Resp Exam Questions With Complete Solutions
_____ are the main male hormones. Correct Answers
Androgens
Adrenocorticotropic hormone (ACTH) triggers the release of
_____ in response to stress. Correct Answers glucocorticoids
After a lipid-soluble hormone is bound to its intracellular
receptor, what does the hormone complex do? Correct Answers
acts as a transcription factor and binds to DNA, activating a
gene
Calcium is actively absorbed in the upper small intestine with
the aid of 1, 25 dihydroxyvitamin D. Correct Answers True
Choose which condition has all of the following symptoms:
hypertension, hyperglycemia, and a "moon face." Correct
Answers Cushing's disease
a patient with Cushing's would have hypertension, increased
blood glucose, and an unusual fat distribution on the face,
known as a "moon face." These symptoms are due to increased
levels of cortisol and can also be seen in patients after long
periods of steroid treatment
From which part of the pituitary are the hypothalamic hormones
(antidiuretic hormone and oxytocin) released? Correct Answers
posterior pituitary
Growth factor hormones, such as insulin, bind to which type of
receptor? Correct Answers tyrosine kinase receptors
, insulin binds to tyrosine kinase receptors and works without a
second messenger.
How are hormones related to the interaction of the nervous
system and muscular system? Correct Answers The nervous
system can control muscle movement by controlling the release
of hormones.
How do nonsteroid hormones differ from steroid hormones?
Correct Answers nonsteroid hormones act via signal
transduction pathways; steroid hormones do not act via signal
transduction pathways
Since they do not enter the cell, nonsteroid hormones act via
signal transduction pathways.
How do releasing hormones travel from the hypothalamus to the
anterior pituitary gland? Correct Answers They are released
near blood vessels (a capillary bed) in the hypothalamus, travel a
short distance, and diffuse out around the cells of the anterior
pituitary.
If a gene is activated by a hormone, what is the most likely chain
of events? Correct Answers A strand of mRNA is transcribed
in the nucleus. It leaves the nucleus for the cytoplasm. The
message is translated into a new protein.
If the level of calcium in the blood falls below the homeostatic
level, which of the following would be true? Correct Answers
In response to stress, which of the following changes would
happen? Correct Answers decreased insulin secretion
