TRUE
What's the main difference between a partial agonist and a full agonist?
A partial agonist has a lower maximal efficacy.

Not necessarily. It can be less, more or equally potent as a full agonist.
Parasympathetic preganglionic neurons release the neurotransmitter -------- which act on -------- receptors.
Ach, nicotinic.
Sympathetic preganglionic neurons to sweat glands release the neurotransmitter ------- which act on ------- receptors.
Ach, nicotinic.
Ach is synthesized from acetyl-CoA and choline by the enzyme ---------.
Choline acetyltransferase.
In the noradrenergic nerve terminal, tyrosine is hydroxylated to -------, which is decarboxylated to --------, which is finally hydroxylated to NE.
DOPA, dopamine.
The action of NE and DA is terminated by --------- and ----------.
Reuptake, diffusion (different than for Ach).
The drugs --------- and ---------- inhibit the reuptake of NE.
