Injury to adrenal cortex is not likely to affect the secretion of which one of the following?

Step-by-step solution

The adrenal medulla synthesizes two hormones-adrenalin (epinephrine) and nor-adrenalin (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.
