EK 1001 has the following question following a passage about Starling's Laws (about Cardiac Output):
While deriving his 3rd law, Starling needed to increase the cardiac heart rate and may have used which of the following mechanisms to do so?
I. Acetylcholine
II. Norepinephrine

_______________________________
The answer to the question says just II & III because "the SNS increases heart rate through Norep & Ep, and Acetylcholine is a PNS neurotransmitter--the PNS...
Acetylcholine: Can it be used as a NT for the SNS to increase cardiac output?
