Endocrine System Flashcards
collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep and mood among other things
endocrine system
controls the pituitary gland
hypothalamus
hypothalamus produces (the girl grew dope corn seeds)
thyrotropin-releasing hormone (TRH) gonadotropin-releasing hormone (GnRH) growth hormone-releasing hormone (GHRH) corticotropin-releasing hormone (CRH) somatostatin dopamine
stimulates anterior pituitary gland release of thyroid stimulating hormone (THS)
the master regulator of thyroid gland growth and function
thyrotropin-releasing hormone
stimulates anterior pituitary gland release of follicle stimulating hormone (FSH) and luteinizing hormone (LH)
gonadotropin-releasing hormone
stimulates anterior pituitary gland release of growth hormone (GH)
growth hormone-releasing hormone
stimulates anterior pituitary gland release of adrenocotricotropic hormone (ACTH)
corticotropin-releasing hormone
decreases the amount of released GH and TSH
somatostatin
decreases the amount of released prolactin, activates “reward centers” of brain
dopamine
regulates several physiological processes including stress, growth, reproduction, and lactation
anterior pituitary gland
anterior pituitary gland produces (the lizard ate gross frogs)
thyroid stimulating hormone (TSH) luteinizing hormone (LH) adrenocorticotropic hormone (ACTH) follicle stimulating hormone (FSH) growth hormone (GH)
stimulates thyroxin release from the thyroid gland
thyroid stimulating hormone (TSH)
promotes estrogen production, progesterone production, and ovulation in females; promotes testosterone release in males
luteinizing hormone (LH)
promotes hormone release by the adrenal cortex
adrenocorticotropic hormone (ACTH)
promotes the development of eggs and follicles in females, promotes testosterone production in males
follicle stimulating hormone (FSH)
promotes growth of bones and muscles
growth hormone
promotes milk production in breasts
prolactin
secretes the hormone oxytocin which increases uterine contractions and antidiuretic hormone (ADH) which increases reabsorption of water by the tubules of the kidney
posterior pituitary gland
posterior pituitary gland produces
vasopressin or anti-diuretic hormone (ADH)
oxytocin
maintains blood pressure by increasing kidney fluid retention
vasopressin or anti-diuretic hormone
stimulates contractions of the uterus at birth, stimulates the release of milk when a baby suckles
oxytocin
to regulate your metabolism, which is your body’s ability to break down food and convert it to energy
thyroid gland
thyroid gland produces
thyroxine
calcitonin
increases energy expended during rest periods (basal metabolic rate or BMR)
thyroxine
reduces blood calcium concentration levels
calcitonin
regulating your body’s levels of the minerals calcium and phosphorus
parathyroid gland
parathyroid gland produces
parathyroid hormone (PTH)
increases calcium absorption in the small intestine and increases calcium release rate from bones
parathyroid hormone
adrenal cortex produces
cortisol
aldosterone
has anti-inflammatory properties, regulates the immune system
cortisol
raises level of sodium in blood
aldosterone
pancrease produces
insulin
glucagon
lowers blood sugar levels when necessary
insulin
raises blood sugar levels when necessary
glucagon
adrenal medulla produces
adrenaline (epinephrine) and noradrenaline (norepinephrine)
produces the stress hormones in a fight-or-flight situation
adrenal medulla
increases heart rate and blood sugar levels, relaxes breathing muscles to improve breathing (effect more on heart)
adrenal (epinephrine)
increases heart rate and blood sugar levels, increases blood pressure by narrowing blood vessels (effect more on blood vessels)
noradrenaline (norepinephrine)
pineal gland produces
melatonin
regulates circadian rhythms or sleep cycles
melatonin
ovaries produce
estrogen (estradiol)
primary female sex hormone
development of female reproductive system and secondary characteristics
estrogen
corpus luteum releases
progesterone
regulates the menstrual cycle and crucial for pregnancy
progesterone
testes produces
androgens
causes development of secondary male characteristics ike sperm cell production
androgen
