<p>is epinephrine (adrenaline)a neurotransmitter like norepinephrine?</p>
<p>afaik (wait on a second reply, because I could be completely off…)</p>
<p>epinephrine is a hormone. It comes from the adrenal cortex (hence the nickname adreneline) which is located on top of the kidney. If you are referring to neurotransmitters to encompass hormones, then yes it is; however, it originates from the kidneys and has numerous targets (pupils, stomach, muscles, etc).</p>

<p>yea epinprhine and norephiniprhine BOTH are hormones AND neurotransmitters (also known as adrenaline and noradrenaline)</p>
<p>epinephrine comes from adrenal medulla.</p>
<p>^- correct as opposed to the cortex</p>
<p>see that year of ap bio served me well! Apparently it all goes when you finish the last essay of the AP. Sorry, glad the others knew what they were talking about though.</p>
