This problem talks to us about the endocrine system, which means we are going to need to think about where hormones come from.
00:10
Specifically, we're going to talk about a part of the endocrine system or a set of hormones that travel through the hypothalamus pituitary axis.
00:20
So here i'm drawing a brain.
00:23
There's a deep region in the brain called the hypothalamus or the below thalamus part.
00:29
The hypothalamus sends chemical messages and also neural messages to a tiny endocrine structure just below that kind of dangles below called the pituitary gland.
00:43
It has two parts, an anterior and a posterior part.
00:47
And the pituitary gland is part of the endocrine system because it sends hormone signals out to organs all over the body, organs and tissues throughout the body.
00:59
In particular, here, just for fun, we will highlight the gonads.
01:03
So we will highlight the ovaries and testes.
01:07
Or if we're going to use the sex neutral term, the gonads.
01:13
Okay, so troic hormones are one of the types of hormones that is secreted along this line.
01:19
So let's look at the hormones that specifically simulate the gonads.
01:26
There are two.
01:27
They are follicle stimulating hormone and lutenizing hormone.
01:44
And depending on if your sex is male or female or whether you are pre or post menopausal, depending on if you're pre puberal or not, your body will have different systems of releasing these hormones that signal the gonads to produce the sex hormones.
02:01
So the sex hormones are testosterone, sometimes just symbolized with a t, and estrogen, just sometimes just symbolized with the e, as well as progesterone and other androgens and other estrogens, a lot of different hormones coming out of our gonadal system...
