Lips, eyes, nose, tongue, boobies… we have covered many aspects of human body and we will cover more but in the meantime, how about exploring the very origin of a human body? Yes, we want to talk about interesting Fetal and Embryonic facts that will simply make your jaws drop! Are you ready for this interesting journey? You guys are awesome and we know that you crave for knowledge. So, we will take it for granted that you are ready!
Interesting Fetal and Embryonic Facts: 1-10
1. Life inside a woman’s womb starts as a single cell. This cell is so small that it is literally invisible to naked eyes. Gradually the cell divides and multiplies and by the time the baby is actually born, there are two hundred million cells! The total weight of these 200 million cells is 6 billion times the weight of the egg that was fertilized.
2. It is not that the sperms race for the egg. It is rather the other way round. The egg selects the best sperm. Once the egg finds the best sperm, it opens up and takes the sperm in and then closes. The sperm that goes inside fails to come out. The egg preys on it by distilling out the chromosomes from it.
3. Recent studies however show that more than one sperm can enter an egg but only one manages to enter the nucleus.
4. Human beings remain vertebrates even in embryonic stage.
5. The development of a child’s brain is dependent on three factors. 60% of the development is determined by genes, 10% by the diet of the mother and 30% by the environment inside the uterus.
6. The genes are actually responsible for basic brain development’s blueprint creation. The final pathway, location and interrelationships between neurons are, to a great extent, dependent on wellbeing of mothers, early nutrition, mood and habits like alcohol and smoking.
7. The mood or emotions of the mother determine how the developing brain gets hardwired. This happens because neurotransmitters and hormones travel across placenta to the fetus’ developing brain through the bloodstream.
8. Studies reveal that external sound stimuli are also responsible for the growth of brain cells developing in utero. This happens when the brain rapidly matures from 24th week onward.
9. Unborn babies feel pain as strongly inside the womb as those outside the womb.
10. The greatest change of an embryo in terms of physical change and size takes place in the first month after fertilization.
