NURS 403 Exam 3 Questions And AnswersThyroid Gland secretes: T3
T4
Calcitonin
Regulated and secreted site for T3, T4: It targets the cells of the body; increases
metabolic rate & increases response to catecholamines
It is secreted by the thyroid gland
High T3, T4= Increased metabolism
Low T3, T4= Decreased metabolism
What does Calcitonin regulate and from what does it secrete? -Answer Calcitonin helps
to decrease osteoclastic activity & reabsorption of calcium in the kidney & intestines
Secreted by thyroid gland
What is released by the parathyroid gland? -Answer parathyroid hormone (PTH)
What does parathyroid hormone regulate and from what does it secrete? -Answer PTH
helps to increase osteoclastic activity and reabsorption of calcium in the intestines and
kidneys
Adrenal medulla secretes - Answer Catecholamines (epinephrine/norepinephrine)
,Where & what is the action of catecholamines? - Answer Mimics action of sympathetic
nervous system (fight or flight response)
Secreted by the adrenal medulla
What does adrenal cortex secrete? - Answer Glucocorticoids and mineralocorticoids
What do glucocorticoids & mineralocorticoids do & where is it secreted? - Answer
Glucocorticoids promote glucogenesis (decreases glucose use), promotes protein
catabolism, & suppresses inflammatory response
Mineralocorticoids stimulates the DCT and collecting ducts of the kidney with
aldosterone *(promotes water reabsorption and potassium excretion)*
Secreted by adrenal cortex
What does the Anterior Pituitary Gland secrete? - Answer Adrenocorticotropic hormone
(ACTH)
Follicle Stimulating hormone (FSH)
Luteinizing hormone (LH)
Growth Hormone (GH)
Thyroid Stimulating Hormone (TSH)
Prolactin
,Melanocyte stimulating hormone (MSH)
What does adrenocorticotropic hormone do & where is it secreted? - Answer It
stimulates the adrenal glands to increase glucocorticoids & mineralocorticoids.
Secreted by the anterior pituitary gland
Where & what does Follicle-Stimulating hormone secrete? - Ans It stimulates the ovaries
to secrete estrogen & stimulate the testes to increase sperm production
Secreted by the anterior pituitary gland
Where & what does Luteinizing Hormone secrete? - Ans It stimulates secretion of
estrogen/progesterone, ovulation & testosterone production

What is the function of Growth Hormone & where is it secreted? - Answer It acts on
tissues & bones, promotes growth of bones/tissues via protein synthesis, fat metabolism
and *insulin antagonism*
Secreted by anterior pituitary gland
What is the function of thyroid stimulating hormone & where is it secreted? - Answer It

melanocytes & Increase pigmentation of skin/hair
Secreted by anterior pituitary gland
What does the posterior pituitary gland secrete? - Ans Vasopressin (ADH)
Oxytocin
What does vasopressin (adh) do & where is it secreted? -Target DCT / collecting ducts in
kidneys to increase water absorption.
Secreted by posterior pituitary gland
What does oxytocin do & where is it secreted? -Target uterus / mammary glands and
stimulates uterine contractions in labor as well as milk production
