Hormones Quiz Flashcards
(56 cards)
what is the target organ of ADH
kidney/kidney tubules
What is the role of Gonadocorticoids?
Promote secondary sexual characteristics
what does norephinephrine do
helps to the body prepare for action by increasing alertness, arousal and attention
what does PTH do
Stimulates bone cells to break down bone material (calcium phosphate) and reabsorb calcium into the blood in order to raise blood calcium levels
what is the target organ of oxytocin
smooth muscle in uterus and mammary glands
What does progesterone promote?
Growth of the uterine lining and prevents uterine muscle contractions
what does melatonin do
lets the body know when it’s time to sleep and when to wake up
what hormones are secreted by the anterior pituitary
follice-stimulating hormone (FSH), luitenizing hormone (LH), human growth hormone (hGH), prolactin (PRL), adrenocorticotropic hormone (ACTH), (thyroid stimulating hormone) TSH
what hormones does the posterior pituitary secrete
ADH and oxytocin
What do Mineralocorticoids (e.g., aldosterone) promote?
Reabsorption of sodium and water by the kidneys
What is the function of Calcitonin?
Targets bones and kidneys to lower blood calcium by inhibiting the release of calcium from bone and reabsorption of calcium by kidneys
what does PTH stand for
parathyroid hormonew
What does Adrenocorticotropic hormone (ACTH) do?
Stimulates the adrenal cortex to secrete glucocorticoids
What is the role of estrogen?
Stimulates uterine lining growth and promotes development of the female secondary sexual characteristics
What are the effects of Glucocorticoids (e.g., cortisol)?
Stimulate tissues to raise blood glucose and break down protein
What is the function of Prolactin (PRL)?
Stimulates milk production from the mammary glands
What does glucagon do?
Raises blood glucose levels by converting glycogen to glucose
what does the 4 in T4 mean
the number of iodine molecules in the hormone (4)
What hormone does the Anterior Pituitary secrete for cell division and growth?
Human growth hormone (hGH)
Stimulates cell division, bone and muscle growth, and metabolic functions
what is the target organ of PRL
mammary glands
What hormone is secreted by the Parathyroid?
Parathyroid hormone (PTH)
Raises blood calcium levels by stimulating the bone cells to release calcium, the intestine to absorb calcium from food, and the kidneys to reabsorb calcium
what stimulus do the adrenal glands respond to
stress
What is the function of insulin?
Lowers blood glucose levels and promotes the formation of glycogen in the liver
whats T3
the active form of T4; created by T4 which turns into T3 in the liver and kidneys
