Question

Quizplus · Accepted Answer

In the alarm reaction stage of Selye's general adaptation syndrome, the body is aroused and experiences a fight-or-flight reaction. This includes an increase in heart rate, respiration rate, and the release of stress hormones such as cortisol and adrenaline. Option A is incorrect as muscles do not become fatigued in this stage. Option B is incorrect as the sympathetic nervous system is activated in this stage. Option C is partially correct in mentioning the release of cortisol, but the pituitary gland actually secretes adrenocorticotropic hormone (ACTH) in response to the corticotrophin-releasing hormone, which then stimulates the adrenal glands to release cortisol.
