Complaints under a thyroid hormone disorder According to the functions described above: An underfunctioning of the thyroid gland (hypothyroidism), as occurs for example in the case of iodine deficiency, leads accordingly to opposite symptoms: The causes of these diseases are very different and can be congenital, autoimmune (Graves’ disease) or caused by a tumor. The … Complaints under a thyroid hormone disorder | Thyroid hormones
Summary The thyroid gland produces two important thyroid hormones, the biologically largely ineffective thyroxine (T4) and the effective triiodothyronine (T3). They are synthesized in the thyroid cells with the help of iodine and are released from the thyroid follicles as required. The effective T3 is released directly from the thyroid gland in much lower concentrations, … Summary | Thyroid hormones
Formation of T3T4: These thyroid hormones are formed in the thyroid gland, or more precisely in its follicles (roundish structures of cells), from the amino acid thyrosine. There are two types of hormones known as thyroid hormones. T4 hormones occur in the blood about 40 times more than T3 hormones, but T3 acts faster and … T3 – T4 – Hormones
Definition Hormones are messenger substances that are produced in glands or specialized cells of the body. Hormones are used to transmit information to control metabolism and organ functions, whereby each type of hormone is assigned a suitable receptor on a target organ. To reach this target organ, hormones are usually released into the blood (endocrine). … Hormones
Tasks of hormones Hormones are messenger substances of the body. They are produced by various organs (for example thyroid, adrenal gland, testicles or ovaries) and released into the blood. In this way they are distributed to all areas of the body. The different cells of our organism have different receptors to which special hormones can … Tasks of hormones | Hormones
Thyroid hormones The thyroid gland has the task of producing hormones from various amino acids (protein building blocks) and the trace element iodine. These have a variety of effects on the body and are particularly necessary for a normal course of growth, development and metabolism. Thyroid hormones have an influence on almost all cells of … Thyroid hormones | Hormones
Hormones of the adrenal gland The adrenal glands are two small, hormone-producing organs (so-called endocrine organs), which owe their name to their location next to the right or left kidney. There, various messenger substances with different functions for the body are produced and released into the blood. An important type of hormone is the so-called … Hormones of the adrenal gland | Hormones
Hormone-related diseases In principle, disorders of hormone metabolism can affect any hormone gland. These disorders are called endocrinopathies and are usually manifested as over- or underfunction of the endocrine gland for a variety of reasons. As a result of the functional disorder, hormone production increases or decreases, which in turn is responsible for the development … Hormone-related diseases | Hormones
Introduction Among the hormones of the pancreas are the following: Insulin Glucagon Somatostatin (SIH) Education Education: The hormones of the pancreas are produced in the so-called Langerhans cells, whereby three different types are known: In the alpha cells the hormone glucagon is produced, in the beta cells insulin and in the delta cells somatostatin (SIH), … Hormones of the pancreas
Formation of prolactin: The hormone prolactin of the pituitary gland is also called lactotropin and is a peptide hormone. Regulation Regulation of prolactin: The PRH (prolactin releasing hormone) and the TRH (thyrooliberin) of the hypothalamus stimulate the release of prolactin from the anterior pituitary gland, which has a day-night rhythm. Oxytocin and several other substances … Prolactin
Androgens refer to the male sex hormones. Among them are: In men, these hormones are produced in the testicles (Leydig cells) and in the adrenal cortex. In women, they are produced in the ovary and also in the adrenal cortex. In the blood, the transport of androgens takes place either bound to the protein albumin … Androgens
Production of adrenaline: These stress hormones adrenaline and noradrenaline are produced in the adrenal medulla and in nerve cells starting from the amino acid tyrosine. With the help of enzymes, this is first converted into L-DOPA (L-dihydroxy-phenylalanine). Then dopamine, noradrenaline and adrenaline are produced enzymatically with the help of vitamins (C, B6), copper, folic acid … Adrenalin
