6. Which part of the neurone carries the nerve impulse?
- Nucleus
- Axon
- Sheath
- Branching dendrites
7. What is the name of the branched endings of the neurones?
- Dendrites
- Synapse
- Effectors
- Sheaths
8. Which type of neurone carries impulses to an effector?
- Motor neurone
- Sensory neurone
- Relay neurone
- Effectors
9. How are nerve impulses carried?
- In neurons
- By a reflex arc
- In the blood
- By the brian
10. What happens when an impulse reaches a neurone?
- It triggers the release of transmitter substances
- It sets off the effector
- It sends information to the next neurone
- The neurones bind together
11. Someone picks up a hot plate: by reflex they instantly drop it. What is the stimulus in this situation?
- Bicep muscle
- Sensory neurone
- Hot plate
- Hand
12. Why do neurones have fatty sheaths?
- So neurones don't get too close together
- So electrical impulses don't cross over
- So electrical impulses get to the second neurone faster
- So the axon's of the neurones don't get tangled together
