AI Thread Summary
The discussion centers on the relationship between the hypothalamus and the pituitary gland in hormone regulation. The hypothalamus controls various bodily functions, including sex drive and appetite, by signaling the pituitary gland through hormones. Specifically, the hypothalamus releases growth-hormone-releasing factor (GHRF), which prompts the pituitary gland to secrete growth hormone (GH). This interaction highlights the hypothalamus's role in initiating hormonal responses that influence growth and other physiological processes.

I know the Hypothalamus controls Hormones for Sex Drive and Eating and so on.

And I know it is conected to the Pituitary Gland through a Stalk.

Am I right when the Hypothalamus puts out Harmones it first sends a signal to the Gland it wants to put out the Harmone?

So for Groth Harmone to be put out the Hypothalamus will send a signal to the Pituitary Gland to let it put out the Harmone?

Hi biferi,

hypothalamus' ability to secrete hormones is only a part of the system through which it influences and control various body processes.

The signal you mentioned is GHRF (growth-hormone-releasing factor, which is a hormone itself), which stimulates adenohypophysis to secrete GH.

Thread 'Did they discover another descendant of homo erectus?'

The study provides critical new insights into the African Humid Period, a time between 14,500 and 5,000 years ago when the Sahara desert was a green savanna, rich in water bodies that facilitated human habitation and the spread of pastoralism. Later aridification turned this region into the world's largest desert. Due to the extreme aridity of the region today, DNA preservation is poor, making this pioneering ancient DNA study all the more significant. Genomic analyses reveal that the...

Thread 'Warning of new opiod drug (nitazene) on the streets: Question re strength...'

Whenever these opiods are mentioned they usually mention that e.g. fentanyl is "50 times stronger than heroin" and "100 times stronger than morphine". Now it's nitazene which the public is told is everything from "much stronger than heroin" and "200 times stronger than fentany"! Do these numbers make sense at all? How do they arrive at them? Kill thousands of mice? En passant: nitazene have already been found in both Oxycontin pills and in street "heroin" here, so Naloxone is more...
