For this question, we're talking about the role of prolactin.
00:05
So first of all, prolactin is a hormone, and it is produced in your anterior pituitary gland by lactotrophs in the brain.
00:15
And it is involved in an essential positive feedback loop.
00:21
So this feedback loop is very important in pregnant women and women who just gave birth.
00:28
So for a woman who has a baby, we have.
00:32
Starting with a baby suckling on breast tissue that has an effect part of this feedback loop and it inhibits your prolactin inhibition.
00:44
So it sounds kind of funky, but basically in your hypothalamus, there are these cells that inhibit prolactin from being produced and your baby suckling is going to inhibit the inhibition.
00:56
So eventually it's going to allow prolactin to be secreted.
01:01
And your baby suckling is also going to do another thing.
01:04
It activates your oxytocin production, which is produced in the hypothalamus.
01:11
So because of your baby suckling, that it's going to inhibit prolactin inhibition in your anterior pituitary gland, we are now going to have a production and secretion of prolactin, as well as in your posterior pituitary gland, we are going to have a release of oxytocin.
01:30
And your prolactin is going to have the effect on your breast tissue, and it's going to stimulate milk production.
01:40
It works with oxytocin as well, as oxytocin is going to be the hormone that is going to stimulate the milk ejection...
