There are three major stages of the prenatal development process. The Germinal Stage, Embryonic Stage, and the Fetal Stage. While most people think that the process of development starts after a baby is born, the prenatal period is very crucial to the overall development of a child. During the prenatal period very major things can go wrong, such as mutations or chromosomal abnormalities, which can cause downsyndrome and other diseases. The process of development begins at the very moment of conception. In this essay I hope to achieve a goal of successfully detailing and describing the three stages of prenatal development FIRST STAGE (GERMINAL PERIOD) During the germinal period prenatal development begins at the moment of conception. …show more content…
This stage begins around the second week and lasts until eight weeks after conception. As the cells divide and start to develop their own functions a process known as gastrulation takes place. Three germ layers form because of this process and they are known as the ectoderm, mesoderm, and endoderm. The ectoderm, which is the outer layer is responsible for forming the nervous system, skin, hair, nails, teeth, nose,mouth, anus, and other tissues. The mesoderm, which is the middle layer is responsible for forming the skeleton, muscles, circulatory and excretory systems. Finally the endoderm, the inner layer, is responsible for developing the lungs, pancreas,liver, and digestive tract. At around the third week major organs such as the brain, heart, and spinal cord are forming. Week four, five, and six other body parts start to form. Specifically around week four is when the baby’s heart will start to beat. Week six and seven things such as hair follicles and eyelids are forming. In these two weeks continual development of the brain and heart occur. Around week eight, facial features are becoming noticeable and most internal organs are well developed. Sex organs also start to form around week …show more content…
The three stages Germinal, Embryonic, and Fetal stages all play an important role. Each stage the fetus starts to form or develop something new, which may or may not be crucial to a person’s life. Overall I hope to have fulfilled the accurate description of the fetus throughout the three stages of
In conclusion, the first stage of giving birth consists of contractions that will help get the baby's head into the birth canal and get ready for delivery, along with the cervix thinning out and dilation increasing. During the second stage, you will begin to push the baby out. As the tissue starts to stretch, you might experience “the ring of fire”. Shortly after the stretch, the baby's head will be out and then its body. The final stage is quick and almost effortless.
With the increased rate of integrating In Vitro Fertilization (IVF), there has been a steep inclination within the associated needs of specifications. Observably, the development of babies using scientific measures was initially formulated and specified for developing the diverse range of development associated with the same (Turriziani, 2014). However, these developments are noted to be creating an adverse impact on the natural course of events and subsequently, resulting with an adverse impact on the natural process of the development of babies. The initial integrations within the system of IVF for developing babies have further been initiated with the effective use of science to develop a healthy baby. Hence, the use of such progressions can be argued as not hampering the ethical needs associated with the same. Conversely, the initial progression within the same and the changes in the use of such practices are identified as unethical, as it has been acting as a threat in the natural course of development of embryos and altering the natural course of events, suspected to be imposing significant influence on infant mortality (Turriziani,

Based on my knowledge about prenatal development and childbirth I expected the women to answer the way they did. Development happens rapidly during the prenatal period, which is the time between conception and birth. Prenatal development is normally divided into three stages: the germinal stage, the embryonic stage, and the fetal stage.
The five environmental influences that I would use to publicize in a campaign to promote healthy prenatal development would be: the effects of the use of alcohol, tobacco, drugs, some medications, and diseases. These environmental influences are the most common problems that women who are pregnant face today. Most lack the knowledge of how and why these influences are harmful to their unborn child, and if needed how they can seek treatment.

There are two different ways to break down the prenatal time period: by trimester or by periods. The first period is called the germinal period. This time frame consists of the first fourteen days of the baby’s development starting with conception. During these two weeks, the fertilized egg makes it’s way into the uterus for implantation in the lining of the uterus. The next period, the embryonic period starts here. The embryonic period lasts the third through the eighth week of pregnancy. During this time period, according to Kathleen Stassen Burger, Author of The Developing Person: Through Childhood and Adolescence, “…the formless mass of cells becomes a distinct being-not yet recognizably human, but worthy of a new name, embryo” (Burg...
The process of human development is very complex. It is a continual process, providing gradual development for the fetus. Some of the most important factors to fetal development such as blood flow, heart beats, muscle development, and brain activity can all be determined within the first seven weeks of pregnancy (Baby Developme...
