Q
Main NT of the PNS
A
Ach- both pre and post ganglionic
2
Q
COtransmiters of the PNS
A
ATP, peptides are also in Ach vesicles
3
Q
Botulinum - MOA
A
cleaves certain VAMPs and SNAPs preventing Ach release

A
D @ D1
8
Q
NE precursor
A
Tyrosine
9
Q
what are steps of NE synthesis
A
Tyrosine –> DOPA –> Dopamine –> NE –> Epi
10
Q
enzyme that catalyzes tyrosine –> Dopa
A
tyrosine hydroxylase
inhibited by metryrosine
11
Q
Mech of NE signal termination
A
terminated by reuptake or diffusion out of the synapse
