Prenatal Stages and Development: Germinal, Embryonic & Fetal Period Video: Prenatal Stages and Development: Germinal, Embryonic & Fetal Period. In the 9 months before a baby is born, there is an enormous amount of prenatal development. In this lesson, you will explore the following stages of prenatal development: the germinal period, the embryonic period, and the fetal period.

What are the stages of prenatal development? The First Stage-The Germinal stage [Conception- 2 weeks]. This Stage only begins to occur after Conception, at this stage the sperm and egg have joined together and formed what many biologist call a Zygote, which is a fertilized egg.The Zygote then will travel from the Fallopian tubes which was the very site of it's origin and travel down to the mother's uterus.his Stage only begins to occur after Conception, at this stage the sperm and egg have joined together and formed what many biologist call a Zygote, which is a fertilized egg. The Zygote then will travel from the Fallopian tubes which was the very site of it's origin and travel down to the mother's uterus.

Fetal Development in the First Trimester: Stages & Timeline By the end of the first week, the embryo has made it to the uterus and is in the process of implanting itself into the uterine wall. From there, it enters the next stage of development, the formation of the three germ layers.

Human development (biology) The germinal stage refers to the time from fertilization, through the development of the early embryo, up until implantation. The germinal stage is over at about 10 days of gestation. The zygote contains a full complement of genetic material and develops into the embryo. Briefly, embryonic developments have four stages: the morula stage, the bastula stage, the gastrula stage, and the neurula stage.

- The stage of prenatal development that occurs from the end of the embryonic period until birth is called the fetal period. The most notable development during this stage is the dramatic change in size that takes place. This is the baby's final preparation for life outside the womb.

Stages of Prenatal 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 are known as the embryonic period, and the time from the ninth week until birth is known as the fetal period.

Development, Pregnancy, and Heredity What weeks of development does the pre-embryonic period include? The pre-embryonic period is the first 2 weeks of development (the first 2 weeks after fertilization), when the single cell produced by fertilization (the zygote) becomes a spherical, multicellular structure (a blastocyst). This period ends when the blastocyst implants in the lining of the uterus.

Prenatal Stages and Development: Germinal, Embryonic & Fetal Period Conception is also the beginning of the germinal period of prenatal development. This stage occurs during the first 2 weeks of development (or the 2nd - 4th weeks of pregnancy). The union of the sperm and egg cell forms a single cell called a zygote. The zygote moves along the Fallopian tube toward the uterus.

Chapter 3 The period of prenatal development that occurs two to eight weeks after conception. During the embryonic period, the rate of cell differentiation intensifies, support systems for the cells form, and organs appear.

- In the early embryo (ie: during the 4th and 5th weeks) it is difficult to be exact about the extent of each of these three regions, but as development proceeds, the distinctions become clearer. List the different parts of the digestive system derived from the foregut, midgut, & hindgut.

Prenatal development After fertilization, the process of embryogenesis (the early stages of prenatal development) begins. By the end of the tenth week of gestational age the embryo has acquired its basic form and the next period is that of fetal development where the organs become fully developed. This fetal period is described both topically (by organ) and chronologically (by time) with major occurrences being listed by gestational age.

- The embryonic development of the cerebral cortex is under the control of a number of genes. In the first trimester of fetal life, neurons arise in a region lining the cerebral cavity. Precursor cells in this proliferative zone give rise to neurons that migrate up and out into the cortex, forming its layers.

Embryonic Development Throughout this chapter, we will express embryonic and fetal ages in terms of weeks from fertilization, commonly called conception. The period of time required for full development of a fetus in utero is referred to as gestation (gestare = “to carry” or “to bear”).

Uteroplacental ischemia in early- and late-onset pre-eclampsia: a role for the fetus? Collectively, these observations suggest that there is a dose–response relationship between the magnitude of uteroplacental ischemia and the timing of onset of pre-eclampsia. A striking example of this is the development of pre-eclampsia before 20 weeks of gestation in patients with mole or partial mole.
