True or False: Cortisol is a stress hormone released from the adrenal medulla.

False

True or False: High-stress situations are always physiologically harmful.

False

True or False: Stress rarely cause long-term physiologic disorders.

False

The process of change in an individual in response to altered conditions is called -coping -allostasis -evolution -resistance

allostasis

All of the following stress-induced hormones increase blood glucose except -antidiuretic hormone -cortisol -growth hormone -norepinephrine

antidiuretic hormone

In stressful circumstances, the brain releases______, which may improve mood, reduce pain, and induce sleep. -prolactins -oxytocins -dopamines -endorphins

endorphins

Selye's three phases of the stress response include all of the following except -initiation -resistance -alarm -exhaustion

initiation

Which of the following normally is not secreted in response to stress? -norepinephrine -cortisol -epinephrine -insulin

insulin

Many of the responses to stress are attributed to activation of the sympathetic nervous system and are mediated by -norepinephrine -cortisol -glucagon -ACTH

norepinephrine

Indicators that an individual is experiencing stress include all of the following except -tachycardia -diaphoresis -peripheral vasoconstriction -pupil constriction

pupil constriction

True or False: A coping method is functional if it reduces emotional pain.

True

True or False: Both positive and negative life events can produce stress.

True

True or False: Cortisol decreased the inflammatory response.

True

True or False: Most of the hormones release with stress serve to increase blood glucose.

True

True or False: Norepinephrine and epinephrine are the primary mediators of the alarm phase of the stress response.

True

True or False: Selye calle the "flight-or-flight" response an "alarm reaction" to stress.

True

True or False: Stress can be defined as a threat to homeostasis.

True

Antidiuretic hormone secretion may increase during physiologic stress leading to an increase in -blood sugar -urine output -serum sodium -body fluid volume

body fluid volume

Allostatic adaptation in response to stress may be considered successful when -when hormones are no longer secreted. -heart rate falls below 100 beat/min. -homeostasis is restored. -the stress is no longer present.

homeostasis is restored

The effects of excessive cortisol production include -immune suppression -hypoglycemia -hypovolemia -inflammatory reactions

immune suppression
