The secretion of the hormones in a normal human being is mainly based on negative feedback control, most of which involves the hypothalamic-pituitary axis that detects changes in the concentration of hormones secreted by peripheral endocrine glands. The hormones may also be secreted in response to changes in a controlled variable (Nussey & Whitehead 2001).
The following examples illustrate as to how hormones regulate physiological function.
The thyroid hormones, namely, thyroxine (T3) and tri-iodothyronine (T4) are secreted by the thyroid gland. They stimulate the oxygen consumption of most of the cells of the body, help in the regulation of lipid and carbohydrate metabolism, and are essential for normal growth and maturation. The thyroid hormones enter the cells after which T3 binds to the thyroid receptors in the nuclei. T4 binds, but not avidly. The thus formed hormone-receptor complex then binds to DNA via zinc fingers and affects the variety of different of different genes that code for enzymes which regulate cell function. The main physiological effect of thyroid hormones is calorigenic action (Ganong 2003). The hormones increase oxygen consumption of most of the tissues in the body except brain, testes, uterus, lymph nodes, spleen and anterior pituitary. The hormones also increase the metabolism of fatty acids. Due to increased calorigenic action, nitrogen excretion is increased and endogenous protein and fat stores are metabolized, which may lead to weight loss. The hormones also cause hepatic conversion of carotene to vitamin A. Other functions include an increase in cardiac output by direct action on the heart and also by activating heat dissipation mechanisms. The pulse pressure and heart rate are also increased, thus shortening circulation time. In the central nervous system, the thyroid hormones increase the responsiveness of the brain tissue to catecholamines, thus activating the reticular activating system. The hormones also affect brain development and reflexes. They increase the rate of absorption of carbohydrate from the gastrointestinal tract. ...Download file to see next pages Read More

The Process of Banking Regulation

...Banking Regulation Introduction The idea of banking regulation stems from systemic effects of banking operation in the market. Economic stability depends on principles that influence financial market players (Beck, 2011:50). The recession that hit UK and other parts of the world led to revaluation of macro prudential principles with an aim of curbing financial volatility. Critics argue that creating macro prudential principles would eliminate operation, which allow banks to act without evaluating the impact of the action they are yet to take. The financial crisis exposed failures of banks to control financial meltdown. The case pointed out that banks directed their interest at the expense of the common good of the financial markets...

...Hormones HORMONES Blood calcium levels must be maintained within a narrow range of 9-11 mg/100 ml. If the levels of blood calcium rise above the recommended level of 11 mg/100ml, the calcium levels lead to the release of calcitonin from the thyroid glands. This hormone causes calcium to be deposited within the bones, inhibiting the breakdown of bone through the activity of osteoclasts. In addition, the osteoblasts undergo stimulation to form more bone tissues. As the levels of calcitonin in the blood rise to particular levels, it leads to the inhibition of calcitonin production via negative feedback mechanism (Islam, 2012: p39). When calcium levels fall below 9mg/100 ml of blood, the parathyroid gland is stimulated to release...

Information Systems Development Process

When a project has an obvious objective to be attained and the effort is very small, common sense and attention to what the client wants can be a suitable alternative to more complicated and formal methods. However, when the software system becomes more complex, the objectives are multiplied and start to depend on different configurations and circumstances, it becomes imperative to structure the development effort to avoid software development that does not answer the clients need, or does not have the requisite level of quality, or becomes impossible to forecast in terms of time and budget – or a combination of any of the preceding.

In situations of complexity in software development, structure methods seek to im...

Physiological Factors While Dealing With Health Issues

The body’s metabolism includes all the physiological processes in the body. Enzymes serve as catalysts to biochemical reactions that form a part of metabolism. The two distinct chemical phases of metabolism are anabolism and catabolism. Anabolism consists of building up carbohydrates, proteins, fats and nucleic acids from simple molecules, through the use of energy. Anabolism is responsible for processes such as growth, repair, and reproduction. On the other hand, catabolism is the process by which large complex molecules are broken down into smaller, simple molecules, with the release of energy. Metabolic processes are carried out by the cell organelles, each organelle has a distinct and crucial function. Every animal cell...

Future Digital Design Process

As we shape up the interface between the designer and the virtual environment we are naturally going to produce a greater and far better outcome.
It will enable the end-user to be more creative and experimental and explore possibilities that were previously tedious or impossible. The design possibilities of virtuality will enhance the outlook of environments.
Now we can also term it according to the duration it can last. For any new thing, the duration is 10-30 years. If it lasts for 10 it would be popular as a tool another 10 and it would very well be a theory and if it survives all 30 years it will soon be defined as a revolution.
It was the end of the 20th century and the beginning of the 21st century that saw th...
