Question

Quizplus · Accepted Answer

The described system involving the hypothalamus and pituitary gland is known as the hypothalamic-pituitary-adrenal (HPA) axis, which is slower to influence the body compared to the fight-or-flight response. The fight-or-flight response involves the sympathetic nervous system and triggers the release of adrenaline and noradrenaline, which increases muscle tension, respiration, heart rate, and other bodily reactions to prepare for immediate action. The HPA axis, on the other hand, releases stress hormones such as cortisol that increase blood sugar levels and suppress the immune system response, which takes more time to have an effect on the body. The HPA axis is involved in the regulation of long-term stress responses. Option B and C describe the fight-or-flight response, and option D is not an accurate description of either system.
