OK sweetie, this is straight from my MS 1 neuro course guide under the title "Epinephrine." Sorry that it took so long. Had to get some food.
"C1 and C2 cell groups are located in the medulla in the areas close to the A1 and A2 NE cell groups. The C1 cell group sends projections to the IML nucleus in the spinal cord. The C2 cell group sends projections to the hypothalamus. Little is known about the function of epinephrine (as an NT). The C1 cell group is thought to be involved in regulation of cardiovascular and respiratory function. The C2 cell group regulates the secretion of oxytocin and antidiuretic hormone."
So apparently its function as an NT is felt in the CNS but lives a hormone's lifestyle in the peripheral nervous system. I think that for the purposes of the MCAT you are good thinking of it like a hormone.
FWIW, the adrenal medulla contains specialized chromaffin cells that are innervated from preganglionic sympathetics. When stimulated, they spew mostly epi (but the epi is then released in an endocrine fashion via the bloodstream making it a hormone).
Also from my course guide:
"NE activates all alpha and beta-1 receptors. NE is less potent in activating beta-2 and beta-3 receptors. Epi activates all adrenergic receptors, but it has a greater potency for activating beta receptors compared to alpha receptors." Again, keep in mind that in this sense, the epi is also acting in an endocrine fashion, not necessarily as an NT.
