Document Summary
*tropic hormones: stimulate other glands to make & release hormones, usually also triggers the growth of target gland. * humoral stimulus: the control of hormone release in response to changes in the extracellular fluids. * allosteric inhibition: the process by which a regulatory molecule binds to an enzyme in a spot different from the active site for another molecule thus causing a conformational change in the active site, preventing binding of another molecule. *adrenal cortex: the outer portion of the adrenal gland; secretes three classes of steroid hormones: glucocorticoids, mineralocorticoids, and sex hormones (testosterone, estrogen) *adrenal medulla: the inner portion of the adrenal gland; secreted the hormones epinephrine and norepinephrine into the blood in response to sympathetic stimulation. *anterior pituitary: the glandular portion of the pituitary that synthesizes, stores, and secretes growth hormone, ths, acth, fsh, lh, and prolactin. *hypophysiotropic hormones: secreted by the hypothalamus to regulate the secretion of anterior pituitary hormones; releasing/inhibiting hormone.
