5 Multiple choice questions

  1. Ketamine, dextromethorphan, methadone, PCP
    Useful in chronic pain syndrome
  2. In triggering wide dynamic range (WDR) neurons that are responsible for generalization of specific nociceptive info.
  3. Complex regional pain syndrome.
  4. Preganglionic fibers which do not synapse in lateral chain, but continue in visceral ramus->splanchnic nerves which end in collateral ganglia.
  5. Superior hypogastric plexus & ganglion impar

5 True/False questions

  1. What type of neuron leave the ganglia and travel to segmental nerves & target organs?Postgagnlionic neurons (unmyelinated C fibers).


  2. What forms the stellate ganglion?Inferior cervical ganglion fuses w/ T1.


  3. Describe the dorsal horn changes that occur w/ sympathetically mediated pain.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. Where do the celiac ganglion (collateral ganglion) receive its input?From the greater & lesser splanchnic nerves.


  5. Where is the cervical sympathetic chain located?Located in the neck. All presynaptic input enters from T1 w/ minor contributions from T2 & T3. Cervical lateral chain ganglia are fused.
