Performance enhancing drugs are substances that improve an athlete’s performance. Performance enhancing drugs enlarge muscle size and increase the blood’s oxygen carrying capacity. Although the drug makes a substantial difference in athletic performance, the use of the drug can be medically dangerous. Steroids are outlawed by organizations that govern professional sports. The different substances of PED’s are stimulants, anabolic steroids and erythropoietin. Athletes take these drugs to make…

Triiodothyronine, with a chemical name of 3,3',5-Triiodothyronine (T3), is one of four thyroid hormones that exhibit biological activity, and contains 3 iodines and 2 tyrosine’s, as seen in Fig. 1. 20 % of T3 is formed from the amino acid tyrosine within specific follicle cells of the thyroid gland by the oxidative condensation of its biological precursors, monoiodotyrosine and diiodotyrosine, and is then subsequently secreted into the bloodstream. The remaining 80% is produced from the…

The effect of human growth hormone of pituitary dwarfism in children and adults Introduction Human Growth Hormone is one of the major hormone found in endocrine system in your body. It is an essential hormone that stimulate the body growth, normal brain function and secreted by the somatotropin cells in anterior pituitary gland. There are a condition of abnormal body grow such as pituitary gigantism and pituitary dwarfism which the body over create grow hormone or doesn’t create enough GH.…

thyroid cells and interfere with [their ability to make production of hormones produced in thyroid gland which include triiodothyronine (T3) and thyroxine (T4)]” (Cooper, 2012). When a person has Hashimoto thyroid disease “the immune system produces antibodies that attack the thyroid” (Cooper, 2012). This can cause a persisting impairment of the thyroid causing it to slow the production down of the metabolism-regulating hormones (T3 and T4) which are an essential for bodies to function…

which consists of glands that “produce, store, and release hormones into the bloodstream so they can reach the body’s cells” (Brady, 2015). The thyroid gland generates Triiodothyronine (T3) and Thyroxine (T4) from iodine which develops from foods. The hypothalamus and the pituitary (glands in the brain) “communicate to maintain T3 and T4 balance” (Brady, 2015). The hypothalamus produces a thyroid-stimulating hormone (TSH) releasing hormone (TRH) which signals the Pituitary gland. The Pituitary…

disorders which affects the glands function or structure. This paper will focus on hypothyroidism, its symptoms, treatments and effects on people. Hypothyroidism is a disorder that is common in endocrine and it results from the deficiency of thyroid hormone in the body. The most common cause of hypothyroidism in United States and areas of adequate iodine intake is autoimmune thyroid disease; whereas iodine deficiency in the rest of the world remains the major cause of the disorder. It occurs…

thirst, hunger, body temperature, and sexual behavior that ultimately help maintain a normal internal state. More specifically, the hypothalamus helps the brain secrete essential hormones that thus, govern one’s physiological functions, such as the ones mentioned above, by working with the pituitary gland as well as other hormone secreting glands. While people are driving, the hypothalamus makes drivers aware when they are too hot or too cold so that they may regulate the temperature settings in…

iodine in the food we eat to produce vital hormones like thyroxine or T4 and triiodothyronine, T3, both of which regulate the speed at which your cells metabolic processes function. The thyroid itself is regulated by the pituitary gland and hypothalamus and functions on a feedback system. Much like a thermostat, the body responds to the thyroid’s underproduction of hormones by causing the hypothalamus to produce a hormone called TRH (thyrotropin releasing hormone) which stimulates the pituitary…

” writes William Dudley. He also notes, “However, many people believe that McGwire’s achievement was tarnished by a revelation some weeks earlier that he had been using androstenedione, a compound that temporarily boosts levels of the male sex hormone testosterone” (7). This revelation drew attention to the serious problem of performance- enhancing drug use in professional and amateur sports. In the world of sports, performance enhancing drugs and blood doping can cause health problems,…

Since the beginning of time, man has always been trying to find the competitive edge over one another. But today man’s desire to win is so high, that it seems that they would do whatever it takes. Performance enhancing drugs consist of human growth hormone that increases body muscle mass. Athletes secretly use these enhancements to improve their performance. Athletes should be disciplined severely if they choose to use performance enhancing drugs. The athlete should be banned from the sport…
