  2. Where is the cervical sympathetic chain located?
  3. Describe the dorsal horn changes that occur w/ sympathetically mediated pain.
  4. In regards to the SNS, where do preganglionic B fibers originate?
  5. What are the collateral ganglia?
  1. a In the intermediolateral cell column segments T1-L2 or L3
  2. b Lies on the anterolateral surface of the vertebral bodies.
  3. c Involves repetitive noxious stimuli (c-fibers)->prolonged discharge of dorsal horn cells-> progressive ↑ in APs per stimulus->long term potentiation (LTP).
  4. d 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.

5 True/False questions

  1. Describe the lumbo-sacral lateral chainReceives all presynaptic input enters from L1 & L2.
    These ganglia are not fused but the coccygeal ganglia meet at the midline


  2. What are the NMDA antagonists, what are they useful for?Aspartate, glutamate, etc-released by c-fiber stimulation.


  3. Blocking what ganglion will knock out all the sympathetics, why, and what can it result in?Stellate ganglion. All preganglionic fibers arise below the stellate ganglion.
    Could result in Horner's syndrome


  4. What does C fiber sensitization lead to?Complex regional pain syndrome.


  5. Blocking what plexus is indicated in treatment of intraabdominal malignancies & chronic pancreatitis; diagnostic (local or therapeutic (neurolytic block)?Celiac plexus
