    Which one of the following is the hormone of adrenal medulla?

    A)                  Prolactin                            

    B)                  ACTH

    C)                  Corticosterone                

    D)                  Epinephrine

    Correct Answer: D

    Solution :

                    The adrenal medulla secretes two hormones norepinephrine and epinephrine.                 Epinephrine (adrenaline) is secreted at the time of emergency. Hence, it is also called emergency hormone. Epinephrine has a greater effect on cardiac activity than norepinephrine. It causes only weak constriction that results from norepinephrine. Epinephrine probably has several times as great a metabolic effect as norepinephrine.
