GMS-6419 QUESTION WITH
CORRECT ANSWERS
3 components of endocrine system - correct answer-gland, hormone, target organ/cell
hypothalamus hormones - correct answer-releasing/inhibiting hormones
pituitary gland hormones - correct answer-ACTH, TSH, GH, LH, FSH, PRL, SST, AVP,
OT
thyroid gland hormones - correct answer-T3, T4, CT
parathyroid gland hormones - correct answer-PTH
adrenal gland hormones - correct answer-ALDO, CORT, EPI, NE
pancreas hormones - correct answer-insulin and glucagon
ovary hormones - correct answer-E, P, inhibin
testes hormones - correct answer-T, inhibin
T/F: Target organs can be endocrine glands themselves - correct answer-true
are endocrine hormones secreted into the blood - correct answer-yes
are neurocrine hormones secreted into the blood - correct answer-yes
are paracrine hormones released into the blood - correct answer-no, interstitial fluid
are autocrine hormones released into the blood - correct answer-no, interstitial fluid
what are steroid hormones derived from - correct answer-cholesterol
what are catecholamines derived from - correct answer-tyrosine
what are thyroid hormones derived from - correct answer-tyrosine
, where are peptide hormones made - correct answer-intracellularly (preprohormone in
ribosome, prohormone in ER, hormone in golgi); exception is angiotensin II made
extracellularly
where are steroids made - correct answer-intracellularly
where are catecholamines made - correct answer-adrenal medulla
where are thyroid hormones made - correct answer-thyroid
are peptide hormones hydrophilic - correct answer-yes, circulate in blood free form
are steroid hormones hydrophilic - correct answer-no, need binding protein
are catecholamines hydrophilic - correct answer-yes, circulate in blood free form
are thyroid hormones hydrophilic - correct answer-no, need binding protein
do hydrophilic hormones have a longer or shorter half life than hydrophobic hormones -
correct answer-shorter, they circulate free form; hydrophobic hormones have binding
protein which increases half life
which types of hormones are stored in secretory granules - correct answer-peptides and
catecholamines
which hormones bind on the surface of cells - correct answer-peptides and
catecholamines
which hormones bind intracellularly - correct answer-steroids and thyroid hormones
which hormones are able to diffuse - correct answer-steroids and thyroid hormones
where is the hypothalamus located - correct answer-below the thalamus at the base of
the brain, above the pituitary gland
how are they hypothalamus and pituitary gland connected - correct answer-via the
pituitary stalk/hypophysis/infundibular stalk/neurohypophyseal stalk
physiological actions of anterior pituitary - correct answer-metabolic rate, stress
response, growth, reproduction, lactation
basophil types - correct answer-corticotrophs, thyrotrophs, gonadotrophs
acidophils - correct answer-somatotrophs, lactotrophs
