The thyroid hormones, thyroxine ( T4) and triiodothyronine ( T3), are tyrosine-based hormones produced by the thyroid gland. An important component in the synthesis of thyroid hormones is iodine. The major form of thyroid hormone in the blood is thyroxine (T 4), which has a longer half life than T 3. The ratio of T 4 to T 3 released in the blood is roughly 20 to 1. Thyroxine is converted to the active T 3 (three to four times more potent than T 4) within cells by deiodinases (5'-iodinase). These are further processed by decarboxylation and deiodination to produce iodothyronamine ( T1a) and thyronamine ( T0a). Most of the thyroid hormone circulating in the blood is bound to transport proteins. Only a very small fraction of the circulating hormone is free (unbound) and biologically active, hence measuring concentrations of free thyroid hormones is of great diagnostic value. When thyroid hormone is bound, it is not active, so the amount of free T3/T4 is what is important. For this reason, measuring total thyroxine in the blood can be misleading. T3 and T4 cross the cell membrane easily as they are lipophilic molecules, and function via a well-studied set of nuclear receptors in the nucleus of the cell, the thyroid hormone receptors.

8. HGH - The Thyroid Gland and Thyroid Hormone
September 21, 2009
The thyroid gland is a butterfly shaped gland that is located over the trachea (wind pipe) just below the larynx (voice box). The thyroid gland plays a very important role in most all the metabolic processes of the body. The thyroid gland with its thyroid hormone is responsible for regulating metabolism.
How Thyroid Hormone is Made
The hypothalamus, often referred to as the body's "thermostat" is responsible for making sure the thyroid blood levels are normal. When the hypothalamus notices the thyroid blood levels decreasing it releases TRH (thyroid releasing hormone). The TRH then s... (read more)

9. How Levothroid can help you overcome thyroid deficiency
September 18, 2009
The thyroid gland is a small, butterfly - shaped endocrine gland found in the front base of the neck. It is one of the largest endocrine glands in the body and produces two thyroid hormones - Thyroxine (T4) and Triiodothyronine (T3), which mainly regulate the body’s metabolic rate as well as regulate the growth and functioning of other body systems. This gland also produces calcitonin, a hormone that plays an important role in a process called calcium homeostasis (a process by which the body maintains calcium levels). The thyroid gland may be affected by two common disorders, viz.,... (read more)

"Your thyroid levels are in the normal range now, take these antidepressant's, they will help with your depression." These may be some of the most dangerous words a low thyroid sufferer will ever hear.According to the Endocrine Society, eighty to ninety percent of hypothyroidism in the United States, stems from an autoimmune mechanism called Hashimoto's Autoimmune Thyroid. This means the source of the low thyroid function is the immune system attacking your own gland. Your thyroid hormone levels will slowly decrease over time because it continually loses cells from the immune attack.Here are 5... (read more)

15. Parathyroid Glands Gone Bad - Causes of Benign Tumors and Other Disorders of the Parathyroid Glands
August 03, 2009
On average, a person has four parathyroid glands — two of which are located in the posterior left lobe of the thyroid gland and another two on the posterior of the right lobe. Combined, these four weigh less than 500 mg. Each gland is composed mainly of chief cells, which synthesize and secrete parathyroid hormone or parathormone or PTH for short.
PTH is responsible for resorption of bone in cases of low calcium levels. These hormones tap into the calcium-rich source which is the bone and act on the osteocytes and osteoclast to begin pumping calcium out of the bone and into the extracellu... (read more)

16. Nonsurgical Parathyroid Treatments - Parathyroid Treatments Without Going Under the Knife
August 03, 2009
Parathyroid treatments are used to treat the disorders that have something to do with the way your body regulates your calcium levels. One of the most common disorders of the parathyroid glands is hyperparathyroidism, which is an increase in the synthesis and secretion of parathyroid hormone or PTH. An increase of PTH will cause resorption of bone, leading to bone weakness.
Hypoparathyroidism may not be as common as hyperparathyroidism but it bears watching as well. Hypoparathyroidism is the opposite of hyperparathyroidism. In hypoparathyroidism, there is inadequate secretion of PTH by th... (read more)

17. Hypothyroidism and Goiter - Hypothyroidism Causes Enlargement of the Thyroid
August 03, 2009
Hypothyroidism, in general, has exactly the opposite effects as those of hyperthyroidism, although it may be caused by autoimmunity as well but a kind of immunity that destroys the gland rather than stimulates it. Most of the patients first have autoimmune thyroiditis, an inflammation of the thyroid glands. This causes deterioration and eventually, fibrosis of the gland or the replacement of thyroid tissue with connective tissue. Fibrotic tissue is incapable of producing thyroid hormone and a deficiency in the hormone occurs. In most cases, an enlagement of the thyroid gland is observed.

21. Hyperthyroidism in the Form of Graves' Disease - Understanding Graves' Disease
August 03, 2009
What is Graves' Disease? One of the most common disorders involving the thyroid is Graves' disease. Since it was first described by the Irish physician Robert James Graves, it has become the leading cause of hyperthyroidism in the world.
Graves' disease is an autoimmune disease caused by antibodies that mimic the effects of the hormone thyroid-stimulating hormone produced by the pituitary gland. These antibodies cause the thyroid gland to produce more and more thyroid hormone beyond the normal limits. This causes the body's metabolism to speed up, resulting in the symptoms of hyperthyroid...

22. Fate of Iodine in Thyroid Hormone Formation - Why Iodine is Necessary For Thyroid Hormone Formation
August 03, 2009
To form sufficient quantities of the thyroid hormone thyroxine or T4, about 50 milligrams of iodine in the form of iodides in the diet is required every year. This just shows how important iodine is in the process of thyroid hormone formation and consequently, the regulation of the body’s metabolism. Iodides in the Diet
The iodides available in your food are absorbed in the gastrointestinal in much the same way as chlorides. These are then normally rid of by the kidneys through the urine but not before the thyroid gland gets its share of iodides. This share constitutes about a fifth of t... (read more)

23. The Parathyroid Counterpart - The Complete Opposite of the Parathyroid Hormone
August 03, 2009
The parathyroid hormone is not without a counterpart to regulate its effects on the body. Although parathyroid hormone is mainly secreted in response to low calcium and phosphate levels, the body maintains another mechanism to decrease the levels of calcium should it rise beyond normal levels.
What is the Parathyroid Counterpart? Calcitonin is a peptide hormone composed of 32 amino acids with a molecular weight of about 3400. It is synthesized and secreted by the parafollicular cells or C cells of the thyroid gland. These cells constitute just about 0.1% of the whole thyroid gland.

25. The Face of Hyperthyroidism - The Causes, Symptoms, Diagnosis, and Treatment of Hypothyroidism
August 03, 2009
Hyperthyroidism is defined as the excessive production of thyroid hormone. This condition leads to several physiologic effects that may alter even the physical appearance of a patient with hyperthyroidism. Thyroid hormone controls most of the body’s metabolism and this ability is made manifest in force in cases of hyperthyroidism.
What Causes Hyperthyroidism?
Patients with hyperthyroidism normally have thyroid glands that are two to three times larger than a normal thyroid gland. These hyperthyroid glands are characterized by increased cell proliferation and infolding of the follicul... (read more)
