Resumo de Recurso

Questão 1

Questão
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.
Responda
  • Supramaximal
  • Threshold
  • Sub-threshold
  • Supermaximal
  • Submaximal

Questão 2

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

Questão 3

Questão

Responda
  • True
  • False

Questão 6

Questão
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.
