QuestionAnswer
The hormones released by neurons of the hypothalamus act on trophes or endocrine cells of the anterior or posterior pituitary?
percentage of epinephrine or adrenaline made by the adrenal medulla
True or False: The parvocellular neurons of the hypothalamic nuclei release releasing or inhibiting hormones in the circulation at the median eminence.
Corticotropin releasing hormone is released from the ______ nucleus of the hypothalamus.
carrier proteins for ADH and oxytocin
percentage of norepinephrine or noreadrenaline made by the adrenal medulla
what enzyme catalyzes the conversion of L Dopa to dopamine?
epinephrine and norepinephrine act as negative feedback regulators of which enzyme?
This adrenergic receptor acts to decrease cAMP levels
True or False: TSH, FH, and LH are peptide hormones.
ADH V2 receptors are located in the ________
catalyzes the conversion of norepinephrine to epinephrine?
this hormone is secreted from the post. pituitary in response to a increase in plasma osmolality or a decrease in blood volume
Where do the neurons of the nuclei of the hypothalamus terminate?
precursor to ACTH

activates myoepithelial cells for release of milk from the breast
The anterior and medial nuclei and the preoptic nucleus of the hypothalamus release which hormone?
2 hormones of the posterior pituitary
Hormone that stimulates the release of growth hormone
What neurotransmitter acts on chromaffin cells to increase the synthesis and release of epinephrine and norepinephrine?
which hormone stimulates the release of TSH(mostly) and prolactin from the anterior pituitary?
vasopressin and oxytocin are composed of how many peptides?
catalyzes the conversion of dopamine to norepinephrine?
vasopressin or ADH predominantly comes from which nucleus of the hypothalamus?
in stressful situations, cortisol acts on which enzyme?
QuestionAnswer
type of trophic endocrine cell that synthesizes prolactin
cortisol is made where?
under periods of stress, which hormone can stimulate the release of adrenocorticotropin hormone (ACTH)?
