What is the target of Oxytocin?
|
smooth muscle cells in the breast and uterus
|
|
What is the action of Oxytocin?

milk secretion and increased uterine motility
|
|
What is the target of antidiuretic hormone (ADH) aka vasopressin?
|
smooth muscle around blood vessels and kidneys
|
|
What is the action of antidiuretic hormone (ADH) aka vasopressin?
|
increases blood pressure via contraction of smooth muscle surrounding blood vessels. Also acts to decrease water excretion in the kidneys to retain more water.
|
|
What is the target of follicle-stimulating hormone (FSH)?
|
gonads
|
|
What is the action of follicle-stimulating hormone(FSH)?
|
gamete production in males, ovarian follicle growth in females
|
|
What is the target of Luteinizing hormone (LH)?
|
gonads
|
|
What is the action of Luteinizing hormone (LH)?
|
testicular production of testosterone, ovarian production of estradiol and ovulation
|
|
What is the target of growth hormone (GH)?
|
the liver and organs/tissues (for metabolism)
|
|
What is the action of growth hormone (GH)?
|
stimulates secretion of a growth-promoting peptide hormone known as insulin-like growth factor 1 (IGF-1). Also stimulates protein, carbohydrate, and lipid metabolism
|
|
What is the target of adrenocorticotropic hormone (ACTH)?
|
adrenal cortex
|
|
What is the action of adrenocorticotropic hormone (ACTH)?
|
secretes cortisol
|
|
What is the target of prolactin?
|
breasts
|
|
What is the action of prolactin?
|
breast development and milk production. In males it may facilitate reproductive function. Mediates sexual gratification
|
|
What is the target of thyroxine (T4) and triiodothyronine (T3)?
|
stimulate Na+/K+ ATPases
|
|
What is the action of thyroxine (T4) and triiodothyronine (T3)?
|
increases metabolic rate (by increasing carb. absorption in the small intestine, fatty acid release from adipocytes), affects growth, brain development and function.
|
|
What is the target of calcitonin?
|
bone
|
|
What is the action of calcitonin?
|
decreases plasma Ca concentration by inhibiting osteoclasts and reducing bone resorption in some vertebrates
|
|
What is the target of parathyroid hormone (PTH)?
|
bone, kidneys, and the gastrointestinal tract
|
|
What is the action of parathyroid hormone (PTH)?
|
increases the resorption of bone by osteoclasts, which causes Ca to move into ECF. Stimulates production of 1,25-dihydroxyvitamin D. Increases Ca re-absorption in the kidneys. Decreases phosphate re-absorption in the kidneys.
|
|
What is the target of Cortisol?
|
smooth muscle of blood vessels
|
|
What is the action of Cortisol?
|
organic metabolism, response to stress, immune system inhibition, development
|
|
What is the action of aldosterone?
|
maintains balance of potassium and sodium in the kidneys allowing for the maintenance of extracellular water retention.
|
|
What is the action of insulin?
|
promotes the absorption of blood glucose into cells.
|
|
What is the action of glucagon?
|
promotes increase in blood glucose levels by breaking down glycogen into glucose.

|
What is the action of epinephrine and norepinephrine?
|
stress response; organic metabolism, cardiovascular fxn
|
|
