QuestionAnswer
Hypothalamus – corticotropin-releasing hormone (CRH), thyrotropin-releasing hormone (TRH), gonadotropin-releasing hormone (GnRH), growth hormone-releasing hormone (GHRH), growth hormone-inhibiting hormone (somatostatin GHIH), prolactin-inhibiting hormone (PIH), melano
mineralocorticoids produced in zona glomerulosa of adrenal cortex & help control body’s Na & K content
glucocorticoids, androgens, & estrogens produced in zona fasciculate & zona reticularis; hormones produced & secreted by cortex called adrenal steroids/corticosteroids
mineralocortocoids function aldosterone maintains ECF volume, promotes sodium & water reabsorption & K excretion in the kidney tubules
aldosterone secretion is regulated by the renin-angiotensin system, serum K ion concentration, & ACTH
renin-angiotensin system = renin produced by renal arterioles, & its release is triggered by a decrease in ECF volume (can occur from blood loss, Na loss, posture changes)
renin converts angiotensin I to angiotensin II (active form), which then stimulates the secretion of aldosterone, causing the kidneys to reabsorb Na & water to bring the plasma volume & osmolarity back to normal
aldosterone is also secreted when serum K level increases above normal by as little as 0.1mEq/L
glucocorticoids function: cortisol affects carbs, protein, & fat metabolism, body’s response to stress, emotional stability, & immune function
release of glucocorticoids is regulated by ACTH from the AP & indirectly by the release of CRH from the hypothalamus (release of CRH & ACTH is affected by the serum level of free cortisol, sleep-wake cycle, & stress
glucocorticoid release peaks in the morning & reaches lowest level 12h after peak (emotional, chemical, or physical stress increases release of glucocorticoids)
adrenal medullary hormones (catecholamines)
function: adrenal medulla secretes norepinephrine (15%) & epinephrine (85%)
norepinephrine acts mainly on alpha-adrenergic receptors
epinephrine most often stimulates beta-adrenergic receptors

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
