Alright.
In this video, we are going to go over the organs and glands that release hormones in
the body, and we will briefly cover which hormones they produce.
In the subsequent videos we will go into more details about each of those key hormones.
So there are dozens of hormones in the body, and we're not going to cover them all, but
we are going to cover the ones that I think are most important for you to know as a nurse
or a nursing student so that you can better understand the disorders of the endocrine
system.
So if you are following along with cards, the information I'm going to talk about in
this video will be on cards two through four, and I'm now going to bring up an illustration
that is on card four, to talk about all of those organs and hormones.
Alright.
So let's talk about the organs and glands of the endocrine system, and what hormones
they produce.
So starting with the hypothalamus, the hypothalamus is located in the brain and it produces four
key hormones that I'd be familiar with.
One is corticotropin-releasing hormone.
Then we have thyroid-releasing hormone, growth hormone-releasing hormone, and gonadotropin-releasing
hormone.
You notice that all four of these end in that releasing hormone.
And then if you look at the first letter of each of these hormones, we have C, T, G, G.
and my little mnemonic I use to help me recall these hormones is Cutthroat good game.
That was a Cutthroat game, but good game anyway, and that's just my silly way to remember these
hormones.
Then, moving on to the pituitary gland.
The pituitary gland is also located in the brain.
Some hormones are released from the anterior pituitary gland and some hormones are released
from the posterior pituitary gland.
So the hormones released from the anterior pituitary gland include thyroid-stimulating
hormone, prolactin, follicle-stimulating hormone, luteinizing hormone, adrenocorticotropic hormone,
and growth hormone.
And then the two key hormones released from the posterior pituitary gland include ADH,
which is anti-diuretic hormone, and oxytocin.
So the way I remember these six key hormones from the anterior pituitary gland is I look
at the first letter of each, which is T-P F-L-A-G, which kind of looks like TP FLAG.
So I think about the anterior pituitary gland surrendering or giving up hormones and flying
a white TP flag.
So that's my little inappropriate potty-humor way of remembering what hormones are released
by the anterior pituitary gland.
Okay.
Moving on to the thyroid gland in the neck.
The thyroid gland produces T3, which is triiodothyronine; T4, which is thyroxine; and calcitonin.
So from now on, I'm going to refer to those as T3 and T4, so I don't have to try to pronounce
triiodothyronine anymore.
Okay.
And then we are going to move on to the parathyroid glands.
So we have four parathyroid glands located right next to the thyroid gland, and they
produce parathyroid hormone, or PTH.
Then we go down to the adrenal glands.
The adrenal glands rest on top of the kidneys.
And some hormones are released from the adrenal cortex, which is the outer layer of the adrenal
gland, and then some hormones are released from the adrenal medulla, which is the inside
of the adrenal gland.
So the hormones released by the adrenal cortex include aldosterone, cortisol, and androgens.
And then from the adrenal medulla, the hormones produced there include epinephrine and norepinephrine.
Then we have the pancreas, which is situated behind the stomach.
The pancreas produces insulin and glucagon.
The testes is another endocrine gland.
It produces testosterone.
And then the ovaries produce estrogen and progesterone.
Okay.
In our next video, we will get into specific hormones, what their functions are in the
body, and what controls release of those hormones.
So stay tuned!
