Download file to see previous pages A natural process in which certain characteristics are transmitted from parents to off springs. The transmission of these characteristics from parents to off springs depends on the genetic makeup of parents (Cummings,8). Any abnormality in the genetic machinery will lead to abnormal products and thus abnormal characteristics. Regarding the mode, in case of abnormality in the genetic machinery in the parents, the transmission of defeat is subject to abnormality in parents.
Autosomal includes autosomal dominant and autosomal recessive. The second is dominant and recessive. Further these patterns of inheritance depends on the defective genetic material transmission through sex chromosomes. Autosomal chromosomes (each individual has 23 pair chromosomes, 22 pairs being autosomal and 1 pair of sex chromosome (Russo,579).
Trineucleotide repeat disorders: Most of these genetic disorders present in young and middle age individuals. Prognosis of individuals with genetic disease on the basis of age factor. The question that genetic diseases in young population are more lethal than being in elderly population, the aggressiveness of a genetic disease depends on the following factors,which will be even explained with examples. First is mode of inheritance. Second is age. Third is severity and nature of individual genetic disease. Fourth is Phenomenon of anticipation. Fifth is complications developed as a result of genetic diseases.
Thalassemia, a blood disorder, in which there is a genetic defect and leads to abnormal gene formation resulting in an abnormal beta-Globin protein, a component of the oxygen carrying molecule hemoglobin. Depending on the number of genetic mutations, the corresponding number of globin chains are being abnormal, resulting in abnormal hemoglobin formation, ranging from a single globin gene ...Download file to see next pagesRead More

...?Introduction: Cell is the basic structural and functional unit of the body and each cell is adapted to work ideally under certain environmental conditions. Therefore, cell as a unit and all the systems of body, function in order to preserve a reasonably constant internal environment or a state of equilibrium which is called homeostasis. The concept of homeostasis was first given by Claude Bernard in 1860s who credited the stability of milieu interieur to body’s capability to sustain stable internal environment and making basic alterations to achieve that state of stability (Appenzeller, Vinken and Bruyn, 1999). The term homeostasis was first used by Walter Cannon in 1932 to illustrate the “maintenance of body’s dynamic constancy... ”....

...?Homeostasis Introduction Nature has bestowed our planet with several ecosystems. These ecosystems are driven and controlled by the wide variety of plant, animal, and microbial life present within these systems. In this context, the balance of the ecosystems is maintained by these various life forms (Naeem et al, 1999). What do we mean by maintaining control of the balance of the ecosystem? Ecosystems are fragile making it essential for a balance of the various life forms. For instance, rodents may multiply due to the influence of factors beneficial to their multiplication with the potential for upsetting the balance of the ecosystem. Yet, their numbers are kept in check by a similar increase in their predators like,...

...Homeostasis Introduction: Homeostasis is, in fact, maintenance of an environment. In medical science, it is an ability of human body to keep internal environment at or around (with very narrow range) a level in which various systems of the body can perform smoothly. Through this property human body responds to different types of disturbances of homeostasis efficiently so that health is maintained. Thus internal environment of the body is maintained by a close surveillance system and timely response to any change which may affect homeostasis. This adjustment of physiological systems within the body is called homeostatic regulation (Wikiepedia 2007). As body needs to...

...HOMEOSTATIS I. WHAT IS HOMEOSTASIS Homeostasis is the regulation of the physiological processes of organisms to preserve their internal equilibrium as a reaction to changes in the external environment (Homeostastis, Excretion and the Kidneys). Stability is the aim of Homeostasis as it controls internal reactions against external changes by adjusting its processes to maintain balance. For the purpose of this paper, we will be limiting the reference to humans as organisms. II. THE PROCESS OF EXCRETION The search and removal of wastes inside the body which it produces, is called the process of excretion (Poison Protection). The major organs of excretion are the kidneys for urine...

...Homeostasis Homeo is derived from Greek and is a word that indicates similarity or “same kind”. Homeostasis in bodily processes refers to activities that enable the body to stay in a state of equilibrium. Theories of homeostasis draw from the idea of the being as an open structure. In the middle of the twentieth century, a biophysical hypothesis mainly based on self-structure and Dynamic Systems hypothesis permitted individuals to come up to the quantity and quality analysis of the structured difficulty that makes up living systems (Ikegami and Suzuki, pp.389). This mixture of theoretical structure and a more advanced experimental system discovered that feedback management of steady...

...Homeostasis and Negative Feedback by :________________ [Department Homeostasis Homeostasis is the ability of a body to maintain conditions of equilibrium within its internal environment when there are changes in the external environment (Paul, 2013). Keeping this definition in mind, we will now analyze the effects of running on homeostatic processes. When we run for a period of time, there are various changes that occur. Some of these include: Increased oxygen consumption Increased oxygen delivery Rise in Body Temperature Since muscle cells need a steady supply of energy to keep the contracting and relaxing during exercise, the rate at which energy is consumed increases due to the...

...MAINTENANCE OF BLOOD SUGAR LEVELS Introduction The human body consists of millions of cells that require themaintenance of the conditions in their environment, at a state that is almost constant to ensure proper functioning. The processes that maintain these conditions describe homeostasis processes ( 2013). Blood sugar level refers to the amount of glucose level that is present in the blood to be used as fuel by the cells to provide energy necessary for the processes of the cell. The blood sugar levels may vary at different times. Maintenance of blood glucose levels The process of blood sugar regulation involves the hormones insulin and glucagon ( 2013). These are released at...

...Homeostasis Human physiology entails the scientific investigation into the nature of biochemical, physical and mechanical functioning of humans, their cells and organs, and how they keep the human body alive (Giannetti, Burton & Donovan 343). Physiology has its principle focus at the systems within systems as well as organ level and how physical activity influences them. In the context of athletic training, exercise can be viewed as the training or conditioning performed in respect to sporting objectives. Further, athletic training may aim at improving physical fitness, general health or to augment ongoing treatment, to restructure the effects of illness or disease on the body and for physical therapy. This paper will...

...Topic: Homeostasis Homeostasis is the maintenance of the internal environment of the body according to the changes in the external environment and as per the needs of our body. The maintenance of body’s internal environment is vital for the survival and normal functioning. Homeostatic mechanism works when different organs and glands of the body controlled by nervous system detect a change in the external environment and in response make changes in the body to adapt to the new external environment for survival of the body. The body achieves homeostasis by altering/changing the internal environment rather than keeping it to a static state because a static internal environment cannot...

...Homeostasis Lecturer’s Homeostasis in the human body The body’s homeostasis is the process by which the body maintains a favorable stable internal environment to be able to function appropriately. The hypothalamus located in the brain plays a great role in helping the body maintain homeostasis as it is linked to a group of neurons that form a primary link to the endocrine and nervous system. This small body part involved in many homeostasis activities such as regulating the body temperature, thirst, hunger, heart rate as well as the blood pressure. However, maintaining the constant equilibrium of body systems such as temperature requires the body to make...
