3. How do the neurones connect in a spinal reflex?

  • Relay > Sensory > Motor
  • Sensory > Motor > Relay
  • Motor > Sensory > Relay
  • Relay > Motor > Sensory
  • Sensory > Relay > Motor

4. Which type of neurone carries impulses to an effector?

  • Effectors
  • Motor neurone
  • Relay neurone
  • Sensory neurone

5. Why do neurones have fatty sheaths?

  • So the axon's of the neurones don't get tangled together
  • So electrical impulses don't cross over
  • So neurones don't get too close together
  • So electrical impulses get to the second neurone faster
