The growth hormone is an essential hormone composed of around 190 amino acids, which controls several important physiological processes such as growth and metabolism. It is secreted by cells called somatotrophs previously called slimey.
The growth hormone directly directly affects its effects as well. The immediate effects occur when the hormone on specific receptors is currently on cells. For example, the fat cells which are meant as adipocyte receptors promoted by the growth hormone to cleave triglyceride. The hormone also prevents these receptors from incorporating permeating lipids.
The Impact of Growth
The indirect effects are mediated by the effect of growth hormone on a different hormone terminated by the liver, the insulin-as growth factor-1 (igf-1). The secretion of igf-1 has a range of growth-promoting effects when acting on cellular targets. Igf-1 promotes the growth of various tissues and also promotes osteoblast and chondrocyte activity to increase bone growth. Igf-1 also plays an important role in muscle growth, promoting the differentiation and proliferation of an ancestral type called a myoblast that leads muscle to cells. When myoblasts melts, they form skeletal muscle fibers in which the multiple nuclei can be detected from an individual myoblast by virtue of each nucleus.
The growth hormone plays an important role in the metabolism of lipids, proteins and carbohydrates. In some cases, these effects of growth hormone are immediate, while others in Igf-1 are the main mediator. In other cases, the effects of the growth hormone are both direct and indirect.
Growth hormone promotes the use of lipids by promoting triglyceride and oxidation in cells.
In various different tissues, it enhances growth hormone understanding of amino acids and protein synthesis, as well as decreasing protein oxidation.
The metabolism of the carbohydrate
The growth hormone is involved in the blood glucose regulation. It exercises anti-insulin activity by suppressing insulin capacity to promote glucose penetration into the peripheral tissues. It also increases gluconeogenesis in the liver.
The hormone and growth disease
Both a deficiency and an excess of the growth hormone are associated with disease states.This disorder may occur due to abnormalities in the mucous gland, the hypothalamus or the target cells of the hormone.
The growth hormone deficiency can occur as a result of inadequate production of the hormone or due to an inadequate receptor response to the hormone. This can lead to delayed growth or dwarf growth, although this depends on the age at which the deficiency began. The effect of excessive growth hormone also depends on the age at which the deficiency developed. The two major conditions associated with excess in the growth hormone production are gigantism and acromegaly.
Gigantism and acromegaly
As growth hormone promotes the growth of bones, muscles and various other organs, it causes too much of the abnormal growth of all of these tissues, a condition that is meant to be gigantism when it applies to children and acromegaly when applied to adults is. Almost all cases are caused by a benign tumor in the mucous gland called adenoma, although some rare tumors present in the lungs or pancreas can also secrete hormones that cause the mucous gland to produce too much growth hormone. The effect in children is increased height, while the adults develop bone marrow formation. Other common problems include visual disturbances, weakness and heart failure.
The conditions are diagnosed based on X-rays and blood tests, while data processed tomography and magnetic resonance imaging are performed to try and determine the cause.The Treatment includes a combination of radiotherapy, surgery and medicine to reduce the growth hormone production.
Synthetic Human Growth Hormone (HGH) was approved for use by FDA in 1985 as a short-term and poor growth treatment due to conditions such as Turner’s syndrome, prader-Willi syndrome and the growth hormone deficiency. However, the drug is most commonly used for reasons that are not approved by FDA. Available widely over the Internet, people often assign a job to HGH in combination with other drugs to build muscle and improve their athletic performance, despite the consequences for performance that does not fully understand. Some researchers also believe that HGH can reverse the physical deterioration that prevents people from aging, although this effect is also not proven.
Possible side effects associated with HGH use include carpal tunnel syndrome, nerve or muscle pain, joint pain, elevated cholesterol level, fluid accumulation (edema) and numbness or tingling in the skin.
