Question
Injury to the adrenal cortex is not likely to affect the secretion of which one of the following?
-
Aldosterone
-
Both androstenedione and dehydroepiandrosterone
-
Adrenalin
-
Cortisol
Solution
C.
Adrenalin
The adrenal medulla synthesises two hormones - adrenalin (epinephrine) and nor - adrenaline (non-epinephrine). These hormones are proteinaceous in nature and derived from amino acid tyrosine. Thus, injury to adrenal cortex will not affect the secretion of adrenaline.
