QuestionAnswer
on which type of adrenergic receptor will epinephrine illicit a greater response than norepinephrine?
percentage of norepinephrine or noreadrenaline made by the adrenal medulla
what is the major metabolite of epinephrine and norepinephrine in the urine?
True or False: TSH, FH, and LH are peptide hormones.
what enzyme catalyzes the conversion of L Dopa to dopamine?
What neurotransmitter acts on chromaffin cells to increase the synthesis and release of epinephrine and norepinephrine?

what is responsible for transporting catecholamines in and out of chromaffin granules?
Lutenizing hormone releasing hormone acts on which endocrine cell of the anterior pituitary?
vasopressin and oxytocin are composed of how many peptides?
cortisol is made where?
this hormone is secreted from the post. pituitary in response to a increase in plasma osmolality or a decrease in blood volume
under periods of stress, which hormone can stimulate the release of adrenocorticotropin hormone (ACTH)?
precursor to ACTH
This adrenergic receptor acts to decrease cAMP levels
catalyzes the conversion of norepinephrine to epinephrine?
The hormone that stimulates the release of growth hormone from the anterior pituitary comes from the _____ nucleus of the hypothalamus.

which hormone stimulates the release of TSH(mostly) and prolactin from the anterior pituitary?
The Beta class of adrenergic receptors acts to _____ cAMP levels
Where do the neurons of the nuclei of the hypothalamus terminate?