When a child is born it brings a parent much joy and excitement. When the baby enters the world they are helpless humans that depend on others to survive. A baby will be so dependent on its caregiver to learn and develop. Milestones are things that some children are doing at that age, however; not all children will meet those milestones. Children are individuals and should be looked at as such. The author of a news story from News Bank Access World News states, “Nothing replaces contacting your pediatrician if you have any questions or concerns, but the following may help you to identify and nurture specific developmental milestones” (Diana, 2011).
The first period, the germinal period, is classified as the first two weeks after conception, that is identified by how fast cells divide and differentiate. During this phase a zygote duplicates. After that differentiation begins, this is where early cells take on their own characteristics and move to their predetermined locations. Once that is complete a cell mass will then become either a placenta or a nucleus, together they will become the embryo. The second period is called the embryonic period. This. Is this stage of development that occurs during the third to the eighth week after conception. During this phase, the basic structural forms of the baby's body appear. At the beginning of this period a line (the primitive streak) appears turning into the neural tube, and eventually turning into the central nervous system. in the fourth week eyes, ears, nose, mouth, and minuscule blood vessels (becoming the heart) begin to appear. Between the fifth week and the end of the embryonic period arms, legs, hands, feet, fingers, and toes appear. The final stage, the
As children grow towards adolescence they go through many stages of development. Child development refers to the stages of physical, cognitive, emotional, social, and language growth that occurs from the birth to beginning of adulthood. All aspects of a child's development may be affected by many different factors, including a poor learning environment, lack of social interaction, cultural background differences, abuse, and loss of a parent. All of the before mentioned examples can affect the child's maturation, "a biological growth process that enables orderly changes in behavior, relatively uninfluenced by experience" (Myers 172). Children grow and mature at very different rates, some faster than others, which is why it is necessary to understand the importance of the different types of child development. Though all parts of child development are important, it is probably language learning that is most important to a child's development as a whole.
Fertilization occurs when the sperm from the male and the ovum from the female combine to create a zygote. The zygote will then go through a gestational period which consists of three different stages. The first stage is the germinal stage and it starts from conception and ends at two weeks, during this stage the zygote divides and becomes much more complex and then implants into the uterine wall where it will then go on to the second stage. The second stage is the embryonic stage, this stage starts at two weeks and ends at eight weeks. During the embryonic stage the zygote has become an embryo and the organs and major body systems form and develop very rapidly. This is one of the most critical periods for physical development, the embryo is very sensitive to many different types of influences. The third and final stage of the gestational period is the fetal stage, this stage starts at eight weeks and ends at birth. During this stage the fetus grows approximately twenty times its previous length and the organs and body systems continue to develop becoming more complex and becomes ready for survival outside of the womb. Children grow the fastest during the first three years of their life, and they will never grow this rapidly again. As the child grows the child will go through various stages of physical development such as puberty and sexual maturity. After the first few
The course of prenatal development normally initiates with fertilization and ends with birth, lasting 38 to 40 weeks of gestation. It can be separated into three phases: germinal, embryonic, and fetal. The first two weeks after conception the germinal stage of prenatal development takes place. During this stage, a group of cells,
In this report I will be discussing the development issues about prenatal development, and the newborn. Developmental psychology is basically a psychology study that focuses on the cognitive, physical, and social change throughout our life span. In prenatal development we learn about nature and nurture, continuity and stages, and stability and change. Prenatal Development is the process in which babies develop from one single cell after making a baby into an Embryo and later on a fetus . An Embryo is the process of a human organism for about approximately 2 weeks after the fertilization though the second month.
This process is called conception, the female is now officially two weeks pregnant and the fertilized egg is called a zygote. Let’s move on to pregnancy. Pregnancy is a state in which a woman carries a fertilized egg inside her body, it usually lasts up to 40 weeks, and it is divided into three trimesters, each lasting three months. The first month. The embryo is about a third of an inch long. The head, trunk, and the beginnings of the arms and legs have started to develop. By this month, the embryo starts to receive nutrients and releases waste through the umbilical cord and placenta. The heart also starts to beat. The second month. The heart is now pumping and the nervous system, including the brain and the spinal cord begins to develop. The fetus is 1 in 2.5cm now and has developed cartilage skeleton. The arms, legs, facial features and other major organs begin to appear. The third month. The fetus has grown up to 4 in 10cm and weighs a little more than an ounce. The major blood vessels are almost completed and the face starts to show up more. The kidneys and the 4 chambers of the heart are now complete. The fourth month. The fetus is now 4 oz of 112g and can kick and swallow. The
