Calcitriol

Formation of calcitriol: The steroid-like hormone calcitriol is formed from the precursor 7-dehydrocholesterol, which in turn is formed from cholesterol. The hormone passes through several stages in the course of its synthesis: First the skin under the influence of UV light, then the liver and finally the kidney. Calciol (cholecalciferol) is formed in the skin, … Calcitriol

Pituitary posterior lobe hormones

Hypophysial rear lobe hormones include oxytocin and antidiuretic hormone (ADH). In the following, ADH– Hormone is discussed, the hormone oxytocin is treated with the reproductive hormones. To the topics: ADH Oxytocin

Kidney hormones

Hormones produced in the kidney include Calcitriol and Erythropoietin This glycoprotein hormone as a hormone of the kidney is produced in the kidney and to a small extent in the liver and brain in about 90% of adults. In the kidney, cells of the blood vessels (capillaries, endothelial cells) are responsible for production. They begin … Kidney hormones

Hormones of the parathyroid gland

The hormone belonging to the parathyroid gland is the parathyroid hormone, a hormone composed of protein (peptide hormone), which is produced in the main cells of the parathyroid glands. The formation and secretion of the parathyroid hormone is regulated by the concentration of calcium in the blood. A low level promotes the supply of parathyroid … Hormones of the parathyroid gland

Reproduction hormones

The reproductive hormones include estrogen, progesterone, androgens, prolactin and oxytocin: Progesterone Prolactin Oestrogen Oxytocin Testosterone The hormone testosterone is responsible for male sex differentiation in human development. Testosterone also initiates the development of secondary sexual characteristics such as physique, hair type, development of the larynx and sebaceous glands. The hormone also regulates the development of … Reproduction hormones

Glucagon

Introduction Glucagon is a hormone of the human body, which has the task to raise the blood sugar level. It therefore acts as an antagonist to the hormone insulin. The hormone of the pancreas, glucagon, also consists of protein (29 amino acids in total). It is produced in the so-called A-cells of Langerhans’ islet cells … Glucagon

ADH

Formation of ADH: ADH, which is also called antidiuretic hormone, adiuretin or vasopressin, is a peptide hormone. This hormone is produced together with the carrier protein neurophysin II in special nuclei of the hypothalamus (nucleus supraopticus, nucleus paraventricularis). The hormone is then stored in the posterior lobe of the pituitary gland, where it is released … ADH

Progesterone

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

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

Hormones of the adrenal cortex

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
