5 Written questions

5 Matching questions

  1. Where does the cardiac plexus receive its sympathetic input from?
  2. What does sympathetically mediated pain involve (CRPS)?
  3. What type of neuron leave the ganglia and travel to segmental nerves & target organs?
  4. Describe the wind-up theory.
  5. What are the target organs of the hypogastric ganglion?
  1. a Involves repetitive noxious stimuli (c-fibers)->prolonged discharge of dorsal horn cells-> progressive ↑ in APs per stimulus->long term potentiation (LTP).
  2. b T1-T4
  3. c Urogenital organs
  4. d An initiating event-crush, stretch, axotomy, ischemia, etc... to a peripheral nerve.
  5. e Postgagnlionic neurons (unmyelinated C fibers).

5 Multiple choice questions

  1. C1-C4
  2. Located in the neck. All presynaptic input enters from T1 w/ minor contributions from T2 & T3. Cervical lateral chain ganglia are fused.
  3. Superficial & deep divisions.
    Both organized around the aortic arch.
  4. Vagus & recurrent laryngeal nerves.
  5. ↑ in receptive field of nociceptive neurons d/t formation of more dendrite connections in the dorsal horn.
    Dropout of inhibitory neurons.

5 True/False questions

  1. Blocking what ganglion is indicated in painful conditions of the lower extremities and pelvic viscera and vascular insufficiency in the legs?Superior hypogastric plexus & ganglion impar


  2. What do the collateral ganglia accommodate?Preganglionic fibers which do not synapse in lateral chain, but continue in visceral ramus->splanchnic nerves which end in collateral ganglia.


  3. What are the middle cervical ganglion?C1-C4


  4. What are NMDA receptors important for?In triggering wide dynamic range (WDR) neurons that are responsible for generalization of specific nociceptive info.


  5. Where do the celiac ganglion (collateral ganglion) receive its input?T1 or below
