under periods of stress, which hormone can stimulate the release of adrenocorticotropin hormone (ACTH)?
True or False: The parvocellular neurons of the hypothalamic nuclei release releasing or inhibiting hormones in the circulation at the median eminence.
hormone that inhibits the release of growth hormone
in stressful situations, cortisol acts on which enzyme?

percentage of epinephrine or adrenaline made by the adrenal medulla
epinephrine and norepinephrine act as negative feedback regulators of which enzyme?
type of trophic endocrine cell that synthesizes adrenocorticotropic hormone, B endorphin, y-lipotropin
most abundant endocrine cell in the anterior pituitary
vasopressin or ADH predominantly comes from which nucleus of the hypothalamus?
2 hormones of the posterior pituitary
What neurotransmitter acts on chromaffin cells to increase the synthesis and release of epinephrine and norepinephrine?
release of what substance from the arcuate nucleus of the hypothalamus cause the inhibition of the release of prolactin?
True or False: Norepinephrine and epinephrine required a carrier protein to be transported in the blood.
activates myoepithelial cells for release of milk from the breast
