This example wants us to match the hormone to the gland that produces it. And in my experience, this is something you're very likely going to be responsible for, so let's give it a practice. Now we have a memory tool for each one of these glands to help you remember what hormones they produce. Remember, if you don't need the memory tool, don't spend time learning it. But if you need it, it's there for you to help remember things. So let's give it a try. We have a, insulin. What produces insulin? Well, my memory tool there is that the pancreas is covered in glue. Insulin and glucagon are made by the pancreas, so I'm going to put an a on pancreas. Insulin and glucagon work together to regulate the amount of glucose in the blood. Insulin specifically causes your body to lower the amount of blood glucose by producing glycogen. Alright.
Next we have oxytocin. You remember what makes oxytocin? Well, oxytocin, I have the memory tool, a powerful antioxidant. Powerful reminded us that it's the posterior pituitary that makes antidiuretic hormone and oxytocin. So I'm putting my b on posterior pituitary right there. Remember, oxytocin is responsible for stimulating labor contractions and also stimulating the release of milk from the breast. Alright.
Next we have melatonin. Well, melatonin, my memory tool for that. Well, when my kids won't go to bed, I say, hey, go to bed, pinhead. Melatonin is responsible for regulating sleep, and it's the pineal gland that releases it. Now remember that melatonin is responsible for regulating sleep because people sell melatonin as a supplement to help you sleep. So c, melatonin, that is going on the line for pineal gland. There we go. I'm crossing out melatonin.
Next, we have calcitonin. Do you remember what makes calcitonin? Well, my memory tool for this one is that the thyroid and the parathyroid glands together are responsible for calcium and carbs. Carbs being the fact that the thyroid hormone is making T4 and T3, those major metabolic hormones, but it's also making calcitonin. And calcitonin works to lower the amount of calcium in your blood. Though, we should note, it's not really clear how physiologically relevant it is in humans, but it is made by the thyroid gland. So down here we have the thyroid and parathyroid. I'm gonna put a D there.
Now, you probably almost certainly should know the difference between what is made in a thyroid and the parathyroid. They're sort of listed there together. But knowing what the parathyroid makes is very easy to remember. We'll get to that in a second. And the other stuff in that sort of grouping is made by the thyroid. Alright.
Next, we have the growth hormone. You remember what makes growth hormone? Well, growth hormone is the g in that memory tool, flat peg. And that memory tool is to help you remember what the anterior pituitary makes. So here we have anterior pituitary I'm going to put an e on that line. Growth hormone made by the anterior pituitary.
Next, we have progesterone. What makes progesterone? Well, progesterone is one of the sex hormones. It's usually considered one of the female-specific sex hormones, and those sex hormones are going to be made by the gonads. Ovaries in females, testes in males, so I'm going to put an f on the line here for gonads. Now I just do also want to note though, sex hormones are also made in the adrenal cortex. They're made there at lower levels. And if you need to know 1, right, know that sex hormones are made in the gonads. But I am just, you know, for correctness, gonna put an F in parentheses there next to the adrenal glands, because the adrenal glands do produce progesterone, though at a lower level. Alright. Crossing out progesterone.
And then finally, we have parathyroid hormone. Well, parathyroid hormone. Right? I said it's really easy to remember what the parathyroid gland makes. It makes parathyroid hormone. So parathyroid hormone. I'm gonna put a g on this line here. Made by the parathyroid gland. And parathyroid hormone works to raise blood calcium levels by instructing your body to take some calcium out of the bones. Alright.
So that's matching some of our hormones. You should practice matching all of them and remember what makes what. We'll continue looking at this and practice problems to follow. I'll see you there.
