The receptor.
The brain.
The effector.
The spinal cord.

Question 4. How do nervous impulses travel away from the central nervous system towards the organ which needs to respond?

Along a motor neurone.
Along a relay neurone.
Along a sensory neurone.
Across a synapse.

Question 5. What do we call an organ which responds to an impulse from the nervous system?

A collector.
