-
Fight-or-flight reactions cause activation of:In stress or emergency the adrenal medulla secretes adrenaline (epinephrine) and noradrenaline (norepinephrine), the fight-or-flight hormones.
2012 AIPMT-PRE 1 question
-
A person entering an empty room suddenly finds a snake right in front on opening the door. Which one of the following is likely to happen in his neuro-hormonal control system?In an emergency the sympathetic nervous system is activated and stimulates the adrenal medulla.
The adrenal medulla secretes adrenaline (epinephrine) and noradrenaline (norepinephrine), the fight-or-flight hormones.
These hormones come from the medulla, not the cortex.
2010 AIPMT-PRE 1 question
-
Injury to adrenal cortex is not likely to affect the secretion of which one of the following?The adrenal gland has two parts: the outer adrenal cortex and the central adrenal medulla.
The adrenal cortex secretes corticoids: glucocorticoids (mainly cortisol), mineralocorticoids (mainly aldosterone) and small amounts of androgenic steroids (androstenedione, dehydroepiandrosterone).
The adrenal medulla secretes the catecholamines adrenaline (epinephrine) and noradrenaline (norepinephrine).
So an injury to the cortex affects cortisol, aldosterone and the androgens, but not adrenaline.
Hence the secretion of adrenaline is not likely to be affected.
