Describe the Three Stages of Prenatal Development, Including the Number

Question

Examlex · Accepted Answer

The Answer is The three stages of prenatal development are the germinal stage, the embryonic stage, and the fetal stage.

1. Germinal stage (0-2 weeks post-conception): This stage begins at conception and lasts for about two weeks. During this stage, the fertilized egg, or zygote, undergoes rapid cell division and travels down the fallopian tube to the uterus, where it implants in the uterine wall.

2. Embryonic stage (3-8 weeks post-conception): This stage begins around the third week and lasts until the eighth week after conception. During this stage, the major organs and systems of the body begin to form. The embryo is particularly vulnerable during this stage, as exposure to harmful substances can cause birth defects.

3. Fetal stage (9 weeks post-conception to birth): This stage begins around the ninth week and continues until birth. During this stage, the fetus grows and develops rapidly. Organs continue to mature, and the fetus becomes more active. By the end of this stage, the fetus is ready to be born.

It's important to note that these timeframes are approximate and can vary from one pregnancy to another.
