Questions and Answers

What is a reflex action?

  • A response that requires the involvement of the brain
  • A voluntary response to a stimulus
  • A slow and conscious response to a stimulus
  • An automatic response to a stimulus that doesn't involve the brain (correct)

    • Which component of the reflex arc carries the impulse from the receptor to the spinal cord?

  • Motor neuron
  • Effector
  • Interneuron
  • Sensory neuron (correct)

    • Where is the interneuron located in the reflex arc?

  • Brain
  • Spinal cord (correct)
  • Effector
  • Receptor
