Problem:

I learned that the adrenal medulla releases epinephrine, which is a vasodilator of the vessels that lead to the skeletal muscle.

I also learned that somatic nervous system only uses Achetycholine as its hormone (not epinephrine).

I also learned that the somatic nervous system controls skeletal muscle.

Question: Why is epinephrine not considered a part of the somatic nervous system hormones, if it is controlling the skeletal muscle? What is wrong here?

Please justify it.
