Delineate the characteristics and periods in prenatal development.

Prenatal development is a crucial stage in human life, beginning from conception and continuing until birth. This period involves a series of complex biological and physiological changes, resulting in the formation of a fully developed organism. The process of prenatal development is divided into three main stages: the germinal stage, the embryonic stage, and the fetal stage. Each stage is characterized by distinct processes and developmental milestones that lay the foundation for physical, cognitive, and emotional growth.

### Germinal Stage (Weeks 1–2)
The germinal stage begins at conception when a sperm fertilizes an egg, forming a zygote. This stage is marked by rapid cell division and the formation of a ball of cells called a blastocyst. The first few days after fertilization are critical for cell differentiation, where cells begin to specialize into different types that will eventually form the body’s tissues and organs. During this stage, the zygote travels down the fallopian tube and implants itself into the lining of the uterus. Implantation is a pivotal event, as it signals the transition from the single-cell zygote to a multi-cellular organism.
