Practice questions
- According to the cited review of endocrine cAMP signaling, which reaction inactivates cAMP?
- Which statement best describes the role of cAMP in endocrine physiology in the cited review?
- A hypothetical endocrine-cell perturbation selectively reduces PDE activity while cAMP production is unchanged. Based on PDE function, what is the most direct expected effect?
- Which pathway is specifically described as central to the development and physiology of endocrine tissues?
- A review notes that disruption of PDEs has been suggested to contribute to endocrine disease. Which interpretation most accurately reflects that evidence?
- In the circadian regulation of hypothalamic and pituitary endocrine physiology, which structure is described as providing timing cues to local clocks?
- What does temporal gating of hypothalamic and pituitary hormone release mean in the context of the cited review?
- Which set of processes is identified in the circadian review as potentially influenced by endogenous clocks?
- A researcher finds that a hormone's secretion varies with time. Which interpretation is most consistent with the cited circadian review?
- Why may circadian timing be relevant when considering endocrine treatment schedules?
- Which molecular structures support junctional cell-to-cell communication in endocrine tissues?
- What is the relationship between connexin hemichannels and gap junctions?
- Which statement about pannexin channels is best supported by the cited review?
- A physiological stimulus changes the degree of gap-junction-mediated coupling in an endocrine tissue. Which pattern of change is described in the cited review?
- Which group of tissues is explicitly included in the review of connexins and pannexins in endocrine physiology?
- In foals, when does much of endocrine maturation occur according to the cited review?
- Which developmental role of cortisol is described in the review of foal endocrine physiology?
- Which set of systems is described as requiring thyroid hormones for function during foal development?
- Which conclusion about cortisol and thyroid hormones in the developing foal is most consistent with the cited review?
- A review of endocrine energy homeostasis in foals lists several additional factors beyond cortisol and thyroid hormones. Which option contains only factors named in that review?
- According to the cited vitamin D review, what net daily calcium absorption is described as necessary to offset typical obligatory losses and protect the skeleton?
- At which serum 25-hydroxyvitamin D3 concentration does the cited review describe regulation of intestinal calcium absorption as optimal?
- A serum result is being compared with the vitamin D measure discussed in the cited review. Which analyte is specified?
- A researcher wants to test the cited review's claim about vitamin D status and calcium absorption. Which outcome is most directly relevant?
- A review of suspected endocrine pathology in newborn infants emphasizes that normal hormonal function is dynamic. What is the practical implication stated in the review?
