What are the three stages of human prenatal development called?

Human prenatal development is the time between conception and birth. The time for human growth and development is divided into three stages: the germinal stage, the embryonic stage and the fetal stage.

The first 2 weeks after conception is called the germinal stage. Conception occurs when a sperm cell combines with an egg cell to form a zygote.

The second stage of prenatal development is called the embryonic stage which lasts from the end of the germinal stage to two months after conception. The developing ball of cells is then called an embryo. In this stage, all the major organs form, and the embryo becomes very fragile.

The final stage of prenatal development Is called the fetal stage which lasts from two months after conception till birth. In this stage the sex organs begin to form, bones and muscles form and movement inside the uterus occurs.
