Hormones Flashcards
releasing hormones
hormones; promote or inhibit release of various hormones by pituitary gland
thyroid-stimulating hormone (TSH)
anterior pituitary; stimulates thyroid gland
luteinizing hormone (LH)
anterior pituitary; increases production of progesterone (female), testosterone (male), stimulates ovulation
follicle-stimulating hormone (FSH)
anterior pituitary; increases production of estrogen and maturation of ovum (female) and sperm production (male)
ACTH
anterior pituitary; increases secretion of steroid hormones by adrenal gland
prolactin
anterior pituitary; increases milk production
growth hormone (GH) / somatotropin
anterior pituitary; increases body growth, including the growth spurt during puberty
oxytocin
posterior pituitary; controls uterine contractions, milk release, certain aspects of parental behaviour, and sexual pleasure
vasopressin (antidiuretic hormone)
posterior pituitary; constricts blood vessels and raises blood pressure, decreases urine volume
melatonin
pineal gland; increases sleepiness, influences sleep-wake cycle, also has a role in onset of puberty
thyroxine
thyroid gland; increases metabolic rate, growth, and maturation
triiodothyronine
thyroid gland; increases metabolic rate, growth and maturation
parathyroid hormone
parathyroid gland; increases blood calcium and decreases potassium
aldosterone
adrenal cortex; reduces secretion of salts by the kidneys
cortisol, corticosterone
adrenal cortex; stimulates liver to elevate blood sugar, increase metabolism of proteins and fats
epinephrine, norepinephrine
adrenal medulla; similar to effects of sympathetic nervous system
insulin
pancreas; increases entry of glucose to cells and increases storage as fats
glucagon
pancreas; increases conversion of stored fats to blood glucose
estrogens
ovary; promote female sexual characteristics
progesterone
ovary; maintains pregnancy
androgens
testis; promote sperm production, growth of pubic hair, and male sexual characteristics
somatomedins
liver; stimulate growth
renin
kidney; converts a blood protein into angiotensin, which regulates blood pressure and contributes to hypovolemic thirst
thymosin (and others)
thymus; support immune responses
leptin
fat cells; decreases appetite, increases activity, necessary for onset of puberty
