- What are the inferior cervical ganglion?
- a Ketamine, dextromethorphan, methadone, PCP
Useful in chronic pain syndrome

PNS: preganglionic & postganglionic-Ach
SNS: preganglionic-Ach, postganglionic-NE
- c A-beta fibers form abnormal connections in shallow laminae (1 & 2)->normal sensory input interpreted as high intensity noxious stimuli.

- Involves repetitive noxious stimuli (c-fibers)->prolonged discharge of dorsal horn cells-> progressive ↑ in APs per stimulus->long term potentiation (LTP).
- Preganglionic fibers which do not synapse in lateral chain, but continue in visceral ramus->splanchnic nerves which end in collateral ganglia.
