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

But the ultimate regulation is from that pituitary gland.

S Pituitary really does do a whole lot X.X

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

Benign tumor.

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

Tumor, was it?

The tumor in your leg is not consistent with a benign tumor.

So here's a tumor.

A brain tumor. Nice!

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

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

Is it a brain tumor?

In cancer research experiments, tumor cells are sometimes injected into an experimental animal to establish a tumor.

We think the entire tumor is out.

Can you tell where the tumor is?

In this case, a one centimeter tumor.

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

And that's when we call it a tumor.

Maybe even find a tumor, in some cases.

It's not brain tumor, but I have headache.

Tumor cells can travel through the blood vessels.

A November 2009 study in mice shows that activating the tumor suppressor p53 with a new drug, nutlin 3, may slow tumor growth.

But the MBI image shows that tumor much more clearly, as well as a second tumor, which profoundly influence that patient's surgical options.

like this kidney tumor, so that you can exactly see where the boundary is between the kidney tumor and the kidney you want to leave behind, or the liver tumor and the liver you want to leave behind.

On microscopic inspection, the tumor cells are readily recognized.

In rare cases, no primary tumor can be discerned.

What about the nerve that's going into this tumor?

We have found that you have a cancerous tumor

If you can find a tumor when it's less than a centimeter, survival exceeds 90 percent, but drops off rapidly as tumor size increases.

In this context papilla refers to the projection created by the tumor, not a tumor on an already existing papilla (such as the nipple).

If you can find a tumor when it's less than a centimeter, survival exceeds 90 percent, but drops off rapidly as tumor size increases.

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

So, in the chicken you get a tumor, in the embryo you don't, you dissociate, you put it in a dish, you get another tumor.

And, like a tumor, fat grows when blood vessels grow.

This condition usually occurs in the absence of a tumor.

But what about the part that goes into the tumor?

And like a tumor, fat grows when blood vessels grow.

So the term neoplasm and tumor are often used interchangeably.

And look at how the tumor sizes plummeted in between.

We can light up tumors like this kidney tumor, so that you can exactly see where the boundary is between the kidney tumor and the kidney you want to leave behind, or the liver tumor and the liver you want to leave behind.

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

If the imbalance is taking place in the pituitary glands, growth disorders are possible and will require treatment of a growth hormone.

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

And now, boom, the tumor labels itself and it gets fluorescent.
