acetylcholine and norepinephrine are both excitatory neurotransmitters
Acetylcholine (learning and memory)
Nor-epinephrine gets you fired up (flight or flight) and also gets you focused.

Acetylcholine and norepinephrine.
You have acetylcholine liberated at ganglion in both sympathetic and parasympathetic nervous system. You have noradrenaline secreted at post ganglionic sympathetic nerve terminals. You have acetylcholine secreted at post ganglionic parasympathetic nerve terminals.
Neurotransmiter, which may be Acetylcholine etc
acetylcholine
Examples of neurotransmitters are: acetylcholine, dopamine, norepinephrine, and epinephrine. They also act as hormones but basically they are neurotransmitters that helps send nerve impulses to the brain through axons so that a certain action can be done by a muscle or gland.
Acetylcholine or aka ACH is the neurotransmitter that is released from the axon terminal to through the neuromuscular junction across the synaptic cleft which binds to the ACH receptors on the end motor plate of the Sarcolema.
Andrenergic fibers release Norepinephrine and Cholinergic fibers release Acetylcholine.

Smooth Muscle Cells
Acetylcholine and norepinephrine both affect smooth muscle contraction. They stimulate contraction in some muscles and inhibits contraction in others.
Acetylcholine
Synaptic vesicles store neurotransmitters to be released into the synapses. In the case of most motoneurons, this neurotransmitter is acetylcholine (ACh). The neurons that interface with the sympathetic nervous system, also technically motoneurons, release norepinephrine.
