Chapter: General Principles of Endocrine Physiology
1. Which statement best reflects hormone receptor upregulation in general
principles of endocrine physiology?
A. It is primarily mediated by transient mechanical effects rather than endocrine
signaling.
B. It represents a process that is independent of receptor regulation and feedback
loops.
C. It is regulated through specific hormonal pathways that coordinate target-organ
responses.
D. It occurs only under pathologic conditions and has no physiologic role.
✅ Correct Answer: C
Rationale: Option C is correct because hormone receptor upregulation depends on
coordinated endocrine signaling, receptor-level transduction, and feedback control
that align secretion with physiologic demand. Option A is too narrow, option B
ignores core endocrine regulation, and option D is incorrect because this
mechanism has normal physiologic relevance.
DIF: Moderate

MSC: Apply mechanisms of hormone receptor upregulation to predict physiologic
and clinical outcomes.

exposure in general principles of endocrine physiology?

signaling.

4. Which statement best reflects positive feedback in ovulation in general
principles of endocrine physiology?
A. It is primarily mediated by transient mechanical effects rather than endocrine
signaling.
B. It represents a process that is independent of receptor regulation and feedback
loops.
C. It is regulated through specific hormonal pathways that coordinate target-organ
responses.
D. It occurs only under pathologic conditions and has no physiologic role.
✅ Correct Answer: C

coordinated endocrine signaling, receptor-level transduction, and feedback control
that align secretion with physiologic demand. Option A is too narrow, option B
ignores core endocrine regulation, and option D is incorrect because this
mechanism has normal physiologic relevance.
