A little off topic, but I figured this would be a good place to ask this question. What are the differences between Norepinephrine and Epinephrine??? If someone can take the time and tell me both the differences as a hormone and neurotransmitter, then thank you. While I know that Norepinephrine is one of the common monoamine neurotransmitters and I am familiar with its basic function, but I never hear much about epinephrine's use in neurotransmission. As hormones they both stimulate sympathetic actions and do the same thing, right? I am honestly lost and I am sure this is elementary for most, so I would appreciate your time, thanks.
