hormones Flashcards
Thyrotropin releasing hormone (TRH)
Hypothalmic Hormone
Promotes secretion of thyroid stimulating hormone and prolactin
Corticotropin releasing hormone
Hypothalmic Hormone
Promotes secretion of adrenocorticotropic hormone
Gonadotropin releasing hormone
Hypothalmic Hormone
promotes secretion of follicle stimulating hormone and luteinizing hormone
Growth hormone releasing hormone
Hypothalmic Hormone
promotes secretion of growth hormone
Hypothalmic Hormone
prolactin inhibiting hormone
Hypothalmic Hormone
inhibits secretion of prolactin
somatostatin
Hypothalmic Hormone
inhibits secretion of growth hormone and thyroid stimulating hormone
Follicle Stimulating Hormone Target:
anterior pituatary
Ovaries and Testes
Luteinizing Hormone Target:
anterior pituatary
Ovaries and Testes
Thyroid stimulating Hormone Target:
anterior pituatary
Thyroid Gland
Adrenocorticotropic hormones target
anterior pituatary
Adrenal cortex
Prolactin targets
anterior pituatary
Mammary gland and testes
Growth hormone targets
anterior pituatary
Liver, bones, cartilage, muscle, fats
Antidiuretic hormone target
kidneys
Oxytocin targets
uterus mammary gland
Follicle stimulating hormone effects:
Female: growth of ovarian follicles and secretion of estrogen
Male: sperm production
Luteinizing hormone effects:
Female: ovulation, maintenance of corpus luteum
Male: testosterone secretion
Thyroid stimulating hormone effects:
growth of thyroid, secretion of thyroid hormones
Adrenocorticotropic hormones effects:
growth of adrenal cortex
secretion of glucocorticoid
Prolactin effects:
Female: Milk synthesis
Male: increased LH sensitivity
Growth Hormone effects:
Widespread tissue growth especially in the stated tissue
liver, bones, cartilage, muscle, fat
Antidiuretic effects :
water retention
Oxytocin effects:
labor contraction, milk release, possibly involved in ejaculation, sperm transport, sexual affection and mother infant bonding
Adrenal cortex secretes:
Mineralocorticoids: aldosterone
glucocorticoids: cortisol
gonadocorticoids (androgens): estrogens/testosterone
Aldosterone
stimulates sodium reabsorption and potassium excretion
cortisol
stimulates fat and protein catabolism
stress management
thyroid gland secrets:
Triiodothryonine (T3) thyroxine (T4) and Calcitonin
Hyper secretion of Thyroid hormone (T3 and T4)
Graves disease or hyperthyroidism
Hypo secretion of Thyroid Hormone (T3 and T4)
Cretinism (children)
Myxedema (adults)
Hyper secretion of Growth hormone
Acromegaly (adults)
Gigantism ( children)
Hypo secretion of Growth Hormone
Dwarfism
Hypo secretion of ADH (kidneys)
Diabetes insipidus ( excessive thirst and urination )
Glucagon
blood glucose goes up
insulin
blood glucose goes down
Hypo secretion of insulin
diabetes mellitus
loss of glucose in urine excessive thirst and hunger and urine formation
hyper secretion of aldosterone
aldosteronism
hypertension and edema, excess sodium
abnormal neural muscular function
hypo secretion of aldosterone and cortisol
addison’s disease
decrease in glucose and sodium levels, weight loss, dehydration, hypotension
what organ stimulates blood calcium levels to go up due to hypocalcemia
parathyroid glands stimulates the release of parathyroid hormones to bones, intestines and kidneys. osteoclast to raise blood calcium
what organ stimulates blood calcium levels to go down due to hypercalcemia
thryoid- secretes calcitonin to inhibit osteoclasts. blood calcium goes down.
ADH is also called
Vasopressin because it can vasoconstrict
