and different treatment options available for hyperthyroidism. In healthy people‚ the thyroid makes just the right amounts of two hormones‚ T4 and T3‚ which have important actions throughout the body. These hormones regulate many aspects of our metabolism‚ eventually affecting how many calories we burn‚ how warm we feel‚ and how much we weigh. In short‚ the thyroid "runs" our metabolism. These hormones also have direct

(overactive thyroid) A disease that causes the thyroid to make too much thyroid hormone. Although Graves’ disease can be diagnosed from the results of one or two tests‚ your doctor may use several methods to double-check the findings and rule out other disorders. An analysis of your blood will show if the levels of two hormones- tetraiodothyrinine (free T-4) and triiodothyronine (free T-3)‚ which are produced or regulated by the thyroid- are higher than normal. If they are‚ and if levels of thyroid-stimulating

abnormal thyroid growth however‚ the most common cause of goiters is due to iodine deficiency and cases are more common in developing countries due to the lack of iodine in diets. Iodine is extremely important in thyroid function because it is used in thyroid hormone production. Goiters are more closely associated with Hashimoto’s disease since TSH stimulation causes the thyroid to grow. In some cases‚ goiters can be associated with hyperthyroidism‚ such as Grave’s Disease depending on thyroid hormone

Metabolism and Thyroid Hormone Part 1 1 Which rat had the fastest basal metabolic rate (BMR)? The normal rat had the faster basal metabolic rate‚ because it was not missing its pituitary gland or its thyroid gland. 2 Why did the metabolic rates differ between the normal rat and the surgically altered rats? How well did the results compare with your prediction? The normal rat has the highest BMR because it has the glands required to stimulate and regulate the release of thyroid hormones. 3 If an

Sermorelin is a synthetic hormone which was created to stimulate the production of Growth Hormone (GH) by the pituitary gland in the brain. It is a growth hormone-releasing hormone (GHRH) peptide analogue which contains a peptide sequence of 29 amino acids. It is the shortest synthetic peptide that has all the functional properties of GHRH since it is a copy of the active portion of the natural human GHRH. As such‚ it is a growth hormone secretagogue. GHRH is a hormone produced by the body naturally

immune system attacks the thyroid gland. The thyroid is a small butterfly shaped endocrine gland in the front of the neck which makes hormones T3 (triiodothyronine)‚ and T4 (thyroxine). These hormones regulate metabolism. The thyroid is controlled by hormones secreted by the pituitary gland. The pituitary gland is a pea-sized gland located in the base of the brain which‚ among others‚ makes thyroid stimulating hormone‚ or TSH. TSH stimulates the thyroid to make thyroid hormone. In the case of Hashimoto’s

BODY - IMPORTANT the thyroid is a small gland located below the skin and muscles at the front of the neck. It’s brownish red‚ with left and right halves (called lobes) that look like a butterfly’s wings. It’s light like a butterfly‚ too‚ and usually weighs less than an ounce. As small as it is‚ though‚ the thyroid has an enormously important job to do‚ especially for teens. It manufactures the hormones that help control metabolism and growth. To do its job‚ the thyroid needs a chemical element

result of an overactive thyroid hormone usually resulting from an enlarged thyroid gland‚ and it is most common in older cats. While it does occur in younger cats‚ it is a rare occurrence as only about 5% of cases are from younger cats. [4] The enlargement of the thyroid gland is typically the result of a non-cancerous tumor located in the gland. The thyroid hormone (T3 and T4) is produced in the two thyroid glands in the neck on either side of the trachea. The thyroid hormone regulates metabolism
