(36 cards)
anterior pituitary hormones
FSH follicle-stimulating hormone
LH lutenizing hormone
TSH thyroid-stimulating hormone
ACTH adreno corticotropin hormone
PRL prolactin
GH growth hormone
FSH follicle stimulating hormone (gonadotropin)
target: ovaries and testes
female growth of ovarian follicles and secretion of estrogen
male sperm production
LH lutenizing hormone (gonadotropin)
target: ovaries and testes
female ovulation
male testosterone secretion
TSH thyroid-stimulating hormone
target: thyroid gland
growth of thyroid, secretion of TH thyroid hormone
ACTH adrenocorticotropic hormone
target: adrenal gland
growth of adrenal cortex; secretion of glucorticoids
PRL prolactin
target: mammary glands
milk synthesis
GH growth hormone
target: bone, muscle
widespread tissue growth
thyroid and parathyroid gland hormones
TH thyroid hormones 3+4
calcitonin
parathyroid hormone
TH thyroid hormones 3+4
released by TSH thyroid-stimulating hormone
target: brain, heart, muscles, bone, liver
increases metabolic rate, controls body temperature, HR, brain, muscle, skin, bone
calcitonin
come from parafollicular cells
released by high Ca2+ levels
target: osteoclasts
Ca2+ balance in body, decrease Ca2+ levels; inhibit osteoclast to suppress bone resorption
parathyroid hormone
released by low levels of Ca2+
stimulates osteoclasts and releases Ca2+ for Ca2+ reabsorption; decreases Ca2+ levels
adrenal gland hormones
aldosterone
cortisol
androgens
epinephrine and norepinephrine
aldosterone
from zona glomerulosa
stimulus: decrease in bood pressure
target: epithelial cells and collecting duct in kidney
stimulate Na+ reabsorption and K+ excretion to regulate blood pressure and electrolyte balance
cortisol
from zona fasciulata
stimulus: ACTH
target: liver, muscle, fat, bone, lymphocytes
increase blood glucose levels (for fight or flight)
androgens
from zona reticularis
stimulus: ACTH
target: gonads (tests and ovaries)
development of sexual characteristics
epinephrine and norepinephrine
from adrenal medulla
stimulus: stress response, danger, fear, intense exercise, pain
target: heart, blood vessels, skeletal muscles
increases heart rate and blood pressure by dilating airways
aldosterone location
zona glomerulosa
cortisol location
zona fasciculata
androgens location
zona reticularis
epinephrine and norepinephrine location
adrenal medulla
pancreas gland hormones
insulin
glucagon
somatostatin
insulin
from beta cells
stimulus: sugar levels increase
target: liver, skeletal muscle, fat, heart, brain, vascular endothelium
moves glucose from blood into cells to control blood sugar levels
glucagon
from alpha cells
stimulus: sugar levels drop
target: liver
increase blood glucose levels by causing liver to release glucose
somatostatin
from delta cells
inhibits insulin and glucagon; inhibits release of GH growth hormone
