CC 3 Review Questions-Endocrinology (Answers to
Quiz)
Set A
1. Major
difference of a hormone from an enzyme.
A hormone is an initiator of
biochemical reactions, while an enzyme is a catalyst.
2. The
hormone tested in pregnancy test
Human Chorionic Gonadotropic
Hormone (HCG)
3. Hormone
responsible for contraction of uterus during the birthing process.
oxytocin
4. Also
called somatostatin
Growth Hormone Inhibitory Hormone
(GHIH or GHIF)
5. Also
called the master gland
Pituitary gland
6. Function
of FSH
Egg/sperm production
7. Hormone
that helps retain water or maintain water-electrolyte balance
Antidiuretic hormone (ADH),
aldosterone
8. Amino
acid base of thyroid hormones
Tyrosine
9. Anterior
pituitary hormones
FSH, ACTH, FSH, LH, PrL, GH
Set B
1. 3 Hormones produced by thyroid gland
T3, T4, calcitonin
2. Major
carrier protein of thyroid hormones
TBG
3. Where
is acridinium ester used in TFT?
Automated method
4. 3
carrier proteins for thyroid hormones
Albumin, TBPA, TBG
5. Pathway
for T3, T4 secretion.
T3, T4 concentration acts as the
stimulus for increased or decreased TRH secretion. TRH acts on anterior
pituitary to increase or decrease secretion of TSH. TSH stimulates the thyroid
gland to increase or decrease secretion of T3 and T4 returning their
concentrations back to normal and homeostasis is achieved.
6. Solve
for FTI if TT4 = 10 mg/dL, and THBR = 20%
FTI = TT4 X THBR
FTI = 10 X (20/30)
FTI = 6.67 mg/dL
7. Two
methods for T3.T4 test
RIA, EMIT, EQUILIBRIUM DIALYSIS
,ETC.
