I understnding the Hypothalamus

[biferi]

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.
