QuestionAnswer
Thyrotropin releasing hormone can come from which 2 hypothalamic nuclei?
vasopressin or ADH predominantly comes from which nucleus of the hypothalamus?
what enzyme catalyzes the conversion of L Dopa to dopamine?
the conversion of dopamine to norepinephrine occurs where in the cell?
True or False: Norepinephrine and epinephrine required a carrier protein to be transported in the blood.
2 hormones of the posterior pituitary
2 major sites of action for oxytocin
this hormone is secreted from the post. pituitary in response to a increase in plasma osmolality or a decrease in blood volume
what is responsible for transporting catecholamines in and out of chromaffin granules?
hormone that inhibits the release of growth hormone
cortisol is made where?
vasopressin and oxytocin are composed of how many peptides?
on which type of adrenergic receptor will epinephrine illicit a greater response than norepinephrine?
True or False: The parvocellular neurons of the hypothalamic nuclei release releasing or inhibiting hormones in the circulation at the median eminence.
conversion of norepinephrine to epinephrine occurs where in the cell?
which two enzymes act to metabolize epinephrine and norepinephrine?
these trophic cells synthesize follicle stimulating hormone and lutenizing hormone
type of trophic endocrine cell that synthesizes adrenocorticotropic hormone, B endorphin, y-lipotropin
Corticotropin releasing hormone is released from the ______ nucleus of the hypothalamus.
precursor to ACTH
the effect of ADH on blood vessels
Which two proteins released by the anterior pituitary are peptide hormones?
This adrenergic receptor acts to increase phosphoinositide
percentage of epinephrine or adrenaline made by the adrenal medulla
The hormones released by neurons of the hypothalamus act on trophes or endocrine cells of the anterior or posterior pituitary?
what enzyme catalyzes the conversion of tyrosine to L Dopa?
what is the major metabolite of epinephrine and norepinephrine in the urine?
carrier proteins for ADH and oxytocin
