Educators who understand prenatal development and factors affecting pregnancy can provide better support to students who may be dealing with these issues themselves or within their families. This knowledge can help educators create a more inclusive and empathetic learning environment, as well as identify potential risk factors that may impact a student's academic performance or well-being. It also allows educators to offer appropriate resources and referrals to support students and families during this critical stage of life.
Prenatal development begins at the moment of conception when a sperm fertilizes an egg to form a zygote. This zygote then undergoes rapid cell division and differentiation, eventually developing into a fetus.
Agents that have a negative effect on prenatal development are called teratogens. These can include drugs, alcohol, certain medications, infections, and environmental pollutants that can interfere with the normal development of the fetus.
The most vulnerable stage in prenatal development is during the first trimester, particularly between weeks 3 to 8. This is when the major organs and systems are forming and are most susceptible to teratogens, which are substances that can cause birth defects. It is important for pregnant women to take extra precautions during this critical period.
Factors that can affect prenatal development include the mother's health, nutrition, exposure to harmful substances (such as drugs and alcohol), genetics, and stress levels. Additionally, environmental factors like pollution and infections can also impact the development of the fetus.
The embryonic stage, which lasts from fertilization until around 8 weeks, is the most rapid period of prenatal development in humans. This is when the major organs and systems of the body begin to form.

Prenatal development begins at the moment of conception when a sperm fertilizes an egg to form a zygote. This zygote then undergoes rapid cell division and differentiation, eventually developing into a fetus.
First Stage: The first two weeks after conception are known as the Germinal stage. Second Stage: The next six weeks of development are known as the Embryonic stage. Third Stage: The remainder of prenatal development is known as the Fetal stage.
Embryology
Prenatal development occurs in three main stages: the germinal stage (first two weeks after conception), the embryonic stage (weeks 3-8), and the fetal stage (weeks 9-birth). During these stages, the fertilized egg undergoes cell division, differentiation, and organ formation, leading to the development of a fetus.
Alcohol
The last 7 months of prenatal development typically involve rapid growth and maturation of the fetus. Organs and systems continue to develop and reach functional levels, and the fetus gains weight in preparation for birth. During this time, the fetus also practices breathing and swallowing to prepare for life outside the womb.
Factors that can affect prenatal development include the mother's health, nutrition, exposure to harmful substances (such as drugs and alcohol), genetics, and stress levels. Additionally, environmental factors like pollution and infections can also impact the development of the fetus.

The germinal period is the shortest period of prenatal development, lasting approximately two weeks. This period begins at fertilization when the egg is fertilized by sperm and ends when the fertilized egg attaches to the uterine wall.
