light, begin to form careful eyelid and eyelash. Go out on the tongue show taste bud. When going to 16 weeks, ear bone hardens, can hear voice.

Upper limbs and lower limbs

Lower limbs begins to achieve a balance with the development of upper limbs, grow slightly than upper limbs a few. Ministry of hand finger tip appears small fingernail, but toe still does not have occurrence toenail.

Neurological

Begin to form with surface of muscle connective nerve adipose () of phosphatide calling pith, deliver and coordinate motion of signal of this pair of nerve to having important sense. Because be perfected neurologically inside fetal body, the child's motion is strengthened apparently.

Fetal life maintains a system

Inside yolk bursa, there is the amniotic fluid of a protection all round the child, fetal can move freely inside, be helpful for forming good muscle pulling force. Fetal head but can gadarene, and the following day the head likelihood on face, you won't feel fetal to these move commonly, because arrived since amniotic fluid,decrease display vigour to use.

Fetal the function in this phase

Fetal cerebra, neurological had established a connection with muscle, can make very complex motion, can extend bend finger and limb. Below scanning, you can see the child has absorb finger to perhaps capture umbilical phenomenon possibly. The from time to time inside fetal bladder is filled into amniotic fluid, platoon of from time to time is empty, this is to be in prepare for the following function.

Although fetal in 13 weeks when can make more harmonious motion, but the movement that you sense very hard fetal, fetal the amniotic fluid all round is very big to arriving since fetal motion decrease display vigour to use. Some pregnant woman thought 16 Zhou Shi, can feel in next abdomen picture " butterfly fan wing " same exercise, but this is very scarce. As be brought up fetally, you are OK more and more apparent ground feels quickening.
