Most endocrine hormones are circulating hormones, they pass from the secretory cells that make them into interstitial fluid and then into the blood. circulating hormones are carried through the bloodstream to act on distant target cells. Paracrines act as neighboring cells, and autocrines act on the same cells that produced them.
Parathyroid hormone (PTH) is the most important hormone regulating the amount of calcium circulating in the blood. PTH increases blood calcium levels by promoting the release of calcium from bone, enhancing calcium absorption in the intestines, and reducing calcium excretion in the kidneys.
It is possible to have symptoms of hormone deficiency even when the blood levels are normal due to a problem with the hormone receptors or the body's inability to use the hormone effectively. This condition is known as hormone resistance, where the target tissues do not respond properly to the hormone present in the blood, leading to symptoms of deficiency.
Growth hormone stimulates cells to increase in size and divide more rapidly. It enhances the movement of amino acids across cell membranes and speeds the rate at which cells utilize carbohydrates and fats.
growth hormone-releasing hormone from the hypothalamus
Several hormones are produced by the pituitary gland including the endocrine hormones: Thyroid stimulating hormone, human growth hormone, prolactin, and adrenocorticotropic hormone. Gonadotropins: luietinizing hormone and follicle stimulating hormone. And lastly melanocyte stimulating hormones.
Growth hormone
GH (growth hormone)
Thyroid levels are measurements of the thyroid hormones in your body. Low TSH suggests you have too much thyroid hormone circulating. High TSH suggests you don't have enough thyroid hormone circulating.

TRUE
Hormones are regulated by what are called negative feedback mechanisms. When more is needed, more will be released and the opposite is true when there is enough. For example, the secretion of follicle-stimulating hormone decreases as the amount of circulating estrogen increases.
It is possible to have symptoms of hormone deficiency even when the blood levels are normal due to a problem with the hormone receptors or the body's inability to use the hormone effectively. This condition is known as hormone resistance, where the target tissues do not respond properly to the hormone present in the blood, leading to symptoms of deficiency.
Cortisol is largely unbound to plasma proteins in the bloodstream, with about 90% of circulating cortisol being in the free, unbound form.
7.14 reading of TSH means that you do NOT have the correct amount of circulating thyroid hormone. See a Doctor as you most likely are suffering from hypothyroidism. It is not to be taken lightly.
in the wait for a more qualified answer, It is worth note that a quick search in google comes up with a romanian article about excess circulating somatotropic hormone leading to growth retardation. This would be aimed at people around 20 or below.
GlucagonINSULIN causes glucose to be removed from the blood stream by having it stored in the form of Glycogen in muscle and liver cellsGLUCAGON causes glycogen to be broken down from liver and muscle tissue and releases glucose into the blood stream, thus increasing circulating blood glucose levels. The hormone, released by the pancreas, is insulin.
