PHARMACOLOGY (Endo) PROBLEM SETS QUESTIONS AND ANSWERS
COMPLETE RATED A CHAMBERLAIN UNIVERSITY
Problem Set 1: Endocrine and Pituitary
1. The majority of hormones secreted by
the hypothalamus affect what structure?
A. Kidneys
B. Pineal gland
C. Anterior pituitary
D. Posterior pituitary
E. Liver
2. The pineal gland
secretes what hormone?
A. Oxytocin
B. ADH
C. GnRH
D. Erythropoietin
E. Melatonin
answer is C
- 8 hormones produced and released by the hypothalamus
- 6 of them regulate the anterior pituitary
- 2 are released into capillaries in the posterior pituitary
- out of the 6 of the anterior pituitary, 4 of them
stimulate it (TRH, CRH, GnRH, and GHRH) and 2 of
them inhibit it (PIH and somatostatin)
D is wrong
- 2 of the 8 regulate the posterior pituitary which
include oxytocin and ADH
answer is E
- pineal gland - back of the diencephalon
- secretes melatonin - has the primary control of our
circadian rhythm
A and B are wrong
- ADH and oxytocin are released by the posterior
pituitary
C is wrong
- GnrH - released by the anterior pituitary and stimulates LH and FSH release
- if you inhibit GnRH then you do not get the release
of LH or FSH and then you not get estrogen or
progesterone then you will get hypogonadism
- hypogonadism and infertility are the result of inhibition of GnRH release
D is wrong
- erythropoietin is released by the kidneys (85%) and
the liver (15%)
