Thyroid cells Thyroid-stimulating hormone(TSH)
This hormone has the function of stimulating the thyroid gland and inducing the secretion of thyroid hormones. If the level of thyroid hormones in the blood becomes too high, the amount of TSH secreted by the pituitary gland is reduced and naturally prohibits the secretion of thyroid hormones, just like a thermostat. The location and size of the thyroid gland. The thyroid gland is located in the front part of the neck, just below the Adam's apple. It is about 4 cm in height and weighs about 18 g. It is shaped like a butterfly with its wings wide open. It does this by releasing more thyroid-stimulating hormone (or TSH), which signals your thyroid to make more thyroid hormone. Your thyroid gland then makes and releases the hormone directly into your bloodstream. Your pituitary gland then senses that there is just the right amount of thyroid hormone in your body. The amount of thyroid hormone made by your thyroid gland is adjusted by a gland in the brain called the pituitary. Another part of your brain, the hypothalamus, helps the pituitary. The hypothalamus sends information to the pituitary gland, the pituitary in turn controls the thyroid gland. The thyroid uses iodine, a mineral found in some foods and in iodized salt, to make its hormones. The two most important thyroid hormones are thyroxine (T4) and triiodothyronine (T3). Thyroid stimulating hormone (TSH), which is produced by the pituitary gland, acts to stimulate hormone production by the thyroid gland. The thyroid gland also makes the hormone calcitonin, which is involved in calcium metabolism and stimulating bone cells to add calcium to bone. Various kinds of hormones, including sex hormones, are produced in the body. Organs that produce hormones are called endocrine organs and the thyroid gland is one such organ. It synthesizes thyroid hormones using the iodine contained in food (mainly found in seaweed). The location and size of the thyroid gland. The thyroid gland is located in the front part of the neck, just below the Adam's apple. It is about 4 cm in height and weighs about 18 g. It is shaped like a butterfly with its wings wide open. 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). 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 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 purpose of your thyroid gland is to make, store, and release thyroid hormones into your blood. These hormones, which are also referred to as T3 (liothyronine) and T4 (levothyroxine), affect almost every cell in your body, and help control your body’s functions. The amount of thyroid hormone made by your thyroid gland is adjusted by a gland in the brain called the pituitary. Another part of your brain, the hypothalamus, helps the pituitary. The hypothalamus sends information to the pituitary gland, the pituitary in turn controls the thyroid gland. The function of the pituitary gland. The body has a system to maintain constant levels of thyroid hormones in the blood. The system is controlled by thyroid-stimulating hormone (TSH), which is secreted by a part of the brain called the pituitary gland. The location and size of the thyroid gland. The thyroid gland is located in the front part of the neck, just below the Adam's apple. It is about 4 cm in height and weighs about 18 g. It is shaped like a butterfly with its wings wide open. What does my thyroid gland do? The thyroid gland produces hormones which regulate the body’s metabolic rate as well as heart and digestive function, muscle control, brain development and bone maintenance. The release of thyroid hormones from the thyroid gland is controlled by thyrotrophin-releasing hormone (TRH) from the hypothalamus in the brain and by thyroid stimulating hormone (TSH) produced by the pituitary gland. This forms part of a feedback loop called the hypothalamic-pituitary-thyroid axis.
