Hello student, the question is regarding four major hormonal axes.
00:06
Those are hps x's, hbtxs, hpaxs, hpaxs, hpaxs, and hbgxs.
00:13
So what is hpsxis? it means h4, hypothalamo, pituitary, somatotropic, xs, okay? so, hypothalamo, let us write, hypothalamo.
00:27
That means hypothalamus is involved here.
00:29
And from hypothalamus, ghrh is secretate.
00:35
H .r .h means growth hormone, that means growth hormone releasing factor, releasing hormone, okay? hypothalamolome, then pituitary.
00:51
Then comes pituitary gland.
00:55
This ghrh or gh growth hormone releasing hormone stimulates pituitary to make the next hormone, that is, the g h, okay? g h.
01:13
So let us just underline, double underlining the hormones, okay? g .h means growth hormone.
01:23
Now these growth hormones are secreted with the help of pituitary somatotroft cells.
01:31
Now this growth hormone then stimulates some tissues like liver.
01:38
So somatopropic axis, it means.
01:43
Okay hbs axis this is the full form now this growth hormone then stimulates some tissues like liver to produce insulin like growth factor one that means igf 1 that is also known as somatomatin 1 okay this igf 1 then works on target tissues that means the somatic cells of our body and which has effect on growth and development so it helps us grow, okay? and mainly it helps increasing height in children.
02:31
So this is the hps axis.
02:36
Now let's move on to the hpt, that means hypothalamopitory thyroid axis.
02:44
Now, this hypothalamo or hypothalamus, what does it do? we can just draw an arrow from the h.
02:54
That means hypothalamus, it releases trh.
02:58
What is trh? trh is a hormone that is also known as thiodotropin releasing hormone.
03:14
When this thytotropine releasing hormone or trh works on pituitary, okay, works on p.
03:20
Now, as pituitary stimulated, t .s .h is produced...
