The prenatal period is characterized by three major sub periods: Germinal‚ embryonic and period.

The embryonic period began from two to eight weeks‚ when the cephalacadual and proximodistal

There are three stages of prenatal development: germinal‚ embryonic and fetal. The germinal stage is fertilization to 2 weeks. The first cell is created when a sperm (a male reproductive cell) pushes through the membrane of the ovum (the female reproductive cell). The new cell is then formed by the process of fertilization
