The arched nucleus is the center of food control and appetite inhibition, if it is stimulated by a tumor, then the person will not be able to eat (loss of appetite).
The axons of the neurons, located in the ventrolateral region of the arcuate nucleus, form what is called the tubero-infundibular pathway that delivers dopamine into the hypothalamic-pituitary portal system.
Pituitary glandular cells that have dopamine receptors will then reduce their release of prolactin, a hormone that has several effects:
*sensation of well-being after orgasm in both males and females (Luca will have this effect).
*growth of the mammary glands and milk production in women.
