Brain Development of the Embryo
The first two months of pregnancy mean a lot of changes for both the pregnant mother and the baby. Embryos develop rapidly and change drastically every day. An embryo's brain develops quickly during this time, so it is important to provide a safe home for it to encourage healthy growth.

The Embryo
-
The embryonic phase is actually a relatively short one. It begins at approximately 5 weeks, and at about 8 weeks it is considered a fetus. A lot happens in those short few weeks, however.
The Neural Tube
-
In the 5th and 6th weeks, the neural tube develops and closes. This is what will eventually turn into the spinal cord and the brain. At this time, the brain is already developing into 5 different areas, and cranial nerves are present.
-
The Head
-
The head begins to develop during the 7th week. Other features, such as eye lenses and nostrils, are also beginning to form.
Helping Development
-
A pregnant woman should be extra careful to take care of herself in order to help the baby develop properly and avoid birth defects that could affect its development. A healthy diet, prenatal vitamins, and avoiding alcohol and drugs are just some of the ways to keep the embryo's brain grow properly.
Fetal Growth
-
After those 8 weeks are over, the embryo will be considered a fetus. In the following few weeks, the fetus's head will end up being half the size of its body, and brain functions will develop rapidly---the fetus will soon be able to hear and make movements.
