  1. What are the preganglionic and postganglionic neurotransmitters for the somatic nervous system, the PNS, and SNS?
  2. What are the superior cervical ganglion?
  3. Describe the dorsal horn changes that occur w/ sympathetically mediated pain.
  4. What are the NMDA antagonists, what are they useful for?
  5. What are the inferior cervical ganglion?
  1. a Ketamine, dextromethorphan, methadone, PCP
    Useful in chronic pain syndrome
  2. b Somatic: preganglionic-Ach
    PNS: preganglionic & postganglionic-Ach
    SNS: preganglionic-Ach, postganglionic-NE
  3. c A-beta fibers form abnormal connections in shallow laminae (1 & 2)->normal sensory input interpreted as high intensity noxious stimuli.
    ↑ gene expression for receptors for pain related neurotransmitters (substance P).
    ↓ opioid binding sites.
  4. d C7 & C8
  5. e C1-C4

5 Multiple Choice Questions

  1. Lower colon & rectum
  2. Cardiac, celiac, superior % inferior mesenteric ganglia.
  3. Involves repetitive noxious stimuli (c-fibers)->prolonged discharge of dorsal horn cells-> progressive ↑ in APs per stimulus->long term potentiation (LTP).
  4. Preganglionic fibers which do not synapse in lateral chain, but continue in visceral ramus->splanchnic nerves which end in collateral ganglia.
  5. C5-C6
