Human development can be described as the way a human body forms as the process of life begins. Along this process different kinds of mutations and diseases can occur, some may be natural and others self-afflicted (Sigelman & Rider). The area of human development I am focusing on is the time between conception and birth of a fetus, this is especially important because it is the making of a life (Sigelman & Rider). This time frame of nine months is called gestation. It is divided into three equal trimesters (Holt, Rinehart & Winston) This period of one’s life span occurs the fastest and has one of the most important environments (Sigelman & Rider). Throughout the life of an embryo/fetus before it is born as a grown baby, there are several stages that their bodies have to go through. Cells that are formed earlier and have not been specialized yet can be identify as stem cells. When the spiral cord begins to form the embryo is coming into three weeks of growth and begins to have a system to support its body (Sigelman & Rider). This time is very vulnerable for the development of the baby’s organs (Holt, Rinehart & Winston). Five to six weeks the torso, head, and limbs and begun to form. Also the system that takes shape …show more content…
The baby’s sex on the other hand is determined at fertilization. If an X chromosome is present the baby is a girl. If a Y chromosome is present the baby’s a boy. Over the course of 20 weeks the way a baby grows has to go almost seamlessly to form a healthy baby with 20/20 vision and no deformities (Website1). A disruption to the fetus form exposure to diseases or toxins can result in birth defects and developmental problems. There is currently no way to repair brain defects from early development. That being said, a mother is one of the main controlling factors due to the risks she decides to take after the time of conception (Website
1.1 Describe, in-depth, stages of development from conception to birth in groups of 4 weeks i.e. 0-4, 4-8, 8-12...36-40 weeks.
In this essay I will be going to consider the lifespan development process and describe the following changes in an infant from content supported in my text. Infants are one of the most amazing transformations I think the world sees. To think we all came from infancy and developed into grown adults who do amazing things everyday. I’ll be talking about the physical change in an infant,as well as the mental changes they experience,and the sensory changes they go through that we all went through and eventually brought us to adulthood.
say that the beginning of life should be at least measured by the beginning of brain life. By six weeks, an unborn baby's brain waves can be recorded by an electroencephalogram (EEG).10 Between six and seven weeks, the unborn baby will respond to external stimuli, such as touching his or her face.11 While many people believe that a fetus is merely a mass of flesh, and is not nearly as complex as a human, this is completely untrue. By eight weeks, all of the body systems are present, and by eleven weeks, still i! n the first trimester, all of those body systems are
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 scientific study of how humans developed did not begin until the 1800s in Europe. Until that time, people relied on religious explanations of how humans came into existence. Starting in the 1500s a scientific revolution began to sweep Europe. Thinkers started using scientific methods and experiments to try to better understand the world and the creatures living in it. Eventually these methods were turned to the question of human origins” (The Nature Of Human Origins, 1). Earth made it possible for species to change over time because Ancient Earth provides ability to plenty of time.The Homo Sapien a is very complex creature. The species started off very simple by living in caves and surviving with little food and then later evolved into a species that were able to do many more complex things. The first species was Sahelanthropus tchadensis They were one of the most simple humans in that time period and on. They had very small skulls compared to Homo Sapiens today and their motor skills were just the same. We have evolved and changed for the better both mentally and physically. The Evolution of Homo Sapiens started off simple, such as the Neanderthals, and now we are the most advanced species to ever walk the planet so far.
All the fetus’ nutrients and oxygen come from the mother’s blood. During the fourth month of development, bone replaces the fetus’s cartilage and may begin to hear sound. The remaining part of this section showed the developmental process in each stage of development.
In this essay I intend to discuss two psychological theories of development; The psychodynamic approach and the behavioural approach. In order to do this, I will outline each theory and explain how it accounts for psychological development, health and behaviour of the individual. In addition to this, I will explain how an understanding of these theories relates to care and would help a care professional to support an individual in a care setting.
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...
The prenatal period takes place in the first two weeks of conception. Heredity and environmental influences (which are often negative) are also developed during this stage. At this stage the organism is more susceptible to these influences, than during any other period. Infancy is the next stage, various changes start to occur and attachments start to form. Coordination, sensory and motor skills start to develop, as well as the expression of feelings and emotions.
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
From preschool into early elementary school, children have begun to develop their gross motor skills. They have developed a “mature pattern of walking” and are ready to test their physical abilities to the limits. Also fine motor skills have begun to develop, however more slowly. Along with motor skills children are developing their visual, tactile, and kinesthetic senses. A child’s sensory skills are helpful in learning language.
Developmental Psychology is an area which studies how we as humans change over the period of our life span. The majority of the focus is broken into three categories: cognitive, physical and social change. The creation of who we are today comes down to the everlasting debate of nature versus nurture. This ongoing debate of what makes us who we are and which one is the driving force in development may be so simple that it’s complex. Rather than it being a conflict of nature “versus” nurture, it is very well possible both play an equal part in the development of us as humans. In the beginning, we start off as single cell in the form of a zygote. In that moment, where the DNA begin to form and the first seconds of life take place, the zygote is already experiencing interaction with the womb. In the process of determining why we are who are it is better to look more at the interactions of nature and nurture, analyzing how both have shaped us.
