QuestionAnswer
which hormone stimulates the release of TSH(mostly) and prolactin from the anterior pituitary?
this hormone is secreted from the post. pituitary in response to a increase in plasma osmolality or a decrease in blood volume
catalyzes the conversion of dopamine to norepinephrine?
catalyzes the conversion of norepinephrine to epinephrine?
what enzyme catalyzes the conversion of tyrosine to L Dopa?
What neurotransmitter acts on chromaffin cells to increase the synthesis and release of epinephrine and norepinephrine?
vasopressin or ADH predominantly comes from which nucleus of the hypothalamus?
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.
release of what substance from the arcuate nucleus of the hypothalamus cause the inhibition of the release of prolactin?
thyrotrophs synthesize what hormone?
the conversion of dopamine to norepinephrine occurs where in the cell?
epinephrine and norepinephrine act as negative feedback regulators of which enzyme?
vasopressin and oxytocin are composed of how many peptides?
conversion of norepinephrine to epinephrine occurs where in the cell?
2 major sites of action for oxytocin
ADH V1 receptors are located in the ________
under periods of stress, which hormone can stimulate the release of adrenocorticotropin hormone (ACTH)?
the effect of ADH on blood vessels
somatotrophs synthesize what hormone?
type of trophic endocrine cell that synthesizes adrenocorticotropic hormone, B endorphin, y-lipotropin
what enzyme catalyzes the conversion of L Dopa to dopamine?
The hormones released by neurons of the hypothalamus act on trophes or endocrine cells of the anterior or posterior pituitary?
activates myoepithelial cells for release of milk from the breast
percentage of epinephrine or adrenaline made by the adrenal medulla
this hormone is involved in inducing uterine contractions and stimulation of tactile receptors in the nipples of the lactating breast
The anterior and medial nuclei and the preoptic nucleus of the hypothalamus release which hormone?
carrier proteins for ADH and oxytocin
QuestionAnswer
