1. Which organ is stimulated during the alarm phase of the general adaptation syndrome?
A) Hypothalamus
B) Adrenal cortex
C) Pituitary gland
D) Thyroid gland
Correct Answer: Hypothalamus
Rationale: The alarm phase of the general adaptation syndrome is initiated when the hypothalamus
stimulates the sympathetic nervous system and the adrenal medulla. The adrenal cortex is activated
later in the resistance phase, and the pituitary and thyroid glands are not the primary organs
stimulated during the alarm phase. Recognizing this sequence is essential for understanding the stress
response.
2. During an anticipatory response to stress, the reaction from the limbic system is stimulated by
which structure?
A) Adrenal medulla
B) Paraventricular nucleus of the hypothalamus
C) Anterior pituitary
D) Pineal gland
Correct Answer: Paraventricular nucleus of the hypothalamus
Rationale: The paraventricular nucleus of the hypothalamus stimulates the limbic system during an
anticipatory stress response, integrating emotional and cognitive processing. The adrenal medulla
secretes catecholamines, the anterior pituitary releases ACTH, and the pineal gland regulates
circadian rhythms. Understanding this pathway is crucial for stress physiology.
3. Which hormone prompts increased anxiety, vigilance, and arousal during a stress response?
,A) Cortisol
B) Norepinephrine
C) Aldosterone
D) Insulin
Correct Answer: Norepinephrine
Rationale: Norepinephrine, released during the stress response, increases anxiety, vigilance, and
arousal by activating the sympathetic nervous system. Cortisol mobilizes glucose and suppresses
immunity, aldosterone regulates sodium and water balance, and insulin lowers blood glucose.
Recognizing the specific effects of norepinephrine is important.
4. Perceived stress elicits an emotional, anticipatory response that begins in which structure?
A) Adrenal cortex
B) Limbic system
C) Medulla oblongata
D) Spinal cord
Correct Answer: Limbic system
Rationale: The limbic system, including the amygdala and hippocampus, processes the emotional and
anticipatory aspects of perceived stress. The adrenal cortex releases cortisol, the medulla oblongata
regulates vital functions, and the spinal cord transmits reflexes. Understanding the limbic system's
role is fundamental to stress psychology.
5. During a stress response, the helper T1 response is suppressed by which hormone?
A) Cortisol
B) Aldosterone
C) Epinephrine
D) Insulin
, Correct Answer: Cortisol
Rationale: Cortisol suppresses the helper T1 response, shifting the immune system toward a Th2-
dominant state during stress. Aldosterone regulates electrolyte balance, epinephrine mediates acute
stress responses, and insulin regulates glucose. Recognizing cortisol's immunosuppressive effects is
essential.
6. What is the effect that low serum albumin has on the central stress response?
A) Impaired circulation of epinephrine and norepinephrine
B) Enhanced cortisol binding
C) Increased aldosterone secretion
D) Decreased ACTH release
Correct Answer: Impaired circulation of epinephrine and norepinephrine
Rationale: Low serum albumin impairs the binding and circulation of epinephrine and norepinephrine,
affecting the stress response. Albumin does not bind cortisol, aldosterone, or ACTH. Understanding
albumin's role in hormone transport is important for stress pathophysiology.
7. Stress-age syndrome directly results in depressed function of which system?
A) Endocrine system
B) Cardiovascular system
C) Immune system
D) Respiratory system
Correct Answer: Immune system
Rationale: Stress-age syndrome is associated with depressed immune function, leading to increased
susceptibility to infections and impaired wound healing. The endocrine, cardiovascular, and
respiratory systems are affected by stress but are not directly depressed by stress-age syndrome.
Recognizing this association is important for clinical assessment.
