Are hormones produced by thyroid gland tropic hormones?

Are hormones produced by thyroid gland tropic hormones?

Hormones: A tropic hormone is a hormone secreted by one gland and then stimulates another gland; for example, the pituitary makes TSH, which targets the thyroid and causes the thyroid to make T4 and T3 (liothyronine). The thyroid hormones (T4, T3 (liothyronine)) target other organs (heart, CNS, GI, etc), but not really other glands, so are not really tropic hormones. ...Read more

Hormone (Definition)

A hormone (from greek ὁρμή, "impetus") is a chemical released by a cell or a gland in one part of the body that sends out messages that affect cells in other parts of the organism. Only a little amount of hormone is required to alter cell metabolism. In essence, it is a chemical messenger that transports a signal from ...Read more

What endocrine glands affect human hair growth?

Hair growth: There are many endocrine causes affecting hair growth - so many that it is hard to know where to start. If it is OK with you, I would go online and simply look for "endocrine glands and hair loss". Not every article will be the same but they will be close, particularly if you look for comments from University Medical Faculty. ...Read more

What are the important hormones secreted by pituitary glands?

What are the important hormones secreted by pituitary glands?

Many: The pituitary secretes a number of hormones, all of which are important. Anterior pituitary: follicle stimulating hormone, leutinizing hormone, adrenocorticotropic hormone, thyroid stimulating hormone, prolactin, and growth hormone. Posterior pituitary: oxytocin and antidiuretic hormone. Each serves a different but very important role. ...Read more

How are the adrenal glands which secrete testosterone hormones blocked?

How are the adrenal glands which secrete testosterone hormones blocked?

With medication.: The adrenal glands produce androgenic hormones that can be blocked with medication. Aminoglutethimide, ketoconazole, abiraterone & tak-700 (orteronel) are examples, blocking the synthesis of steroid compounds in the glands. Other essential hormones that are blocked may need to be replaced. Surgical removal of both glands would also eliminate adrenal androgens, but it is not done for this purpose. ...Read more

What are the hormones secreted by parathyroid glands?

What are the hormones secreted by parathyroid glands?

Parathyroid hormone: The parathyroid glands secrete parathyrid hormone. This hormone is important in keeping calcium levels stable in the blood. It does this by removing calcium from bone, activating vitamin d and increasing calcium removal from the urine (so less calcium is lost in the urine). ...Read more

What pituitary hormones cause the adrenal gland to produce mineralocorticoids, glucocorticoids, and androgens and estrogens including pregnenolone?

What pituitary hormones cause the adrenal gland to produce mineralocorticoids, glucocorticoids, and androgens and estrogens including pregnenolone?

Pituitary & steroids: Hi. Pituitary ACTH regulates adrenal cortisol production; it also acutely stimulates aldosterone, but is not the principle regulator. LH principally stimulates gonadal steroid hormone production (both genders make androgens & estrogens, but in opposite dominance). Pregnenolone is early in the steroidogenic pathway in both adrenals and gonads. Good luck! ...Read more

How do the adrenal glands which secrete testosterone hormones get blocked?

What uncommon hormonal disorders (besides acromegaly & pituitary tumors) cause growth hormone overproduction? Do they add height in those over 30?

Height: No, height does not increase in patients over 20-25. I do not quite follow why you think you have growth hormone overproduction. More important - you must see your primary doctor and have her/him evaluate all of your concerns. Please let me know how things develop. ...Read more

What are some hypothalamic hormones that normally stimulate prolactin secretion?

What are some hypothalamic hormones that normally stimulate prolactin secretion?

Inhibitory: Hi. The main hypothalamic influence on prolactin (PRL) secretion is inhibitory, not stimulatory. Dopamine from hypothalamic neurons is inhibitory on anterior pituitary lactotroph cells. There is a stimulatory effect in a fairly sizable fraction of patients from hypothalamic TRH, which is elevated in hypothyroidism. But there is no primary hypothalamic stimulator of PRL secretion. ...Read more

Can you tell me about human endocrine glands and hormones?

Endocrinology: Hi. Hormones are signaling molecules made in one place (their gland) and circulate via the bloodstream to regulate function at other tissues ("target tissues"). Main hormone categories are peptide/protein (e.g., insulin), steroid (e.g., cortisol), biogenic amine (e.g., epinephrine), others. Typically ther is feedback regulation of hormone secretion to keep some process in a normal range. Good luck ...Read more

Pancreas: Endocrine hormones are secreted into the bloodstream to cause effects in other parts of the body. The pancreas secretes Insulin and glucagon to cause these effects. Exocrine hormones are secreted into body cavities with tubes connecting the producing gland into a body cavity. The pancreas secretes a variety of substances into the intestinal tract. ...Read more

Since neurosteroids are made by glial cells and not endocrine glands, are they considered hormones? Is there a name for non-gland-produced hormones?

Hormones: The terminology has not really caught up to the research. "Hormone" usually refers to a substance that is made in one cell/organ but then influences another organ, like thyroxine or cortisol. Neurosteroids act locally in the synapse on neurotransmission, so not a hormone by usual definition. But there are a lot of substances that act locally (eg. prostaglandins, cytokines). What do we call them? ...Read more

What are the endocrine glands for?

Great question!: Endocrine glands (thyroid, adrenal, and pituitary glands, among many others) produce hormones. A hormone is a molecule which is released into the blood to travel to other cells. When the hormone meets a receptor molecule in these other cells, the hormone can change the activity of that cell. For example, Insulin is a hormone which promotes the uptake of glucose in other cells in the body. ...Read more
