Regulation of healthy hormones in the body. Thyroid hormone is responsible for the regulating the metabolic rate of every cell in the body
Background. Thyroid hormone is responsible for the regulating the metabolic rate of every cell in the body Since every cell in the body depends on its metabolism to perform its function, when the thyroid system is malfunctioning it can affect every system of the body.  Hyperthyroidism occurs when the gland produces excessive amounts of thyroid hormones, the most common cause being Graves' disease —an autoimmune disorder. In contrast, hypothyroidism is a state of insufficient thyroid hormone production. Worldwide, the most common cause is iodine deficiency. The thyroid gland is a butterfly-shaped organ and is composed of two cone-like lobes or wings, lobus dexter (right lobe) and lobus sinister (left lobe), connected via the isthmus. Each lobe is about 5 cm long, 3 cm wide and 2 cm thick. Having thyroid hormone levels that are too high (overactive thyroid gland). Sometimes the thyroid gland makes too much thyroid hormone, which is called hyperthyroidism. Think of your body as a car and your thyroid as the engine. An overactive thyroid makes your body idle too fast. The primary function of your thyroid gland is to secrete thyroid hormones, which are responsible for controlling your body’s metabolism. The 2 main thyroid hormones are T3 (triiodothyronine) and T4 (thyroxine). The amount of thyroid hormones secreted is controlled by another hormone, called thyroid stimulating hormone (TSH), which is released from the pituitary gland in your head. The function of the thyroid gland is to take iodine, found in many foods, and convert it into thyroid hormones: thyroxine (T4) and triiodothyronine (T3). Thyroid cells are the only cells in the body which can absorb iodine. These cells combine iodine and the amino acid tyrosine to make T3 and T4.  The thyroid gland is part of the endocrine system and is responsible for producing and releasing thyroid hormones into the bloodstream. Collectively, T3 and T 4 are referred to as the thyroid hormones. Twenty percent of the body’s triiodothyronine is made by the thyroid gland; the other 80% comes from thyroxine converted by organs such as the liver or kidneys. The thyroid gland also produces calcitonin from cells called C-cells. The thyroid gland, or simply the thyroid /ˈθaɪrɔɪd/ , is one of the largest endocrine glands in the body, and consists of two connected lobes. It is found in the neck, below the laryngeal prominence (Adam's apple). The thyroid gland is a butterfly-shaped organ and is composed of two cone-like lobes or wings, lobus dexter (right lobe) and lobus sinister (left lobe), connected via the isthmus. Each lobe is about 5 cm long, 3 cm wide and 2 cm thick. The hormones secreted by the thyroid gland are the triiodothyronine (T3), thyroxine (T4) and the thyrocalcitonin which is responsible for the calcium reabsorption or breakdown. T3 and T4 are the two primary hormones responsible for metabolism. The anterior pituitary gland signals the thyroid gland to secrete hormones. The Anatomy. The thyroid gland is one part of the endocrine system which is primarily responsible for the regulation of healthy hormones in the body. The thyroid gland is considered as one of the largest endocrine glands in the body. It weighs 2-3 grams in newborns and 18-60 grams in adult It participates in these processes by producing thyroid hormones, the principal ones being thyroxine (T 4) and triiodothyronine (T 3), which is more active. These hormones regulate the growth and rate of function of many other systems in the body. T 3 and T 4 are synthesized from iodine and tyrosine. The thyroid gland is a butterfly-shaped organ and is composed of two cone-like lobes or wings, lobus dexter (right lobe) and lobus sinister (left lobe), connected via the isthmus. Each lobe is about 5 cm long, 3 cm wide and 2 cm thick.
