"That won't work" says Mr. Skeptic. "How can imagining something nice make my
backache go away?" What is the most direct physiology on which you should base
your response?
A. The limbic system adjusts the activation of the gamma motor neurons.
B. The limbic system adjusts the length of the muscle spindle afferent nerves.
C. The reticular activating system adjusts the activation of the gamma motor neurons.
D. The reticular activating system adjusts the length of the muscle spindle afferent
nerves.

C. The reticular activating system adjusts the activation of the gamma motor
neurons.
Feedback: Good thinking! This is correct physiology that underlies the
musculoskeletal response to stressors.
,Your patient is post-op day 2 after heart surgery. Why might blood sugar checks and
insulin be ordered even if the person has not been previously diagnosed with
diabetes mellitus?
A. Surgery can cause diabetes mellitus.
B. Since they needed heart surgery, they might already have diabetes mellitus, it just
was not diagnosed.
C. Stress from surgery can cause hyperglycemia from increased SNS and cortisol
production.
D. Stress from surgery can cause hypoglycemia from increased SNS and cortisol
production.

C. Stress from surgery can cause hyperglycemia from increased SNS and
cortisol production.
Your colleague wants to be reminded of the physiologic mechanism by which the
brain influences cortisol release. What is the best explanation?
A. The hypothalamus releases CRF; CRF circulates to the posterior pituitary and
causes more ACTH to be released; ACTH circulates to the adrenal cortex and causes
more cortisol to be released.
B. The hypothalamus releases CRF; CRF circulates to the anterior pituitary and causes
more ACTH to be released; ACTH circulates to the adrenal cortex and causes more
cortisol to be released.
C. The hypothalamus releases CRF; CRF circulates to the anterior pituitary and causes
more ACTH to be released; ACTH circulates to the adrenal medulla and causes more
cortisol to be released.
D. The hypothalamus releases CRF; CRF circulates to the posterior pituitary and
causes more ACTH to be released; ACTH circulates to the adrenal medulla and
causes more cortisol to be released.

Feedback: Good thinking! This is an accurate description of cortisol
secretion.
I know we make more cortisol during stress. Remind me how cortisol gets secreted",
says one of your professional colleagues. Choose the best response.
A. The hypothalamus releases corticotropin-releasing factor (CRF), which signals the
anterior pituitary to release adrenocorticotropic hormone (ACTH), which signals the
adrenal cortex to release cortisol.
B. The hypothalamus releases adrenocorticotropic hormone (ACTH), which signals
the anterior pituitary to release corticotropin-releasing factor (CRF), which signals the
adrenal cortex to release cortisol.

Mimi Sad recently lost her beloved poodle, Fifi. She says she is feeling lonely and sad
and spending more time at work, less time at home, and less time with friends. She
reports not sleeping well due to neck tension and a headache. What should you teach
Mimi?
A. You are likely at increased risk for muscle weakness and you should not exercise
vigorously.
B. You are having a normal grief response and you should keep on doing what you're
doing.
C. You are likely at increased risk for low blood sugars and you should check them
