Contextualizing the Reality of Teratology Teratology is the study of physical abnormalities. Such abnormalities occur naturally through physiological means, although the environment and environmental factors -- which can impact an organism's biology and physiology -- plays a part in this study as well. Typically, teratology is concerned with physical deformities in organisms. Initially, such deformities pertained to people, although this particular discipline has evolved to include virtually any sort of living organism. Moreover, teratology is considered with the manifestation and fostering of physical abnormalities throughout the various stages of life. Typically, these deformities begin during the process that occurs immediately after conception in which organisms are developing. However, it can also extend through periods of puberty, and can encompass virtually any stage of life prior to death. It is critical to note that when discussing the natural origin of the deformities that are a part of this science, the environment can play a considerable part in the creation of these abnormalities. For instance, waste, toxicities, radiation etc. can drastically change one's environment, and thus make creatures that are part of that environment procreate with a number of differences distinct from those creatures that are procreating in a different sort of environment. Teratology is concerned with all of...
The most capital of these principles is the tenet that the likelihood of abnormality depends on the type of conception and the way in which such a conception interacts with the environment (Aston, 2014). The second principle relates to the developmental stage of an organism being conceived and its relationship to any transformative agents within the environment. Some points in the development stage are more vulnerability to agents than others, quite simply. The third principle is that agents of teratology produce specific effects on developing organisms and on certain parts (such as tissues) in order to engender the physical abnormality process. The fourth principle is that there are a number of different factors associated with the exposure of an organism to agents that account for teratology. These include the point of contact between the two, the nature of that contact, length of time, etc. Once that agent has interacted with an organism so that deformation occurs, there are only four possible outcomes: the end of life, physical deformity, retarded growth, and functional problems (Aston, 2014). Lastly, the greater the influence (both in degree, quantity, and instance of occurrence) of agents…
Teratology Define the term Teratology Teratology refers to the study of abnormal fetal growth. Teratogenic prenatal exposures arise from: infectious agents, chemical and drug agents, metabolic or maternal causes (such as phenylketonuria and diabetes), and physical agents (such as heat, ionizing radiation, and mechanical factors) (Jelinek, 2005). Inbred abnormalities occur commonly, with 2-3% babies, both live and stillborn, as well as aborted fetuses having structural abnormalities. Furthermore, about 10% of infants have
Teratology is the scientific study of causes and mechanisms of malformation during the human development. Fetal diseases, mechanical effects and retarded development of the embryo and the fetus are some of the causes of CDDs (congenital developmental disorders) according to various studies. Both mystical and scientific theories were developed in the past to explain the origin of Teratology; some theories stating that it originated from the position of the stars,
Fetal Alcohol Syndrome Special Education About the Child Pietro is a 7-year-old boy. His biological parents are Argentine and Colombian. He was born approximately six weeks prematurely because of his mother's consumption of alcohol throughout the duration of her pregnancy. According to medical reports, his mother did not consume heavy quantities of alcohol, but she did consume nominal amounts on a regular basis, such as one to three times a week, nearly
Teratogens and Fetal Development Teratogens can be described as agents that contribute to fetal injury and birth defects or an abnormality because of fetal exposure during pregnancy. Some of these agents that lead to fetal injury or birth defects include chemicals, environmental contaminants, infections, and drugs. These agents tend to result in such abnormality in fetal development when a woman is exposed to them during the term of the pregnancy. The
This would clearly be preferable to performing surgery, but may be more applicable in cases of type B than type a polydactyly. Of a total of 21 cases which were examined, this procedure resulted in a slight complication in only one case, where the digit had to be removed surgically due to failure of removal by suture ligation. The only real side effect of this simple treatment is that
