Subsequently, one may also ask, what are the 3 stages of fetal development?
There are three stages of prenatal development: germinal, embryonic, and fetal. Prenatal development is also organized into three equal trimesters that do not correspond with the three stages. The germinal stage occurs from conception until 2 weeks (implantation), during which the zygote begins to rapidly divide.
Additionally, how a baby develops from conception to birth? The egg can be fertilized for 12 to 24 hours after it's released as it travels down the fallopian tube toward the uterus. If an egg meets up with a sperm cell that has made its way into the fallopian tube, it combines into one cell, a process that's known as fertilization or conception.
Likewise, people ask, what is the most critical stage of prenatal development?
The germinal period begins with conception and ends when the blastocyst is fully implanted into uterine tissue. Next, the embryonic period lasts from implantation until about 8 weeks from the time of conception. This is the most crucial period of prenatal development.
What is the last organ to develop in a baby?
Week 6: The neural tube closes Just four weeks after conception, the neural tube along your baby's back is closing. The baby's brain and spinal cord will develop from the neural tube. The heart and other organs also are starting to form.
