very cute human!!!

Babies are probably the cutest thing on this planet, besides puppies. Just like this adorable baby who’s picture I snagged off the internet, they can’t help but be inherently cute.

Ever stopped to think what is going on in the tummies of these women who are carrying these precious babies? I haven’t really either, not until I found out one of my dearest friends is having a kid and is forcing me to be there in the delivery room when she has her baby girl. She updates me all the time about the development of the baby and perfect timing for her since I am taking my child psychology class where I can help her learn new things that she hasn’t found out yet too.

So, until I can tell you about that wonderful birthing experience, I’ll inform you guys of what happens to that cute baby from conception to birth.

The time from fertilization (after conception) and till the moment the baby is out of the womb is the time when a lot of development is happening inside the belly, which we refer to it as prenatal development. This usually lasts for 38 weeks. It sometimes can be more or sometimes can be less since not all pregnancies go through the exact same time period.

This time can be split into three periods: germinal, embryonic, and fetal.

The germinal period happens two week period since conception. At this time the egg is called a zygote. This period involves the creation of the zygote, massive cell division, and the attachment of the zygote to the uterine wall.

The next period is the embryonic period. The embryonic period occurs from 2 to 8 weeks after the fertilization of the egg. In this period the egg goes from being a zygote to an embryo, which is when the mass number of cells become distinct to this one individual. In this period the you have the formation of the neural tube, which turns into the central nervous system, development of the head and features that come along with it, buds start to appear that will end up being the arms and the legs, and the development of basic organs. There is no sex distinction at the time of this period.

The final stage if the fetal stage. Here the embryo will now be known as a fetus. This time of development begins at the 9th week and will continue until birth, which makes it the longest period of development. In this stage, systems and organs that began to develop in the embryonic stage continue until complete development. The neural tube now develops into the brain and the spinal cord (central nervous system.) Also at this time do you see the sex organs begin to differentiate (XX, XY, or other variations.)

fetal period

Like I stated before, each pregnancy does not follow the EXACT same pattern, but they are relatively similar. Any differences can be due to problems of formation of certain organs or systems within the body. An example of this would be neural tube defects.

If you want to watch a more quick and condense video on prenatal development you can watch Alexander Tsiaras’s, a photographer, painter, and journalist, Ted Talk called “Conception to Birth – visualized
