What is the target of Gonadotropin-releasing hormone (GnRH)?
anterior pituitary
What is the action of Gonadotropin-releasing hormone (GnRH)?
stimulates secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH)
What is the target of Growth hormone-releasing hormone (GHRH)
anterior pituitary
What is the action of Growth hormone-releasing hormone (GHRH)
secretion of growth hormone (somatotropin)
What is the target of somatostatin?
anterior pituitary
What is the action of somatostatin?
inhibits secretion of growth hormone (somatotropin)
What is the target of Thyrotropin-releasing hormone (TRH)?
anterior pituitary
What is the action of Thyrotropin-releasing hormone (TRH)?
stimulates secretion of thyroid-stimulating hormone (TSH)
What is the target of Dopamine (DA)?
anterior pituitary
What is the action of Dopamine (DA)?
inhibits secretion of prolactin (PRL)
What is the target of Corticotropin-releasing hormone (CRH)?
anterior pituitary
What is the action of Corticotropin-releasing hormone (CRH)?
stimulates secretion of adrenocorticotropic hormone (ACTH)
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 target of epinephrine and norepinephrine?
sympathetic nervous system
What is the action of epinephrine and norepinephrine?
stress response; organic metabolism, cardiovascular fxn
What is the target of testosterone?
reproductive system
What is the action of testosterone?
development and expression of secondary sex characteristics, gamete development, sex drive
What is the target of estrogen?
ovarian follicles
What is the action of estrogen?
multiple effects on the reproductive system, secondary sex characteristics in females
What is the target of progesterone?
reproductive system
What is the action of progesterone?
supports pregnancy and endometrium
What is the target of atrial-natriuretic peptide (ANP)?
kidneys
What is the action of atrial-natriuretic peptide (ANP)?
reduces blood pressure via sodium secretion in the kidneys and reducing water volume in blood, which causes a decrease in blood volume
What is the action of insulin-like growth factor 1 (IGF-1)?
regulates growth of bone and other tissues, cell division
What is the action of insulin-like growth factor 1 (IGF-1)?
regulates growth of bone and other tissues, cell division
