Injury to adrenal cortex is not likely to affect the secretion of which one of the following?
A
Aldosterone
B
Both androstenedione and dehydroepiandrosterone
C
Adrenaline
D
Cortisol
Solution
Adrenaline (epinephrine) and noredrenaline (norepinephrine) are catecholamines hormones which are secreted from adrenal medulla part of adrenal gland. As adrenal gland is divided into-adrenal cortex and adrenal medulla. These hormones are protienaceous in nature and derived from amino acids tyrosine. Thus, injury to adrenal cortex will not affect the secretion of adrenaline.
