	The thyroid hormones T3 and T4 have a number of metabolic, cardiovascular and developmental effects on the body. The production is stimulated by release of thyroid stimulating hormone (TSH), which in turn depends on release of thyrotropin releasing hormone (TRH). Every downstream hormone has negative feedback and decreases the level of the hormone that stimulates its release. The thyroid gland also produces the hormone calcitonin, which helps regulate blood calcium levels.

The thyroid gland also produces the hormone calcitonin, which helps regulate blood calcium levels. About 20,000 protein-coding genes are expressed in human cells: 70% of these genes are expressed in thyroid cells.

	The primary function of the thyroid is the production of the iodine-containing thyroid hormones, triiodothyronine (T3) and thyroxine or tetraiodothyronine (T4) and the peptide hormone calcitonin.~~[24]~~ The thyroid hormones are created from iodine and tyrosine. T3 is so named because it contains three atoms of iodine per molecule and T4 contains four atoms of iodine per molecule. The thyroid hormones have a wide range of effects on the human body.

The thyroid hormones have a wide range of effects on the human body. These include:

	*Metabolic. The thyroid hormones increase the basal metabolic rate and have effects on almost all body tissues. Appetite, the absorption of substances, and gut motility are all influenced by thyroid hormones.They increase the absorption in the gut, generation, uptake by cells, and breakdown of glucose. They stimulate the breakdown of fats, and increase the number of free fatty acids. Despite increasing free fatty acids, thyroid hormones decrease cholesterol levels, perhaps by increasing the rate of secretion of cholesterol in bile.		*Metabolic.

	*Cardiovascular. The hormones increase the rate and strength of the heartbeat. They increase the rate of breathing, intake and consumption of oxygen, and increase the activity of mitochondria. Combined, these factors increase blood flow and the body's temperature.		*Cardiovascular. The hormones increase the rate and strength of the heartbeat.

	The thyroid, or [[Thyroid Gland]], is an endocrine gland in vertebrates. In humans, it is in the neck and consists of two connected lobes. The lower two thirds of the lobes are connected by a thin band of tissue called the isthmus. The thyroid gland is a butterfly-shaped gland located in the neck below the Adam's apple. The thyroid is near the front of the neck, lying against and around the front of the larynx and trachea.		The thyroid, or [[Thyroid Gland]], is an endocrine gland in vertebrates.

The thyroid gland is a butterfly-shaped gland located in the neck below the Adam's apple. The thyroid is near the front of the neck, lying against and around the front of the larynx and trachea.

	Microscopically, the functional unit of the thyroid gland is the spherical thyroid follicle, lined with follicular cells (thyrocytes), and occasional parafollicular cells that surround a lumen containing colloid. The thyroid gland secretes three hormones: the two thyroid hormones – triiodothyronine (T3) and thyroxine (T4) – and a peptide hormone, calcitonin. The thyroid hormones influence the metabolic rate and protein synthesis and growth and development in children.

	~~==Development==~~
	In the development of the embryo, at 3–4 weeks gestational age, the thyroid gland appears as an epithelial proliferation in the floor of the pharynx at the base of the tongue between the tuberculum impar and the copula linguae. The copula soon becomes covered over by the hypopharyngeal eminence at a point later indicated by the foramen cecum. The thyroid then descends in front of the pharyngeal gut as a bilobed diverticulum through the thyroglossal duct. Over the next few weeks, it migrates to the base of the neck, passing in front of the hyoid bone. During migration, the thyroid remains connected to the tongue by a narrow canal, the thyroglossal duct. At the end of the fifth week the thyroglossal duct degenerates, and over the following two weeks the detached thyroid migrates to its final position.<ref>[https://en.wikipedia.org/wiki/Thyroid wiki]</ref>
