Thyroid hormones are hormones produced by the thyroid gland that have roles in metabolism. They are small molecules based on the amino acid tyrosine. The major thyroid hormones are triiodothyronine (T3) and thyroxine (T4), which can be processed by decarboxylation and deiodination by deiodinases, ...
Thyroid gland makes two main hormones. Thyroxine targets most body cells and increases their metabolism to stimulate growth and development. Calcitonin triggers the bone's uptake of calcium from blood. 甲状腺分泌两种主要激素。甲状腺素针对大多数身体细胞,并增加它们的新陈代谢,以刺激生长和发育。降钙素...
Manufacture and release of these hormones into the blood is regulated by thyroid stimulating hormone, TSH, from the pituitary gland. The major effect of TH is to stimulate activity of enzymes involved in energy production through the oxidation (burning) of glucose , thus increasing basal metabolic...
The production of thyroid hormones involves five main steps such synthesis of thyroglobulin (TG), iodide uptake, iodination of thyroglobulin, storage and release. The two important hormones produced by the thyroid gland are Thyroxine (T4) and Triiodothyronine(T3). These two hormones are iodine...
The thyroid gland is a butterfly-shaped endocrine gland located in the neck underneath the cartilage tissue that forms the Adam's apple. By producing hormones such as tri-iodothyronine (T3), tetraiodothyronine (T4) and calcitonin the thyroid gland regulates a number of functions, for...
One of the most important hormones is thyroid stimulating hormone (TSH). TSH is a hormone produced by the pituitary gland that tells the thyroid gland how much thyroid hormone to make. Read on to learn more about low TSH symptoms and treatments. If the pituitary gland is not functioning to...
Histologically, the thyroid gland is composed of follicles. Thyroid follicles consist of a layer of cuboidal epithelial cells surrounding the colloid, an eosinophilic secretion. The homogenous-staining colloid is the reservoir for the thyroid hormones produced by the cuboidal cells. The parafollicular ...
Levels of certain hormones, such as those produced by the thyroid gland, can be factors in depression. In addition, somesymptoms of depressionare associated with thyroid conditions. The same is true about conditions related to the menstrual cycle, such as premenstrual syndrome (PMS), perimenopause...
Hormone - Thyroid Gland, Metabolism, Hormone Production: The two thyroid hormones, thyroxine (3,5,3′,5′-tetraiodothyronine) and 3,5,3′-triiodothyronine, are formed by the addition of iodine to an amino acid (tyrosine) component of a glycoprotein calle
Thyroid gland, endocrine gland that is located in the anterior part of the lower neck, below the larynx (voice box). The thyroid secretes hormones vital to metabolism and growth. Any enlargement of the thyroid, regardless of cause, is called a goitre. Th
