Q

Global Aphasia

A

non-fluent aphasia;
widespread injury in Broca, Wernicke & other areas;

122
Q

General Adaptation Syndrome

A

mediated by adrenal & pituitary gland; way of responding to stress

3 stages: Alarm, Resistance, Exhaustion

123
Q

Alarm Reaction

A

hypothalamus activates the adrenal medulla to increase its release of
epinephrine (adrenaline) –> increase body’s glucose level and heart and respiration
rates –> increasing the body’s energy level

124
Q

Resistance Stage

A

w/ continued stress, hypothalamus signals the pituitary gland to release ACTH –> activates the adrenal cortex to release cortisol –>.maintains high blood glucose levels & increases metabolism of fats & proteins

125
Q

Exhaustion

A

w/ prolonged stress;
Pituitary gland and adrenal cortex lose their ability to maintain elevated
hormone levels, and physiological processes begin to break down –> Fatigue, depression and illness

126
Q

Excessive production of cortisol

A

surpasses the immune system
