Let's take a closer look at the major stages and events that take place during the prenatal period of development. The process of prenatal development occurs in three main stages. The first two weeks after conception are known as the germinal stage, the third through the eighth week is known as the embryonic period, and the time from the ninth week until birth is known as the fetal period.
This essay discusses its stages, their landmarks, and what environmental influences can occur throughout the entire prenatal process. The prenatal stage is not just about growth, but involves various complex processes that can be affected by external forces.
Prenatal Development. How did you come to be who you are? From beginning as a one-cell structure to your birth, your prenatal development occurred in an orderly and delicate sequence. There are three stages of prenatal development: germinal, embryonic, and fetal. Let’s take a look at what happens to the developing baby in each of these stages.Prenatal development is the process that occurs during the 40 weeks prior to the birth of a child. There are three stages of prenatal development: germinal, embryonic, and fetal.Prenatal development is also organized into three equal trimesters, which do not correspond with the three stages.Prenatal development in humans is broken into three separate trimesters, or stages, through which the fetus must develop. Those stages are discussed below. Prenatal Development Stages. Human prenatal development is broken into three trimesters, as seen in the graph below. First Trimester. Pregnancies are measured from a woman’s last menstruation.
Prenatal Development. complex system of cells that allows for the fetus to maintain homeostasis and function in the world independent from it’s prenatal life source. The fetus transitions through three distinct periods of prenatal development, germinal, embryonic, and fetal arriving at the end of the third trimester with organized systems that allows for regulated functioning.
Prenatal Development Prenatal development is the period in development from conception to the onset of labor. Perinatal period is the period beginning about the seventh month of pregnancy and continuing until about four weeks after birth. Postnatal development is the period in developme.
Prenatal development: The process of growth and development within the womb, in which a single-cell zygote (the cell formed by the combination of a sperm and an egg) becomes an embryo, a fetus, and then a baby. The first two weeks of development are concerned with simple cell multiplication. This tiny mass of cells then adheres to the inside wall of the uterus.
This lesson explores the stages of prenatal development and a mother's ability to affect her unborn child. Introduction You're probably wondering how what happens to a baby before it's born is.

Development happens quickly during the prenatal period, which is the time between conception and birth. This period is generally divided into three stages: the germinal stage, the embryonic stage, and the fetal stage. Stage 1: The Germinal Stage. The two-week period after conception is called the germinal stage.
Essay Instructions: uring a healthy pregnancy, the womb provides a protective environment for the fertilized egg (or zygote) to develop into an embryo, and then into a fetus.This maturation process supports the unfolding of the genetic code that is specific to each individual. However, a child's prenatal environment also has an impact on development.
The prenatal stage of development lasts about 38 weeks. The three stages that make up prenatal development are the germinal stage, the embryonic stage, and the fetal stage. The germinal stage makes up the first two weeks of prenatal development, from conception to implantation, where the zygote implants itself into the uterine wall.
Review the stages of prenatal development. Explain how the developing embryo and fetus may be harmed by the presence of teratogens and describe what a mother can do to reduce her risk. Conception occurs when an egg from the mother is fertilized by a sperm from the father.
Prenatal risks. Risks during the prenatal period include the following. Adequate nutrition for the mother is imperative. Maternal malnutrition may affect not only the size of the infant but also the development of systems such as the immune system or the brain. Teratogens are agents or substances that can produce developmental malformations.
