APHY 164 FINAL EXAM QUESTIONS AND
ANSWERS 2025
A hormone is a secreted molecule that is carried in the
bloodstream to where it acts on target cells that bear
specific receptors for that hormone.
- True
- False - .....ANSWER ...✔✔ True
Maxwell has a very high metabolic rate, is skinny, and
has protruding eyes. These are symptoms of
-Hyperthyroidism
-Hypothyroidism
-hyperparathyroidism
-hypoparathyroidism - .....ANSWER ...✔✔
hyperthyroidism
Steroid hormones diffuse through cell membranes, then
bind with receptors, whereas nonsteroid hormones bind
receptors on the target cell membrane.
- True

- False - .....ANSWER ...✔✔ True
The secretion of parathyroid hormone is controlled
primarily by the
-pituitary gland
-concentration of blood calcium
-hypothalamus
-thyroid gland - .....ANSWER ...✔✔ concentration of
blood calcium
As a result of the general stress response, blood
concentrations of epinephrine
-fall and cortisol rise
-and cortisol fall
-rise and cortisol fall
-and cortisol rise - .....ANSWER ...✔✔ and cortisol rise
Choose the example that does not demonstrate a
negative feedback loop of hormonal control
- A hormone that increases blood pressure is released.
Baroreceptors in the arteries sense the pressure change
and stimulate the brainstem to send signals to dilate

blood vessels and counter the effect, decreasing blood
pressure.
- A gland releases hormone that causes free blood
glucose to be collected and stored after a meal. After a
time, the gland detects low free blood glucose and
ceases production of the hormone.
- Pressure receptors sense the movement of a baby
against and through the cervix during labor. They
stimulate the hypothalamus to release a hormone that
causes uterine contractions. This causes more pressure
receptor stimulation, leading to larger releases of the
hormone and stronger, more frequent contractions.
Hormone release ceases after pressure sensations cease.
- .....ANSWER ...✔✔ Pressure receptors sense the
movement of a baby against and through the cervix
during labor. They stimulate the hypothalamus to release
a hormone that causes uterine contractions. This causes
more pressure receptor stimulation, leading to larger
releases of the hormone and stronger, more frequent
contractions. Hormone release ceases after pressure
sensations cease.
Steroid hormones
- Are very soluble in water
- include epinephrine and norepinephrine
-Must interact with membrane receptors because they
are never membrane permeable.

- Are soluble in lipids - .....ANSWER ...✔✔ Are soluble
in lipids
Hormones that the posterior pituitary secretes are
synthesized in the
- Anterior pituitary
- Thalamus
- Hypothalamus
- Posterior pituitary - .....ANSWER ...✔✔ -
Hypothalamus
A person under stress may have a lowered resistance to
infection
-True
-False - .....ANSWER ...✔✔ True
"Endocrine" means
- Hormone synthesis
- Acts upon target cells
- Fast-acting compound
- Internal secretion - .....ANSWER ...✔✔ Internal
secretion
