The thyroid is one of the larger endocrine glands in the body. It is located in the neck and produces hormones, principally thyroxine and triiodothyronine, that regulate the rate of metabolism and affect the growth and rate of function of many other systems in the body. Thyroid - Anatomy. Thyroid - Gross anatomy. The thyroid is situated on the front side of the neck at the level of C5 to T1 vertebral bodies, just below the laryngeal prominence (Adam's apple), near the thyroid ca ...

Thyroid - Medical treatment. Levothyroxine is a stereoisomer of thyroxine which is degraded much slower and can be administered once daily in patients with hypothyroidism. Graves' disease may be treated with the thioamide drugs propylthiouracil, carbimazole or methimazole, or rarely with Lugol's solution. Hyperthyroidism as well as thyroid tumors may be treated with radioactive iodine. ...

Sarvangasana, the Sanskrit name for the Shoulderstand, comes from the word "sarva", meaning whole. This Asana strengthens your entire body; it gives many of the benefits of the Headstand, but here the circulation is directed to your thyroid gland instead of the head.

The primary function of the thyroid is production of the hormones thyroxine (T4), triiodothyronine (T3), and calcitonin. Up to 40% of the T4 is converted to T3 by peripheral organs such as the liver and spleen. Thyroid - T3 and T4 production and action. Thyroxine is synthetised by the follicular cells from the tyrosine residues of the protein called thyroglobulin (TG). Iodine, captured with the "iodine trap" is activated by the enzyme thyroid peroxidase (TPO) and linked to the 3' and 5' sites of the benzen ...

Calcitonin is a a 32 amino acid polypeptide hormone that is produced in humans primarily by the C cells of the thyroid, and in many other animals in the ultimobranchial body. Calcitonin - Synthesis. It is formed by proteolytic cleavage of a larger prepropeptide which is the product of the CALC1 gene, which itself is part of a superfamily of related protein hormone precusors including Islet Amyloid Precursor Protein, Calcitonin Gene-Related Peptide and the precursor of Adrenomedullin.

The parathyroid glands are small endocrine glands in the neck, usually located within the thyroid gland, which produce parathyroid hormone. Most often there are four parathyroid glands but have been known to number six or eight. Parathyroid gland - Anatomy. The parathyroid glands are four small glands located on the posterior (closer to the back) surface of the thyroid gland. They distinguish themselves from the thyroid gland histologically as they contain two types of cells- parathyroid chief cells and oxy ...

The cricothyroid muscle attaches to the anterolateral aspect of the cricoid and the inferior cornu and lower lamina of the thyroid cartilage, tilting the thyroid forwards and lengthening the vocal cords. It's the only laryngeal muscle supplied by the external laryngeal nerve (rather than the recurrent laryngeal nerve).

The human larynx rests in a frame of cartilage bound by ligaments and muscles. At the front is the thyroid cartilage, creating the lump at the front of the neck, known as the laryngeal prominence or more commonly as the Adam's apple. The etymology of the term "Adam's apple" is unclear: Webster's 1913 dictionary states that the term "... is so called from a notion that it was caused by the forbidden fruit, (an ...

The cricoid cartilage, or simply cricoid, is the only complete ring of cartilage around the trachea. It sits just inferior to the thyroid cartilage in the neck, and is joined to it medially by the median cricothyroid ligament and postero-laterally by the cricothyroid joints. Inferior to it are the rings of cartilage around the trachea (which are not continuous - rather they are C-shaped with a gap posteriorly). The cricoid is joined to the first tracheal ring by the cricotracheal ligament, and this can be felt as a more yielding area between ...

A gland is an organ in an animal's body that synthesizes a substance for release such as hormones, often into the bloodstream (endocrine gland) or into cavities inside the body or its outer surface (exocrine gland). Gland - Types of gland. Humans have a large variety of glands, from the pituitary gland in the brain, to sweat glands over the body's skin that release perspiration to regulate the body's temperature.

Cretinism (most likely from the Latin Christiānum, "Christian") is a condition of severely stunted physical and mental growth due to untreated congenital deficiency of thyroid hormones (hypothyroidism). The term cretin refers to a person so affected. Cretinism - Etymolology and usage of the term. The term cretin was brought into medical use in the 18th century from an Alpine French dialect where persons with such a condition were especially common (though the cause was unknown). It was ...

Most of the thyroid hormone circulating in the blood is bound to transport proteins : Thyroxine-binding globulin (TBG) Thyroid binding prealbumin (TBPA) - this protein is also responsible for the transport of retinol, and so now has the preferred name of transthyretin (TTR) albumin Only a very small fraction of the circulating hormone is free (unbound) - T4 0.03% and T3 0.3%. This free fraction is biologically active, hence measuring concentrations of free thyroid hormon ...

Thyroxine (3,5,3',5'-tetra­iodothyronine) is produced by follicular cells of the thyroid gland. It is produced as the precursor thyroglobulin (this is not the same as TBG), which is cleaved by enzymes to produce active T4. Thyroxine is produced by attaching iodine atoms to the ring structures of tyrosine molecules. Thyroxine contains four iodine atoms. Triiodothyronine is identical to T4, but it has one less iodine atom per molecule. Iodide is actively absorbed from the bloodstream and conce ...

Thyroid: The thyroid gland produces hormones that are essential for normal body metabolism. This gland is located in the lower part of the neck, below the Adam's apple. The gland wraps around the windpipe (trachea).

The hypothalamus produces thyrotropin-releasing hormone (TRH) which stimulates the pituitary gland to release TSH. TSH stimulates the thyroid gland to secrete the hormones thyroxine (T4) and triiodothyronine (T3). The production of TSH is inhibited by the production of somatostatin by the hypothalamus. T3 and T4 also inhibit TSH production and secretion, creating a regulatory negative feedback loop. TSH consists of two subunits, the alpha and the beta subunit. The α (alpha) subunit is identical to that of human c ...

Hypothyroidism - Neonatal hypothyroidism. Thyroid hormone is very important to neural development in the neonatal period. A deficiency of thyroid hormones can lead to cretinism. For this reason it is important to detect and treat thyroid deficiency early. In Australia, the Netherlands, and many other countries this is done by testing for TSH on the routine neonatal heel pricks performed by law on all newborn babies. Hypothy ...
