Prenatal development
- Germinal stage. Conception occurs when the female egg (ovum) is fertilized by a the male sperm.
- Embryonic stage. The embryonic stage begins after implantation and lasts until eight weeks after conception.
- Fetal stage.
- Congenital abnormalities.
- Maternal derived abnormalities.

What are the 3 major stages of prenatal development?
This union marks the beginning of the prenatal period, which in humans encompasses three distinct stages: (1) the pre-embryonic stage, the first two weeks of development, which is a period of cell division and initial differentiation (cell maturation), (2) the embryonic period, or period of organogenesis, which lasts …
What are the stages of pregnancy development?
It is divided into three stages, called trimesters: first trimester, second trimester, and third trimester. The fetus undergoes many changes throughout maturation.
What is the order of the stages of prenatal development quizlet?
Prenatal development proceeds through the germinal (first 2 weeks), embryonic (2 weeks to 2 months), and fetal stages (2 months to birth) as the zygote is differentiated into a human organism.
Which stage of prenatal development is the most critical?
The embryonic period is the most critical period of development because of the formation of internal and external structures.
Which is the correct sequence of development for a fertilized ovum?
Hence the correct answer is ‘C’ i.e, Zygote-morula-blastula-gastrula-embryo.
What is the order of the stages of prenatal development group of answer choices?
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.
What is the correct list of stages of prenatal development in order of progression?
There are three stages of prenatal development—germinal, embryonic, and fetal. Prenatal development is also organized into trimesters: the first trimester ends with the end of the embryonic stage, the second trimester ends at week 20, and the third trimester ends at birth.
What is the correct order of events in fertilization?
The stages of fertilization can be divided into four processes: 1) sperm preparation, 2) sperm-egg recognition and binding, 3) sperm-egg fusion and 4) fusion of sperm and egg pronuclei and activation of the zygote.
Which stage is most important in pregnancy?
The first trimester is the most crucial to your baby’s development. During this period, your baby’s body structure and organ systems develop. Most miscarriages and birth defects occur during this period.
What is the correct order of stages of prenatal development?
There are three stages of prenatal development: the conception stage, the embryonic stage, and the fetal stage. Each stage of prenatal development is carried out over the course of approximately 40 weeks, which is the average length of most pregnancies. The conception stage is the shortest, and the fetal stage is the longest.
A pregnancy is usually measured in 40 weeks of gestation, but many people prefer to measure it in months. The three main stages of development are conception, embryonic development and development of the fetus. Conception usually occurs around week two of the pregnancy.
What are the stages of fetal development?
Stages of fetal development includes the process of development of a baby from fertilization till delivery. There are three main stages of fetal development: The Germinal Stage, The Embryonic Period and The Fetal Period.
What is process starts at the embryonic period?
Fertilization. Fertilization is the union of the female gamete (egg) and the male gamete (spermatozoa).
