Analogy
Nervous system is like a living system solving a small survival problem: each part has a job, and the answer depends on how those jobs connect.
Why now: An analogy helps when the definition feels abstract.
Do this: Match each part of the analogy to the science idea.

The nervous system uses electrical impulses for fast responses.
A reflex arc includes receptor, sensory neurone, relay neurone, motor neurone and effector.
Reflexes protect the body before conscious thought.
