Function thyroid

Thyroid Function Tests: The thyroid function Test is to ensure the Thyroid Stimulating Hormone level in a blood sample. A high Thyroid Stimulating Hormone level indicates that the thyroid gland is failing because of a problem that is directly affecting the thyroid. The opposite situation, in which the Thyroid Stimulating Hormone level is low, usually indicates that the person has an overactive thyroid that is producing too much thyroid hormone. The free thyroxine fraction test is the most important to determine how the thyroid is functioning, and tests to measure this are called the Free thyroxine and the Free thyroxine Index (FT4I or FTI). The finding of an elevated TSH and low FT4 or FTI indicates primary hypothyroidism due to disease in the thyroid gland. A low Thyroid Stimulating Hormone and low FT4 or FTI indicates hypothyroidism due to a problem involving the pituitary gland. A low Thyroid Stimulating Hormone with an elevated FT4 or FTI is found in individuals who have hyperthyroidism.

Thyroid Gland Function: The thyroid gland function under the control of the pituitary gland, a small gland the size of a peanut at the base of the brain. The thyroid’s job is to make thyroid hormone, which is secreted into the blood and then carried to every tissue in the body. Thyroid hormone is essential to help each cell in each tissue and organ to work right. The thyroid gland is supplied by two pairs of arteries: the superior and inferior thyroid arteries of each side. The superior thyroid artery is the first branch of the external carotid, and supplies mostly the upper half of the thyroid gland, while the inferior thyroid artery is the major branch of the thyrocervical trunk, which comes off of the subclavian artery. he thyroid gland is prone to several very distinct problems, some of which are extremely common. These problems can be broken down into those concerning the production of hormone (too much, or too little), those due to increased growth of the thyroid causing compression of important neck structures or simply appearing as a mass in the neck, the formation of nodules or lumps within the thyroid which are worrisome for the presence of thyroid cancer, and those which are cancerous.

Function Thyroid: Low stimulation When function thyroid low stimulate hormones, the pituitary gland produces Thyroid Stimulating Hormone which stimulates the thyroid gland to produce more hormones. Under the influence of TSH, the thyroid will manufacture and secrete T3 and thyroxine thereby raising their blood levels. The pituitary gland senses this and responds by decreasing its TSH production. Thyroid gland hormones behaves are like heat mechanism. When the heat gets back to the thermostat, it turns the thermostat off. As the room cools (the thyroid hormone levels drop), the thermostat turns back on (TSH increases) and the furnace produces more heat (thyroid hormones).

Thyroid Hormone Function: The thyroid gland hormone function is to Produce thyroxine and triiodothyronine, are tyrosine-based hormones. The most important component in the synthesis is iodine. The thyroid hormones are essential to proper development and differentiation of all cells of the human body. These hormones also regulate protein, fat, and carbohydrate metabolism, affecting how human cells use energetic compounds. Numerous physiological and pathological stimuli influence thyroid hormone synthesis.
