  • B About what you'd guess
  • C Way less than you'd guess

Count the votes out loud. Hold them to it — then watch.

Discussion prompts

  • Which arrival do you predict, and what construction clue supports your idea?
  • Why might an unwrapped route look like the more direct choice to a first-time reader?
  • How does the story keep the ideal myelin model separate from real A-delta and C fibers?

Where it shows up in real life

  • A bumped knee can produce more than one quality of pain.
  • A pinprick may feel sharply localized while a lingering ache spreads more broadly.
  • Cold, pressure, injury, and nerve health can change how sensory messages feel.
