ANSWERS 2026 VERIFIED.
Hypothalamus - ANS axons from here terminate in the posterior pituitary
neurohypophysis - ANS aka the posterior pituitary
antidiuretic hormone - ANS ADH
ADH - ANS hormone abbr. responsible for kidney water retention
ADH - ANS hormone released in response to low blood volume, low blood pressure, and
high ECF osmotic pressure
Oxytocin - ANS hormone that regulates reproductive function (uterine contractions, milk
ejection)
adenohypophysis - ANS aka anterior pituitary
posterior pituitary - ANS gland that produces ADH and oxytocin
1
,anterior pituitary - ANS tropic hormones released by the hypothalamus travel here via
portal system to release many different hormones
tropic - ANS type of hormone that stimulates the release of different hormones from the
anterior pituitary
Prolactin Releasing Hormone - ANS PRH
PRH - ANS stimulates release of prolactin
prolactin inhibiting hormone - ANS PIH
PIH - ANS dopamine, inhibits prolactin release
thyrotropin releasing hormone - ANS TRH
TRH - ANS stimulates TSH release
corticotropin releasing hormone - ANS CRH
corticotropin releasing hormone - ANS CRH
CRH - ANS stimulates release of ACTH
growth hormone releasing hormone - ANS GHRH
2
,GHRH - ANS stimulates GH release
growth hormone inhibiting hormone - ANS GHIH
GHIH - ANS inhibits GH release
gonadotropin releasing hormone - ANS GnRH
GnRH - ANS stimulates LH and FSH release
prolactin - ANS PL
PL - ANS hormone that triggers general reproductive functions, promotes breast
development and milk production, suppresses ovulation during breast-feeding
thyroid stimulating hormone - ANS TSH
TSH - ANS Hormone responsible for thyroid growth, stimulates T3 and T4 hormone
release
adrenocorticotropic hormone - ANS ACTH
ACTH - ANS hormone that promotes glucocorticoid release from adrenal cortex in
response to stress
growth hormone - ANS GH
3
, GH - ANS hormone that promotes IGF-1 release to promote growth, alters protein
synthesis, and carb and lipid metabolism
luteinizing hormone - ANS LH
follicle stimulating hormone - ANS FSH
LH - ANS hormone that stimulates ovulation
FSH - ANS hormone that activates sperm and testosterone production at puberty
pituitary adenoma - ANS tumor on the pituitary gland
acromegaly - ANS gigantism, caused by pituitary adenoma, abnormally high growth rate
pancreas - ANS organ that produces insulin and glucagon
insulin - ANS produced by beta cells in pancreas, promotes glucose uptake from the blood
to decrease blood glucose levels.
glucagon - ANS produced by alpha cells, releases glucose into blood to increase blood
glucose level
type 1 diabetes - ANS disorder in which the body cannot produce enough insulin from
autoimmune beta cell destruction
