MEDSURG II ENDOCRINE QUESTIONS AND
ANSWERS SURE A+
✔✔ what are the 3 endocrine organs? - ✔✔adrenal gland, thyroid gland, and pituitary
gland
✔✔what is the order for the positive negative feedback system? - ✔✔hypothalamus
sends stimulating hormone, pituitary sends releasing hormone, and target organ
secretes hormones
+= hypothalamus senses it is too low, turns on feedback
-= hypothalamus senses too high, shuts off
✔✔primary, secondary, and tertiary organs for feedback - ✔✔tertiary= hypothalamus
secondary= pituitary
primary= organ
✔✔what do we call normal level? - ✔✔"eu"
ex: euthyroid
✔✔5 main functions of the endocrine system - ✔✔1. growth/development
2. reproduction
3. homeostasis
4. responding to emergency needs/stress
5. CNS/brain development
✔✔which secretes stimulating hormones and which secretes releasing hormones? -
✔✔stimulating= pituitary
releasing= hypothalamus
✔✔3 hormones of anterior pituitary - ✔✔growth hormone releasing hormone
, corticotropin release hormone- for ACTH
thyrotropin releasing hormone- for TSH
✔✔what happens from too much or too little ACTH? - ✔✔high: cushing's
low: addison's
✔✔main posterior pituitary hormone - ✔✔ADH
✔✔what would stimulate ADH to be released? - ✔✔low BP, part of RAAS system,
dehydration
✔✔name for whole, front, and back of pituitary - ✔✔hypophysis is whole
adenohypophysis is front
neurohypophysis is back
✔✔where do the following target:
1. GH
2. TSH
3. ACTH
4. ADH - ✔✔1. liver (ICF-1) bone
-insulin growth factor need to get into cells
2. thyroid gland
3. adrenal cortex
4. kidney tubules
✔✔what could cause hyposecretion from glands?
what is an example of suppression of the glands by exogenous hormones? - ✔✔surgery
taking out gland
giving steroids to stop heart transplant rejection, turn on negative feedback,
hypothalamus says no more ARH, no more ACTH= risk is tertiary organ atrophy! harder
to wake up
✔✔what can cause hyperfunction of glands? - ✔✔autoimmune destruction
attack own, can cause hypo or hyper
thyroid
ex: hasimotos hypo
ex: graves hyper
✔✔explain what happens with GH hypersecretion
issue? - ✔✔gigantism, acromegaly (overgrowth of tissue of bones in face, feet, and
head)
