APHY 102 Quiz 1 UPDATED Questions
And CORRECT Answers
Hydrophobic - CORRECT ANSWER- ✔✔1.) Fear of water.
2.) Steroid hormones: testosterone, estrogen.
3.) Fats.
Hydrophilic - CORRECT ANSWER- ✔✔1.) Love of water.
2.) Amino-acid hormones: insulin.
If a hormone is a steroid based hormone, does it bind to a hormone receptor on the cell
surface, or does it diffuse through the plasma membrane? - CORRECT ANSWER- ✔✔It
diffuses through the plasma membrane.
Steroid based hormones - CORRECT ANSWER- ✔✔Bind to internal receptors.
Amino-acid based hormones - CORRECT ANSWER- ✔✔Can't get through so they bind to
cell-surface receptors.
Hormone - CORRECT ANSWER- ✔✔1.) Chemical that travels through the blood.
2.) Has to fit the receptor. Hormones are very specific.
Neural - CORRECT ANSWER- ✔✔Nervous system causes the release of a hormone.
-Ex: Sympathetic nervous system: releases epinephrine.
Hormoral - CORRECT ANSWER- ✔✔Hormone causes the release of another hormone.
-Ex: TSH from the pituitary causes the thyroid to release a hormone.
Humoral - CORRECT ANSWER- ✔✔CHEMICAL, other than a hormone, that causes a
hormone to be released.
-Ex: Glucose in your blood causes insulin to be released from the pancreas.
, Negative Feedback - CORRECT ANSWER- ✔✔Decreases the original stimulus.
Positive Feedback - CORRECT ANSWER- ✔✔Increases the original stimulus.
-Ex: Oxytosin induces childbirth.
Up-Regulation - CORRECT ANSWER- ✔✔Makes more hormones or receptors.
Down-Regulation - CORRECT ANSWER- ✔✔Produce fewer hormones or receptors.
Oxytocin - CORRECT ANSWER- ✔✔is stored in the posterior pituitary and is used in a
positive feedback response to control contractions.
Which of the following is not an endocrine gland?
A.) pancreas
B.) anterior pituitary
C.) posterior pituitary
D.) adrenal cortex - CORRECT ANSWER- ✔✔C.) Posterior pituitary
Synergism - CORRECT ANSWER- ✔✔More than one hormone produces the same effects at
the target cell and their combined effects are amplified.
ACTH - CORRECT ANSWER- ✔✔1.) Produced by the anterior pituitary.
2.) Stimulates the adrenal cortex to release glucocorticoids that help the body to resist
stressors.
Parathyroid hormone/calcitonin - CORRECT ANSWER- ✔✔Antagonists that regulate blood
calcium ion levels.
The adrenal cortex is responsible for producing? - CORRECT ANSWER- ✔✔Cortisol and
aldosterone.
