[Histonet] Parasympathetic and Sympathetic

[Geoff McAuliffe]

Hi Cameron:

    Sympathetics release epinephrine/norepinephrine, parasympathetics 
release acetylcholine. I don't know if there are any parasympathetics 
directly innervating heart muscle, most (at least the ones that I know 
of) innervate the SA and AV nodes to slow the heart rate.
