Question

Quizplus · Accepted Answer

The fight-or-flight response is triggered by the sympathetic nervous system, which stimulates the adrenal medulla to produce epinephrine and norepinephrine, also known as adrenaline and noradrenaline. This response prepares the body to either fight the perceived threat or flee from it. Choice A is incorrect because dopamine and serotonin are not typically associated with the fight-or-flight response, and the somatic nervous system controls voluntary movements of skeletal muscles rather than the fight-or-flight response. Choice B is incorrect because the parasympathetic nervous system is not involved in the fight-or-flight response, and the adrenal cortex produces hormones such as cortisol rather than melatonin and androgen. Choice D is incorrect because the central nervous system, specifically the hypothalamus, plays a role in controlling the fight-or-flight response but does not directly produce GABA and dopamine.
