QuestionAnswer
carrier proteins for ADH and oxytocin
Thyrotropin releasing hormone can come from which 2 hypothalamic nuclei?
this hormone is involved in inducing uterine contractions and stimulation of tactile receptors in the nipples of the lactating breast
This adrenergic receptor acts to increase phosphoinositide
Where do the neurons of the nuclei of the hypothalamus terminate?
percentage of epinephrine or adrenaline made by the adrenal medulla
catalyzes the conversion of dopamine to norepinephrine?
ADH V2 receptors are located in the ________
The Beta class of adrenergic receptors acts to _____ cAMP levels
conversion of norepinephrine to epinephrine occurs where in the cell?
2 hormones of the posterior pituitary
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: Norepinephrine and epinephrine required a carrier protein to be transported in the blood.
epinephrine and norepinephrine act as negative feedback regulators of which enzyme?
oxytocin predominantly comes from which nucleus of the hypothalamus?
what enzyme catalyzes the conversion of tyrosine to L Dopa?
precursor to ACTH
vasopressin or ADH predominantly comes from which nucleus of the hypothalamus?
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?
under periods of stress, which hormone can stimulate the release of adrenocorticotropin hormone (ACTH)?
Hormone that stimulates the release of growth hormone
the conversion of dopamine to norepinephrine occurs where in the cell?
thyrotrophs synthesize what hormone?
the effect of ADH on blood vessels
most abundant endocrine cell in the anterior pituitary
True or False: The parvocellular neurons of the hypothalamic nuclei release releasing or inhibiting hormones in the circulation at the median eminence.
The anterior and medial nuclei and the preoptic nucleus of the hypothalamus release which hormone?
QuestionAnswer
what is responsible for transporting catecholamines in and out of chromaffin granules?
somatotrophs synthesize what hormone?
what enzyme catalyzes the conversion of L Dopa to dopamine?
This adrenergic receptor acts to decrease cAMP levels
Lutenizing hormone releasing hormone acts on which endocrine cell of the anterior pituitary?
these trophic cells synthesize follicle stimulating hormone and lutenizing hormone
2 major sites of action for oxytocin
on which type of adrenergic receptor will epinephrine illicit a greater response than norepinephrine?
activates myoepithelial cells for release of milk from the breast
cortisol is made where?
type of trophic endocrine cell that synthesizes prolactin
catalyzes the conversion of norepinephrine to epinephrine?
percentage of norepinephrine or noreadrenaline made by the adrenal medulla

in stressful situations, cortisol acts on which enzyme?
ADH V1 receptors are located in the ________
what is the major metabolite of epinephrine and norepinephrine in the urine?
release of what substance from the arcuate nucleus of the hypothalamus cause the inhibition of the release of prolactin?
type of trophic endocrine cell that synthesizes adrenocorticotropic hormone, B endorphin, y-lipotropin

hormone that inhibits the release of growth hormone
