Introduction The thyroid gland produces two different hormones, thyroxine (T4) and triiodothyronine (T3). The synthesis and release of these hormones is regulated by the hypothalamus and pituitary gland. Their main purpose is to increase the energy metabolism. The thyroid gland produces the hormones T3 and T4 on the one hand and calcitonin on the other. … Thyroid hormones
Transport in blood Both thyroxine (T4) and triiodothyronine (T3) are 99% bound to the thyroxine-binding globulin (TBG) in the blood. This serves to transport the hormones and prevents an early effect of T3. Only about 0.03% T4 and 0.3% T3 are present in the blood unbound and therefore biologically active. The half-life of unbound T4 … Transport in blood | Thyroid hormones
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
Definition The term “pregnancy hormone” primarily refers to human chorionic gonadotropin, HCG or beta-HCG for short. This peptide hormone is produced by part of the placenta and is an important pregnancy-maintaining hormone. In addition, beta-HCG is the hormone measured in standard pregnancy tests. Other important pregnancy hormones are estrogen and progesterone. Pregnancy hormones are those … Pregnancy hormones
What is an HCG diet? The HCG diet is a dietary program developed by a British endocrinologist named Simeons in the 1950s that promises rapid weight loss.The development of the diet took place under ethically questionable circumstances and the promotion of the diet must also be viewed critically. The diet, which was published in 1954, … What is an HCG diet? | Pregnancy hormones
What are the pregnancy hormones like after a miscarriage? After a miscarriage the beta-HCG level drops again within a few weeks, so that it can no longer be detected. A hormonal adjustment of the remaining hormones to the non-pregnant state takes place. This can take several weeks. Normalization of the period may therefore also take … What are the pregnancy hormones like after a miscarriage? | Pregnancy 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
