Exam 34: Stress

Severe stress generally causes adrenaline levels to fall.

List the changes that constitute Selye's stress triad.

Which of the following is not an effect of cortisol?

Anxiety level does not influence allostasis and allostatic load.

Stress is considered a tangible phenomenon.

The brain is not a major target of allostatic load.

Allostasis is the body's final response to stress when normal homeostasis can no longer be maintained.

Define stressor.

Maternal malnutrition and smoking are two common stressors that influence the developing fetus.

Both the stage of resistance and the alarm reaction show very similar responses.

Match each term with its corresponding definition. -Initial stage of the general adaptation syndrome

In response to stress, the adrenal cortex secretes cortisol and aldosterone.

The terms stress triad and general adaptation syndrome are interchangeable.

Because the body feels under attack when experiencing a stress response, the immune system becomes more active and vigilant.

The level of adrenocorticoids in the urine is often used to measure stress.

Identify and briefly describe the three stages in the general adaptation syndrome.

Smoking has been shown to be a stressor that causes a marked rise in the plasma level of hormones from the adrenal cortex.

One of the alarm reaction responses resulting from hypertrophy of the adrenal cortex is an increase in allergic responses.

The Selye stage of exhaustion immediately follows the alarm phase.

Every individual responds somewhat differently to stress.
