QuestionAnswer
cortisol is made where?
True or False: The parvocellular neurons of the hypothalamic nuclei release releasing or inhibiting hormones in the circulation at the median eminence.
Which two proteins released by the anterior pituitary are peptide hormones?
True or False: Norepinephrine and epinephrine required a carrier protein to be transported in the blood.
vasopressin and oxytocin are composed of how many peptides?
Where do the neurons of the nuclei of the hypothalamus terminate?
carrier proteins for ADH and oxytocin
this hormone is secreted from the post. pituitary in response to a increase in plasma osmolality or a decrease in blood volume
oxytocin predominantly comes from which nucleus of the hypothalamus?
The Beta class of adrenergic receptors acts to _____ cAMP levels
what enzyme catalyzes the conversion of tyrosine to L Dopa?
The hormone that stimulates the release of growth hormone from the anterior pituitary comes from the _____ nucleus of the hypothalamus.
True or False: TSH, FH, and LH are peptide hormones.
Corticotropin releasing hormone is released from the ______ nucleus of the hypothalamus.
the effect of ADH on blood vessels
epinephrine and norepinephrine act as negative feedback regulators of which enzyme?
the conversion of dopamine to norepinephrine occurs where in the cell?
Lutenizing hormone releasing hormone acts on which endocrine cell of the anterior pituitary?
Thyrotropin releasing hormone can come from which 2 hypothalamic nuclei?
in stressful situations, cortisol acts on which enzyme?
2 major sites of action for oxytocin
what enzyme catalyzes the conversion of L Dopa to dopamine?
This adrenergic receptor acts to decrease cAMP levels
ADH V2 receptors are located in the ________
catalyzes the conversion of norepinephrine to epinephrine?
The anterior and medial nuclei and the preoptic nucleus of the hypothalamus release which hormone?
percentage of norepinephrine or noreadrenaline made by the adrenal medulla
ADH V1 receptors are located in the ________
QuestionAnswer
under periods of stress, which hormone can stimulate the release of adrenocorticotropin hormone (ACTH)?
The hormones released by neurons of the hypothalamus act on trophes or endocrine cells of the anterior or posterior pituitary?
type of trophic endocrine cell that synthesizes prolactin
catalyzes the conversion of dopamine to norepinephrine?
these trophic cells synthesize follicle stimulating hormone and lutenizing hormone
thyrotrophs synthesize what hormone?
type of trophic endocrine cell that synthesizes adrenocorticotropic hormone, B endorphin, y-lipotropin
which hormone stimulates the release of TSH(mostly) and prolactin from the anterior pituitary?
release of what substance from the arcuate nucleus of the hypothalamus cause the inhibition of the release of prolactin?
What neurotransmitter acts on chromaffin cells to increase the synthesis and release of epinephrine and norepinephrine?
activates myoepithelial cells for release of milk from the breast
hormone that inhibits the release of growth hormone
This adrenergic receptor acts to increase phosphoinositide
2 hormones of the posterior pituitary
this hormone is involved in inducing uterine contractions and stimulation of tactile receptors in the nipples of the lactating breast
percentage of epinephrine or adrenaline made by the adrenal medulla
what is the major metabolite of epinephrine and norepinephrine in the urine?
Hormone that stimulates the release of growth hormone
precursor to ACTH
on which type of adrenergic receptor will epinephrine illicit a greater response than norepinephrine?
vasopressin or ADH predominantly comes from which nucleus of the hypothalamus?
conversion of norepinephrine to epinephrine occurs where in the cell?
somatotrophs synthesize what hormone?
most abundant endocrine cell in the anterior pituitary
