Essay On Human Growth Hormone
explanatory Essay
559 words
Human growth hormone has been identified for its effect on the growth processes in the human body. Growth hormone as the name suggests itself is primarily concerned with the ideal height of an individual. Now, how does HGH actually play in the growth process?
HGH is a protein hormone that has a 190 amino acids sequence. It is a major product of the anterior pituitary gland and is produced by cells called somatotrophs. Aside from the HGH, there are other hormones that are involved in the growth process thus making it more complex than other processes. In general, the growth hormone excites tissues like the liver to secrete Insulin like Growth Factor (IGF-1). This product then stimulates the propagation of cartilage cells which results in bone

The other, dual effectors theory, asserts that the growth hormone plays a straight role at the growth plate where it supports the differentiation of different cells while stimulating the fusion and secretion of IGF-1.
The growth hormone also plays a role in maintaining a healthy bone density to decrease the possibility of osteoporosis and other bone diseases. Although the growth hormone is the major player in the growth process of the human body, there are still other body hormones that help in the growth process. These hormones interact with other glands and substances to aid the growth hormone. Examples of these hormones are the thyroid hormones, the sex hormones and the follicle stimulating hormone.
The growth hormone continues to be secreted even as human bones have closed and have stopped growing. The reason why children grow at ages before and during puberty is that the HGH is produced at peak levels during those years of an individual. Growth hormones are also secreted at the onset of sleep so there is a bit of truth when elders say that children should sleep earlier to grow taller. HGH secretion lessens when a person enters his middle ages. Along with the decrease in secretion of HGH come the symptoms of aging as people grow old. Because HGH contributes in bone growth and density, the status of the

It is commonly prescribed by doctors in situations where one has turner’s syndrome, prader-willis syndrome, chronic kidney insufficiency, low hormones, or if they are naturally shorter than those their age (Dunkin). HGH is used for serious disorders, yet doctors, the FDA and others think that one being short is serious enough to have HGH prescribed. Worse yet, usually those that are short and are given the HGH option do not believe that being short should be grounds for one to risk something that could cause cancerous tumors. If one is short enough to have the option of HGH then they should have just as many protections as a minority or one with dwarfism would. However, Paul Steven Miller, who is a dwarf and stands at 4’5”, does not believe that. He says that dwarfs go through more discrimination than those who are short and well below average

745 wordsRead More - Hypothalamus Roleexplanatory essayThe function of the growth hormone –releasing hormone is to stimulate the pituitary gland to produce and release the growth hormone into the bloodstream. It then acts on almost every tissue in the body to control physical functions and processes. With this hormone there is a growth factor1, like insulin that is a hormone produced in the liver and other organs in response to the growth hormone, which then acts back on the hypothalamus to prevent growth hormone-releasing hormone production and stimulate somatostatin secretion. Somatostain helps prevent the release of the growth hormone form the pituitary gland and GHRH production by the hypothalamus, therefore allowing if to act as a powerful suppressor of the growth hormone secretion. According to yourhormones.info, many other factors and physiological conditions such as sleep, stress, exercise and food intake can also have an affect on the hypothalamic release of the growth hormone- releasing hormone and somatostain. Over production of the growth hormone can cause hypothalamic tumors or other tumors located in other parts of the body. There are also other consequences to too much growth hormone- releasing hormone is a rise in growth hormone levels in the bloodstream and in many cases, enlargement of the pituitary gland. In adults, over production of the growth hormone for a long period of time can produce conditions known as acromegaly, which
