Formation of progesterone: The hormone progesterone (corpus luteum hormone) is formed from cholesterol via pregnenolone in the corpus luteum of the ovaries, in the follicles (follicles in the ovary), in the placenta and in the adrenal cortex. Hormone production in the adrenal gland also takes place in men. The progesterone synthesis in the corpus luteum … Progesterone
Eicosanoids are hormones that act as nerve transmitters (neurotransmitters) and modulators of the immune system. These hormones are also involved in inflammatory processes. Overall, the following types of eicosanoids can be distinguished: Prostaglandins comprise a large number of subgroups, for example prostaglandin D2, prostaglandin E2, prostglandin I2 (prostacyclin) or thorboxanes. Prostaglandins Prostacyclins (part of the … Eicosanoids
The adrenal cortex has a three-layer structure, with each layer producing certain hormones. From the outside to the inside you can find: Zona glomerulosa (“ball rich zone”): Production of mineral corticoids Zona fasciculata (“clustered zone”): Production of glucocorticoids Zona reticulosa (“reticular zone”): Production of androgens These hormones include glucocorticoids, mineral corticoids and androgens. The former … Hormones of the adrenal cortex
Education Formation of oxytocin: The hormone oxytocin is a hormone of the posterior pituitary gland (neurohypophysis), which as a peptide hormone belongs to the neuropeptides. Neuropeptides are hormones produced in nerve cells. Oxytocin is produced in special nuclei (nucleus = nucleus) of the hypothalamus (nucleus paraventricularis, nucleus supraopticus) by nerve cells and is transported from … Oxytocin
What happens in case of oxytocin deficiency? The exact effects of an oxytocin deficiency are the subject of current research, which has not yet been completed. However, there are a number of clues as to what happens when you are oxytocin deficient: In this case, oxytocin is administered as an infusion. Therefore, low levels of … What happens in case of oxytocin deficiency? | Oxytocin
How does oxytocin behave under stress? Stress leads to an alarm reaction of the body, it prepares itself for an argument in the form of fight or flight. For this purpose e.g. : Oxytocin partially has opposite effects. It is therefore an important regulator of stress and can help to contain it. Oxytocin is often … How does oxytocin behave under stress? | Oxytocin
Formation of estrogen: Estrogens as components of the steroid hormones are formed from the hormone androstendione. These hormones are formed in the ovaries (ovaries), placenta, adrenal cortex and testicles (testis). The hormone producing cells in the ovaries are the granulosa and theca cells, in the testis the Leydig intermediate cells. The following estrogen representatives exist: … Estrogens
Definition Noradrenaline is a messenger substance (transmitter) produced naturally in the body, which belongs to the subgroup of catocholamines. It is produced from the neurotransmitter dopamine with the participation of an enzyme (dopamine beta hydroxylase). For this reason, dopamine is also called a precursor of noradrenaline. The production takes place mainly in the adrenal medulla, … Noradrenaline
Noradrenaline receptors The specific receptors for norepinephrine and adrenaline are called adrenoceptors. The two messenger substances act at two different receptor subtypes. On the one hand, the alpha receptors are stimulated and on the other hand the beta receptors are activated. Alpha-1-receptors are mostly located on the walls of the blood vessels, which ensure the … Noradrenaline receptors | Noradrenaline
Dosage Since noradrenaline causes its effects in the body even in small amounts, exact dosage is of crucial importance in the context of therapeutic use in intensive care medicine. A particularly rapid effect is achieved by administering a specific dose intravenously in a single dose (bolus). The stable development of the desired effects is ensured … Dosage | Noradrenaline
Introduction The catecholamines, or catecholamines, belong to the group of hormones with androgenic effects on the cardiovascular system. The catecholamines are so-called sympathomimetic drugs, either produced by the body or artificially synthesized substances, and act on the alpha and beta receptors. Among the catecholamines are Adrenalin Noradrenaline Dopamine Isoprenalin (drug substance) Dobutamine (drug substance) Dopeaxamine … Catecholamines
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
