Thyroid stimulating hormone or TSH.It is secreted by anterior pitutory
chickens
The disease that is associated with excessive amounts of thyroid hormones is hyperthyroidism. Hyperthyroidism is a thyroid condition that causes the thyroid to become overactive. An overactive thyroid produces too much thyroid stimulating hormones.
thyroid hormones
An element that causes thyroid trouble is IodineIodine
You have the various releasing factors, that come from the hypothalamus. The low level of the hormones from the target organ like thyroid may stimulate thyroid stimulating hormone from the pituitary.
it stimulates the thyroid to produce the thyroid hormone which regulates metabolic rate
The thyroid gland needs iodine for optimal function, lack of iodine causes the thyroid to swell (called goiter) and over produce hormones.
Grave's disease is an autoimmune disease which causes hyperthyroidism.(particularly in the developed countries). normally TSH combines with the surface receptors of thyroid cells and causes the synthesis and secretion of thyroid hormones. in Grave's disease the thyroid stimulating autoantibodies (B-TSAB) produced by B lymphocytes activate the TSH receptors and increase the secretion of thyroid hormones(thyroxine and triiodothyronine). Grave's disease is due to elevated thyroid stimulating IgG also knoen as long acting thyroid stimulator (LATS) which activates TSH and, thereby, increases thyroid hormonal production.
The long-acting thyroid stimulator (LATS) test shows whether blood contains long-acting thyroid stimulator. Not normally present in blood, LATS causes the thyroid to produce and secrete abnormally high amounts of hormones.
An underactive thyroid occurs with the thyroid doesn't produce enough thyroid hormones. This is most commonly referred to as hypothyroidism. An underactive thyroid also occurs due to Hashimoto's thyroiditis (a thyroid autoimmune condition) as well as postpartum thyrioditis. Thyroid conditions are hereditary in nature, especially among women.
The thyroid hormones thyroxine and tri-iodothyronine are under produced. It is these hormones that regulate the rate of the metabolic process so a lack of them slows down bodily functions.
Try looking up "Wilson's Temperature Syndrome." An imbalance of the hormones the Thyroid produces. The typical thyroid test may show that it is working normally, which it probably is. Good luck.
