Quizplus · Accepted Answer

Epinephrine (also called adrenaline) is the neurotransmitter for the sympathetic division of the nervous system that increases heart rate and prepares the body for the "fight or flight" response by dilating air passages, increasing blood sugar levels, and decreasing digestion. Potassium and calcium are not neurotransmitters, and acetylcholine is a neurotransmitter for the parasympathetic division of the nervous system, which has the opposite effect on the body's functions.
