The Transformation Of Human Development

Development of the embryo into a fetus throughout pregnancy consists of three main periods of development, made up of several weeks of development between each one; these are referred to commonly and by medical professionals as the first, second, and third trimesters of pregnancy. Following conception, the embryonic stage of prenatal development begins through the fifth week of pregnancy in which major structures begin to form. At this stage, the cells of the body begin to differentiate into cells that are specialized in unique functions such as blood, kidney, and nerve cells for their corresponding organ systems (Hill, 2016). According to Sacks

Shortly after an egg is fertilized stem cells begin to form. These cells are programmed to form every organ and tissue in the body as the baby develops.

Those stages are the Germinal stage, the Embryonic stage, and the Fetal stage. The Germinal Stage is the first stage and it is a two-week period that happens after the sperm and egg cell join together to form a zygote. This process is called conception. After conception, the zygote begins to divide. This turns into into a ball of cells that moves beside the fallopian tube. This travels all the way to the uterus. This process is called implantation and it happens when the cells is placed in the wall of the uterus. This process takes about a week to complete. After the two weeks, the Embryonic stage takes place next. The embryonic stage takes two to eight weeks right after conception. At this point in the process, the ball of cells is now an embryo. In this stage, all the major organs form. The last stage of prenatal development is the Fetal stage. This last eight weeks after conception up to birth. One of the first things to take place is the sex organs begin to form. Next, the bones form, muscles form, and the fetus begins to move. The organ systems also begin to develop and the brain’s size grows. One of the last things to work independently is the respiratory and digestive

Contained in the human body there are more than 220 different cell types being derived from a group of cells called embryonic stem cells. Being located in what is known as the inner cell mass of a blastocyst which is a young embryo about four to five days old. The uniqueness of these cells and what defines them is that they are pluripotent, meaning they are able to differentiate into any 3 germ layers. These layers include the endoderm, mesoderm, and ectoderm. Being able to

The first premise states that a fetus is an early stage in becoming a human. It all starts with conception. When the sperm meets the egg, the combination is called a zygote. The zygote contains all of the genetic information (DNA) needed to become a baby. Half the DNA comes from the mother's egg and half from the father's sperm. The zygote then travels down the fallopian tube, in which, it forms a ball of cells called a blastocyst. The blastocyst is composed of an inner group of cells with an outer shell. The inner group of cells will become the embryo which is what will develop into a fetus. The fetus is the stage of development up until birth. Of course, after birth you have an infant, then a toddler, then a preschooler, then middle childhood, teenagers, and lastly adulthood. All of which came to be from a mere zygote.

One type of Stem cells is embryonic stem cells. 5 or 7 days into a fertilization process, the egg divides rapidly and produces a ball of cells called a blastocyst in which all the cells are alike. Gradually, after this stage, the cells start differentiating. Differentiation involves the expression of some genes from the organism’s genuine in the cell, but not others. This process assigns each cell specific purposes and once differentiation takes place, it cannot be reversed in most cases. Cells in the blastocyst have the potential to turn into almost any cell types: they are said to be pluripotent and are known as embryonic stem cells. These cells are isolated from the inner cell mass of blastocysts of pre – implantation stage embryos. The properties of embryonic stem cells are still kept.

After reading this article anyone could understand when human life begins. A reader would also have comprehension of why these facts are not publicized, why embryos don’t always continue to full-term pregnancy and why scientists will not speak out about the recent discoveries. This article is very useful to anyone who wants to learn the scientific side of when the human life begins. The article is from a reliable source and will give an individual the background knowledge needed to argue when life begins. Overall, this article is a great choice to use just for enjoyment of to gain

Introduction: When we are living in the human society, the issue of human developmental has been

During the earliest stages of the development of the embryo, its cells are entirely undifferentiated. When a cell has not yet discovered its operation in an organism, it is classified as a stem cell. The two major varieties of stem cells have been distinguished as pluripotent and totipotent. An example of a totipotent cell is an egg that has been fertilized by a sperm cell, and is a single cell egg. This cell now has the ability to develop into any and every human cell. “The first few cell divisions in embryonic development produce more totipotent cells. After four days of embryonic cell division, the cells begin to specialize into pluripotent stem cells” (Biomed Brown Edu). Pluripotent cells however, are not as adaptable. Nicknamed the “master cell”, pluripotent cells have the ability to produce cells from the three basic body layers, enabling the possibility for them to create all cells or tissues that the body may need to heal (Children’s Hospital Organisation).

The method in which children come into their development is a very significant procedure that every person should be able to recognize. Children are not all the same so their development is not the same either. In fact, most children cannot even be treated the same when in regards to their development. To get a better understanding that involves the way children and teenagers grow a person would need to really recognize and comprehend the model of human development. This essay will emphasis on the Bio ecological Model of Human development; the diverse systems that are within human development and also how each of the systems are different.

Prenatal development is a very fragile phase of fetal development that can be affect by environmental factors and maternal factors. Prenatal development is the process in which a human fetus develops during pregnancy. The development of a new life is an exciting time for most people and this essay will discuss the process in which that new life is created. It will also discuss the things that could be harmful to the development of that new life during its prenatal development term such as environmental factors and maternal factors. Both of these things are important in the field of early child development because these things could cause harm to the development of systems in the body that are important for a child’s body to function properly and for their development to flourish. Prenatal development happens in three stages. The first stage is the germinal stage it happens two weeks after conception occurs. Conception is the process in which the egg from the mom and the sperm from the dad come into contact. The zygote which is a cell formed by the union of the male sperm and the female egg separates after conception, and this leads to the formation of balls that move along the mother fallopian tubes to her uterus. It is at the point that the placenta is formed, which plays a significant role in development throughout pregnancy. It acts as an active transport of blood supply and nutrients between the mom and fetus and helps with fetal growth. For this reason it is important

In Experience Human Development, Papalia and Martorell define young adulthood as ages twenty through forty, although the idea of young adulthood is more a social construct than an actual age range. Upon entering this phase, individuals have reached their full-grown physical stature. In fact, adults are considered to be at their physical peak during this phase of life with most young adults claiming to be in good to excellent physical health. However, the modern lifestyle has started to affect this statistic, with more and more young people reporting health-related risks and concerns due to a poor diet and a decrease in physical activities (Papalia & Martorell. 2015).

Surveys that have been conducted in the current times have revealed that there are many adults that are returning to their parents at home. It’s not the first time that this pattern is being experienced it have happened in the past and it have always been accompanied with financial problems, it’s no different even now (Adler, 2001). It occurs when the economy is in real struggle this makes it harder for the young men and women in the society to find their financial independence. Jeffrey Arnett a psychologist came up with a suggestion that in these modern times the stages of development are increasing (Mitchell, B 2006). He said that there is a new type of the classification of the ages known as the emerging adults; this is what bridges the gap between the adulthood and the adolescents. As per the theory it is believed that people while at their 20s undergo a stage of development which is different from the stage of adulthood (Morton, R 2013). This could serve as a good explanation why most of the young adults remain in their parents’ home completely.

There are three foundations of human development. The foundations are the biological development, psychological development, and social development. The concept of human diversity and cultural competences demonstrates how different people can be. General systems theory and social order are connected in some way.

In this paper I will be explaining the 12 stages of life. Such as prebirth, birth, infancy,
