epinephrine and norepinephrine act as negative feedback regulators of which enzyme?
The hormone that stimulates the release of growth hormone from the anterior pituitary comes from the _____ nucleus of the hypothalamus.
what enzyme catalyzes the conversion of tyrosine to L Dopa?
This adrenergic receptor acts to decrease cAMP levels
the effect of ADH on blood vessels
these trophic cells synthesize follicle stimulating hormone and lutenizing hormone
cortisol is made where?
precursor to ACTH
this hormone is secreted from the post. pituitary in response to a increase in plasma osmolality or a decrease in blood volume
True or False: TSH, FH, and LH are peptide hormones.
ADH V1 receptors are located in the ________
hormone that inhibits the release of growth hormone
the conversion of dopamine to norepinephrine occurs where in the cell?
What neurotransmitter acts on chromaffin cells to increase the synthesis and release of epinephrine and norepinephrine?
this hormone is involved in inducing uterine contractions and stimulation of tactile receptors in the nipples of the lactating breast
which two enzymes act to metabolize epinephrine and norepinephrine?
This adrenergic receptor acts to increase phosphoinositide
QuestionAnswer
percentage of epinephrine or adrenaline made by the adrenal medulla
2 major sites of action for oxytocin
carrier proteins for ADH and oxytocin
Where do the neurons of the nuclei of the hypothalamus terminate?
type of trophic endocrine cell that synthesizes adrenocorticotropic hormone, B endorphin, y-lipotropin
Which two proteins released by the anterior pituitary are peptide hormones?

catalyzes the conversion of dopamine to norepinephrine?
