Germinal Stage Essay

Improved Essays
The germinal stage starts with fertilisation. When the egg is fertilised it is called a zygote. The most common is to be fertilised in the fallopian tube, then the zygote is moved along the fallopian tube toward the uterus. It is a long trip that can take up to a week, all the while on this journey the zygote is dividing and growing. Once the zygote has divided multiple times the zygote changes into a blastocyst. A combination of forty-six chromosomes determines the physical characteristics and the resulting mental life.
Pregnancy is typically broken into three periods, or trimesters, each of about three months.
I trimester-from the first day of the last menstrual period up to 12 weeks of pregnancy, II trimester-takes from 13 to 28 weeks of pregnancy and III trimester from 29 weeks of pregnancy until

In the third trimester the baby grows and prepares for coming into the world. Therefore lungs are well developed and fingernails and toenails have begun to grow. Baby will begin to practice breathing, strengthen bones and open eyes. At times babies born with a genetic, congenital syndrome like Turners syndrome, which is caused by total or partial absence of one of the X chromosomes in all cells of the body, or some part of them. According to Donaldson (2006) that syndrome occurs in 1 out of 2000 born girls The most important features that occur in people with Turner syndrome are: low growth, poorly marked female attributes and in most cases, infertility. One of the most important features is the low growth in nearly 100% of the cases.
The average growth achieved by women with Turner syndrome is 143 cm and is about 20 cm lower than the average increase of women in the population. Body proportions of patients are not valid: they have short stature, webbed neck, and the lower limbs shortened in relation to the length of the trunk. In approximately 23-40% of patients with Turner syndrome have congenital heart

    Germinal, embryonic, and fetal makes up the phases of the “prenatal” period. In the first phase, germinal stage, “the zygote begins to divide and grow in complexity during the first two weeks following conception” (Feldman, 2014). In the embryonic stage the zygote forms into an embryo and the ectoderm, endoderm, and mesoderm forms. The last phase is fetal and in this stage, the child begins to grow…

    Other interesting information I found today at work was: the average height of a woman with TS who is untreated is 4” 8’. Turner’s Syndrome is not preventable or curable, but there are treatments like the ones I stated above. Another interesting fact is that most women with TS aren’t able to have children because they are missing one of the X chromosomes.…

Turner syndrome affects "1 in 2,500 every newborn girl," in the U.S. Turner syndrome is when a female has one working X-chromosome and one is altered or missing. The many symptoms include short stature, webbed neck and lymphedema, which is swelling of the hands and feet. To find out if you or a female you know has turner syndrome testing includes a lab test of your blood. Some people with turner syndrome can be diagnosed before they are even born but most are not diagnosed until as late as ages 5 to 10.…

    The endocrine system is a collection of glands that produce specific hormones. These hormones are released into the blood stream to help regulate the metabolism, growth and development, tissue function, sexual function, reproduction, sleep, mood and other functions. When the endocrine system malfunctions it hinders the release of these hormones into the blood stream this ultimately affects the balance of hormones, leading to an endocrine disorder. Endocrine disorders are grouped into two basic categories; hormone imbalance, when the gland produces too much or too little of an endocrine hormone or the development of lesions in the endocrine system, which may or may not affect hormone levels. There are many different types of endocrine…

    Edwards' syndrome, also known as Trisomy 18 is considered a chromosomal condition where there are abnormalities in certain parts of the body. People with Trisomy 18, often have slow growth in the wound (intrauterine growth retardation). These newborns usually have heart defects and other defects throughout the child’s body. This also includes a small shaped head, a small mouth and jaw, and sometimes overlapping fingers and small hands. Children with Trisomy 18 usually die within their first month, or before birth.…

    The pre-embryonic period is initiated after the ovum within the female becomes fertilized, forming a zygote, and travels to the uterus for implantation. This process of transfer takes roughly a week to occur and the cells rapidly divide forming a blastocyst. The blastocyst consists of an inner cell mass, called the embryoblast, and an outer cell mass, called the trophoblast. After the implantation of the blastocyst the embryoblast forms two layers of cells, known as the hypoblast and epiblast. By the end of the pre-embryonic period cavities have formed and the connecting stalk, which will eventually become the umbilical cord, is also present.…

    Down Syndrome affects physical growth, facial characteristics, and intellect. Also known as Trisomy 21, it is a genetic mutation in which a person is born with an extra chromosome. These chromosomes are rod-like structures where genetic materials are stored and grouped. The nucleus of each cell in the human body contains 23 chromosomes, half, being inherited from each parent. The added chromosome changes the systematic development, affecting not only physical traits but mental as well.…

    While implantation occurs, blastocyst is being concerted into gastrula, in which three germ layers from and embryonic membranes develop. The beginning is when the inner cell mass differs into two layers which are the epiblast and the hypoblast. Both of these cells form four embryonic membranes which are the amnion, the yolk sac, allantois, the umbilical cord, and the chorion. The amnion provides a buoyant environment which protects the embryo from physical trauma and helps maintain a constant temperature. The yolk sac provides nutrition for the embryo, produces early blood cells and vessels, and is a source of germ cell that migrate to the embryo to seed the gonads.…

    Edwards syndrome also known as trisomy 18 is a condition of severe growth development that causes abnormalities in some part of the body and also affetcs some of the organs in the body that develop before birth. Trisomy 18 is very common especially among girls. Babies with trisomy 18 syndrome will grow slowly in the womb and will have a low birthweight when they are born. This disorder is genetic and it happens when there are abnormalities within the 46 chromosomes. During a pregnancy, 23 pairs of chromosomes from each parents are supposed to be inherited to the baby, but with trisomy 18, there are more chromosomes being passed on which cause disruption of a normal fetus development.…

    The DNA of an individual carries their genetic information. This information is contained in the nucleus, coiled to make chromosomes – 23 pairs in total. Each chromosome codes for a specific trait, and contains genes – the code for proteins. Chromosomes consist of two sister chromatids joint by a centromere, with the regions above the centromere called the ‘p’ arms and the region below called the ‘q’ arms (see figure 1). 22q11 deletion syndrome (22q11DS) refers to the deletion of a section of the q arm of the 22nd chromosome at position 11.…
