MULTIPLE CHOICE

 

1. Exhaustion occurs if stress continues when which stage of the general adaptation syndrome is not successful?

a.	Flight or fight	c.	Adaptation
b.	Alarm	d.	Arousal

 

 

ANS:  C

Exhaustion occurs if stress continues and adaptation is not successful, ultimately causing impairment of the immune response, heart failure, and kidney failure, leading to death. The other stages occur before the adaptation stage.

2. Which organ is stimulated during the alarm phase of the general adaptation syndrome (GAS)?

a.	Adrenal cortex	c.	Anterior pituitary
b.	Hypothalamus	d.	Limbic system

 

 

ANS:  B

The alarm phase of the GAS begins when a stressor triggers the actions of the hypothalamus and the sympathetic nervous system (SNS) (see Figure 11-1). The other organs are not stimulated by the alarm phase of GAS.

3. During an anticipatory response to stress, the reaction from the limbic system is stimulated by the:

a.	Retronucleus of the anterior pituitary
b.	Anterior nucleus of the hippocampus
c.	Paraventricular nucleus of the hypothalamus
d.	Prefrontal nucleus of the amygdala

 

 

ANS:  C

The paraventricular nucleus (PVN) of the hypothalamus must be stimulated to cause the limbic system to be stimulated. The other options are not involved in the stimulation of the limbic system.

4. Which hormone prompts increased anxiety, vigilance, and arousal during a stress response?

a.	Norepinephrine
b.	Epinephrine
c.	Cortisol
d.	Adrenocorticotropic hormone (ACTH)

 

 

ANS:  A

Only the release of norepinephrine promotes arousal, increased vigilance, increased anxiety, and other protective emotional responses.

5. Perceived stress elicits an emotional, anticipatory response that begins where?

a.	Prefrontal cortex	c.	Limbic system
b.	Anterior pituitary	d.	Hypothalamus

 

 

ANS:  C

Perceived stressors elicit an anticipatory response that begins in the limbic system of the brain, the only option responsible for emotions and cognition.
