Question 1

Question
Nerve conduction vs Axonal excitability studies: Nerve conduction studies use [blank_start]__________[blank_end] stimuli to assess fastest and largest conducting axons, whereas Axonal excitability studies use [blank_start]__________[blank_end] stimuli and threshold tracking techniques.
Answer
  • Supramaximal
  • Threshold
  • Sub-threshold
  • Supermaximal
  • Submaximal

Question 2

Question
TetrodoToXin (TTX) is the toxin found in fugu. How does it work? (it does [below]; blocks saltatory conduction)
Answer
  • Voltage-gated Sodium channel blocker
  • Voltage-gated Potassium channel blocker
  • Voltage-gated Calcium channel blocker
  • Blocks the Sodium/Potassium pump

Question 3

Question
Ion gradients: Sodium is [blank_start]__________[blank_end]; Potassium is [blank_start]__________[blank_end].
Answer
  • High out, Low in

Question 5

Question
True or false: There is currently no pre-treatment way to identify which patients will be most at risk of chemo-induced neuropathy.
Answer
  • True
  • False

Question 6

Question
In a long-term (25 month) followup, 79% of patients treated with Oxilaplatin reported persistent neuropathic symptoms. Of these, those with the most severe neuropathy at followup had displayed the [blank_start]__________[blank_end] excitability change during treatment.
