I read that the only 2 neurotrasmitters in the PNS are acetylcholine and norepinephrine. Acetylcholine being the main one. That can't be right can it? What about epinephrine?

Epinephrine is not a neurotransmitter in the PNS. Its only activity as a neurotransmitter is a minor one in the CNS. Its primarily synthesized in the adrenal gland and its main systemic activity is as a hormone.
