The pituitary gland is called the master gland because from the pituitary gland we make hormones that work on yet other organs.

Hypothalamus in the midbrain, pituitary gland nestled close by, thyroid, here, pancreas, here, adrenals, here, ovaries, here.

But the ultimate regulation is from that pituitary gland.

N Also out of the pituitary we make luteinizing hormone and follicle stimulating hormone.

Those are the two main circulating thyroid hormones.

So, I'll give you an example, one of the hormones made by the pituitary is called the thyroid stimulating hormone, or the TSH.

S Pituitary really does do a whole lot X.X

It gives rise to the anterior pituitary (adenohypophysis), a part of the endocrine system.

Drugs that block the effects of dopamine at the pituitary or deplete dopamine stores in the brain may cause the pituitary to secrete prolactin.

The other hormones, some of the major ones, the pituitary, in addition to making TSH, it makes a hormone called ACTH, adrenocorticotrophic hormone, which acts on the adrenal cortex, and the adrenal is the gland that sits right on top of the kidney, and the outer layers of the adrenal gland are the adrenal cortex, and those are stimulated by ACTH.

And after it leaves the pituitary, it goes into the circulation, and it acts on the thyroid where there are high receptors for TSH on the surface of the thyroid cells, and it stimulates the thyroid gland to make thyroid hormone, typically thyroxine (T4), or triiodothyronine (T3).

N

N That's right. And we'll talk later about feedback loops, because how does the pituitary know when to stop making TSH?

Synthetic TRH is also used by physicians as a test of TSH reserve in the pituitary gland as it should stimulate the release of TSH and prolactin from this gland.

This triggers the pituitary gland, a pea sized gland found at the base of the brain, to release adrenocorticotropic hormone which then stimulates the adrenal gland sitting on top of the kidneys to release cortisol, the major stress hormone.

Alcohol also limits the production of vasopressin (ADH) from the hypothalamus and the secretion of this hormone from the posterior pituitary gland.

So, it's critical to maintain just the right amount of all of these hormones, and thyroid hormones is a good example.

So now we're gonna work our way down a bit, we talked about the thyroid gland making the thyroid hormones, and when you get to the pancreas, which is that yellow structure right in the middle, inside of the pancreas there are small islands called the islets of Langerhans, and the islets within the pancreas make endocrine hormones, like insulin and glucagon,

N Insulin is key, but it doesn't come from the pituitary.

In 1985, biosynthetic human growth hormone replaced pituitary derived human growth hormone for therapeutic use in the U.S. and elsewhere.

A young mistress' hormones can temporarily revive an old man.

Well, there are two other hormones that are derived from the anterior pituitary, and those are the Growth Hormone (GH) which is critical for optimal growth (e.g., of long bones)

It was previously thought that particular types of pituitary tumors were more prone to apoplexy than others, but this has not been confirmed.

What you got, the mumps?

A gland is an organ in an animal's body that synthesizes a substance such as hormones for release into the bloodstream (endocrine gland) or into cavities inside the body or its outer surface (exocrine gland).

Hormone are the law of the land. No hormones means no milk.

So BPA mimics the body's own hormones and causes neurological and reproductive problems.

Causes There are several causes of hyperthyroidism.

The gonad is the organ that makes gametes.

The normal example, let's take the human mammary gland.

The principle disease here is goitre.

like cortisol, adrenaline and dopamine, increase the level of mood enhancing hormones like endorphins, and reduce overall blood pressure.

like the insulin and the IGF hormones and the TOR pathway, they're essential.

TSH it makes, if the levels are too low, it will stimulate production of TSH to make the thyroid gland make more thyroid hormone.

If you're about to get chomped on by a bear, your stress hormones better kick your butt into gear.

Thyroid hormone is critical to normal function of cells.

These signs disappear with treatment of the hyperthyroidism.

Too many chemicals, pesticides, hormones, monoculture, we don't want giant fields of the same thing, that's wrong.

Lack of dietary iodine causes growth stimulation in the thyroid, and some studies suggest that iodine deficiency increases the risk of radiation induced thyroid cancer.

When there is too much thyroid hormone, the TSH will be low.

Androgens are important in male sexual development around birth and at puberty.

But, how does stress cause this?

Some species can spin silk from glands in their mouth.

And those three hormones are the main hormones made by the adrenal cortex.

The exact mechanisms are, however, not convincingly clarified, although removal of the thymus gland (thymectomy) in MG patients without a thymus neoplasm often have positive results.
