Pathophys Ch 12

Front 1

Souce and effect of Norepinephrine when its secreted during stress?

Back 1

From: the SNS and from the adrenal medulla
Causes:
1. Gen. vasoconstriction
2. Increased BP

Front 2

Souce and effect of Epinephrine when its secreted during stress?

Back 2

From: Adrenal medulla
Causes:
1. Increased heart rate
2. Gen. vasoconstriction resulting in:
A) Increased BP
B) Vasodialation in skeletal muscle
C) Bronchodialation
D) Increased blood glucose

Front 3

Souce and effect of ACTH when its secreted during stress?

Back 3

From: Anterior Pituitary
Causes: stimulates the adrenal cortex

Front 4

Souce and effect of Cortisol when its secreted during stress?

Back 4

From: Adrenal medulla
Causes:
1. Increased stability in the cardiovascular system
2. Inhances the effects of the catecholamines
3, elevates blood glucose
4. Reduces the inflammatory and immune respones
5. Stimulates the CNS

Front 5

Souce and effect of Aldosterone when its secreted during stress?

Back 5

From: Adrenal cortex
Causes: Increases the reabsorption of NA+ and H2O-increasing BP

Front 6

Souce and effect of ADH when its secreted during stress?

Back 6

From: Posterior pituitary
Causes: Increases retention of H2O-increasing BP

Front 7

Summarize the effects of the SNS during stress

Back 7

1. Elevated BP
2. Increased heart rate
3. Bronchodialation
4. Increased ventilation
5. Increaed blood glucolse levels
6. CNS arousal

Front 8

Explain why prolonges stress, such as that associated w/ divorce or professional difficulties, can be detrimental to health

Back 8

It can lead to complications such as:
1. Disruption of intellectual function and memory
2. Renal falure
3. Stress ulcers

In severe cases it can lead to:
1. Infection due to depression of the inflammatory response of the immune system
2. Oportunistic infection, and nmly nonpathogenic organisms may cause infection

Cont stress can impede the healing of tissue following a surgery or trauma.
This may lead to increased risks for infection and scar tissue at the site
