The secretions of the adrenal medulla act to supplement the effects of ________.

Question

BlackTom AI · Accepted Answer

The question asks about the function of adrenal medulla secretions and what they accompany or supplement.
Option 1: 'sympathetic stimulation' — This is the correct pairing. The adrenal medulla releases catecholamines (primarily epinephrine and a smaller amount of norepinephrine) in response to sympathetic nervous system activation, effectively supplementing the effects of sympathetic stimulation by amplifying fight-or-flight responses.
Option 2: '. parasympathetic innervation' — Parasympathetic input generally promotes rest-and-digest activities and is not the primary system whose effects are supplemented by adrenal medulla secretions. The adrenal medulla responds to sympathetic, not parasympathetic, signaling, making this option incorrect.
Option 3: 'neurosecretory substances' — While adrenal medulla can be described as neurosecretory because it releases hormones into the blood in response to neural stimulation, this wording is too broad and does not specify the sympathetic context. The question asks for what the secretions supplement, and the most precise fit is sympathetic stimulation, not a vague category of neurosecretory activity.
Option 4: 'vagus nerve activity' — The vagus nerve is a parasympathetic pathway primarily involved in calming and conserving energy, not in stimulating the adrenal medulla to release catecholamines. Therefore, this choice does not accurately describe what the adrenal medulla supplements, and it is incorrect.
In summary, the adrenal medulla’s secretions reinforce and extend the effects initiated by sympathetic nervous system activation, aligning with option 1 and contradicting the others.
