Growth hormone

Negative feedback is an important physiological regulation and control. Body water volume is a regulated variable. Disproportion of water volume in the body (too high or too low), require the action of hormone. In case of abnormal loss of body fluids, ADH will help to maintain body fluids by reducing the elimination of urine. ADH impact is example of negative feedback effect, where physiological regulation is maintained. Maintained body Water volume > excessive loos +>…

hormonal growth disorder caused by excess growth hormone that develops when your pituitary gland generates too much growth home during your adulthood. This growth hormone (GH) is released by the pituitary gland, leading to a surplus of growth. The most common symptom of Acromegaly is the enlargement of hands and feet, but it may also include the enlargement of the forehead, jaw, and the nose as well. When GH is released at a moderate and constant level, it grants normal and healthy growth…

glands respectively. Hypothyroidism is an underactive thyroid gland. This means that the thyroid gland doesn’t produce enough thyroid hormone to keep the body running normally. A patient is considered to be hypothyroid is blood works shows too little thyroid hormone in the blood. The abnormally low activity of the thyroid gland could result in retardation of growth and mental development…

is to produce two specific thyroid hormones, triiodothyronine (T3) and thyroxine (T4), and secrete calcitonin that circulates continuously from the gland through the blood to all parts of the body. In fact, thyroid hormones are essential for operating “almost all the cells in the body, regulating basal metabolic rate, lipid metabolism, body temperature, carbohydrate metabolism, and all aspects of linear growth” (Burkhart 55). The pituitary produces the hormone thyrotropin, which is commonly…

an insufficient amount of thyroid hormones. Thyroid hormones are an important part of life. They involve the CNS system, cardiovascular system, reproductive system, appropriate growth/development, and metabolism. According to Agrawal (2015), “Congenital hypothyroidism (CH) is the most common congenital endocrine disorder in childhood and is also one of the most preventable causes of mental retardation.” This disorder is difficult to diagnose because these hormones pass from the mother through…

Bullfrog Dissection Background The American bullfrog, Lithobates catesbeianus, is an amphibian about the size of a teacup.(National Geographic, “American Bullfrog”). This dissection explored the anatomy of a bullfrog that had been pithed. Pithing is a technique used to prevent the frog from experiencing any cruel or unusual pain during the dissection. A pithed frog has had its nervous tissue in its brain severed thus allowing it to maintain normal bodily function during the dissection without…

producing enough hormone, and it may be caused by an autoimmune disorder. HT-H develops when the thyroid gland lacks to produce thyroxine as the body needs. Thyroxine regulates the heart rate, physical growth, digestion. A small amount of hormone can damage organs, tissues in every part of the body. Women are at greater risk than men. HT-H is more common at the age of 50. (Judith Simms, Rebecca. J. Frey,…

iodine-containing, thyroid hormone produced by the thyroid gland. Along with thyroxine, triiodothyronine is also produced in the thyroid gland. Thyroxine usually is converted into triiodothyronine by enzymes in target cells called deiodinases. Concentrations of thyroxine are usually greater in the body, but triiodothyronine is considered the major thyroid hormone. Thyroxine production is controlled by the pituitary gland. The hypothalamus will secrete thyrotropin-releasing hormones that…

Thyroid hormones are essential for physical and mental development. Tyrosine is the inactive form, and most of it is converted to an active formed called triiodothyronine. The production and release of thyroid hormones is controlled by a feedback loop system which involved the hypothalamus and the pituitary and thyroid glands. The hypothalamus secretes thyrotropin-releasing hormone. It then stimulates the pituitary gland to produce a thyroid stimulating hormone. Lastly, this hormones…

Iodine is essential on the new plant and this is why. Iodine is a key component of the hormones made in the thyroid gland. These hormones are absolutely critical to human health, helping to control energy production and utilization in nearly every cell of the body. David Brownstein explains in his books “Iodine: Why You Need It, Why You Can’t Live Without It”, how iodine is crucial in a person’s life by saying “My experience has shown that iodine in doses ranging from 6-50mg/day is adequate…
