Thyroxine

The thyroid is a gland located in the front of the neck. It is also below the larynx. It produces two different hormones. These hormones are called triiodothyronine, or T#3, and thyroxine, T4.Thyroid hormones are inside of the body’s bloodstream. They’re on every tissue and cell in the entire body. Hyperthyroidism is a condition that results from excessive production of thyroid hormones. One of the most common causes of this is an autoimmune disease called Graves’ disease. If a patient has…

lead to such improved treatments. He and his team at Rush have led an international effort that provides a better understanding of what happens when hypothyroid patients are treated with levothyroxine, a synthetic version of the thyroid hormone thyroxine, which also is known as L-T4. Using hypothyroid rats, the team observed that normalization of thyroid action in the parts of the body where it is especially important -- the brain, the liver and the skeletal muscles -- occurred only when…

The first is biological factors which include genetic susceptibility, increased number of adipose cells formed during childhood, hormonal imbalance such thyroxine produced be the thyroid gland (Marieb & Hoehn, 2010). Psychological factors are also responsible for obesity such as depression and stress. Each individual copes differently to stress and depression, some individuals tend to eat more when under stress…

the cellular utilization of glucose as an energy source, when used by endurance athletes it increases fat metabolism instead of CHO. HGH stimulates the catabolism of fats and the conversion of glycogen to glucose. Combined with the stimulation of Thyroxine (TSH) and HGH increase catabolism thereby the result is an additional supply of energy to the body. There are some other impacts of HGH which are negative. One of which is the hypersecretion of HGH. This produces gigantism, in adults’ bones of…

Thyroid Storm The hypothalamus, the anterior pituitary gland, and the thyroid gland all work together to regulate the thyroid hormones which in turn have a significant role in the regulation of the body’s metabolism and calcium balance (Pullen & Embrey, 2013, p. 14). When these components fail to maintain the appropriate balance of the thyroid hormones, the result can be either a hyperactive thyroid or a hypoactive thyroid. As a nurse, it is important to be able to identify patients who may be…

The Endocrine System is considered to be an integrative system because the hormones which are produced by this system act at the distance, many of those substances act in the different organs. The endocrine system and nervous system work together to coordinate functions of all systems in human body, they are responsible for maintaining the internal environment, nearly all physiological processes are affected by the hormones. They regulate almost all body function starting from metabolism, grow…

Disease Overview Type 1 or classic galactosemia is autosomal recessive disease that has the potential to become lethal. This disease causes the inability for newborns to process galactose within their liver. This can be fatal as rising levels of galactose within the body can be very toxic. Even individuals who survive the high level of galactose would obtain neurological damage. This disease has several variations, however, this particular manifestation is the result of gene that encode for…

Hashimoto’s Disease, also known as Chronic Lympocytic Thyroiditis, is an autoimmune disease that attacks a person’s thyroid gland. It is a type of hypothyroidism that gradually leads to atrophy of the thyroid tissue. There are several signs and symptoms a person will experience when Hashimoto’s disease is present. Consulting a doctor is crucial for diagnosis and treatment of this disease for a positive prognosis. Though there is still a lot unknown about this disease, remission is possible and…

The cardiovascular system, or blood-vascular system is comprised of the heart and blood vessels. The heart is the strongest pumping muscle in the body. Important mechanics of the heart allows the heart to properly do its job The heart is responsible for intrinsic cardiac conduction, the cardiac cycle, and cardiac output. The blood vessels in the cardiovascular system are just as important. The blood vessels aid in blood flowing to body tissue, maintaining blood pressure, and controlling blood…

change and the brain will send a message back ordering vasodilation, therefore allowing heat to escape. If this isn’t enough the brain triggers sweating, increased breathing rate, “for erector muscles to lie flat, no shivering and for less adrenaline/thyroxine to be released.” (Parsons, 2009,…
