# Journal Prompt: Reflex Arcs and Reaction Time

Your hand pulls away from a hot stove before you consciously register the pain.

**Prompt: Explain why a reflex response, such as the patellar reflex, occurs faster than a response requiring conscious thought. Trace the pathway a signal takes through a reflex arc and identify where this pathway differs from one involving the cerebral hemispheres ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/22536), [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/22535)).**

### Where to start:
- What structures make up a reflex arc, and in what order does the signal travel through them?
- Where does a reflex arc bypass the brain, and why does this save time?
- How does the all-or-none response affect how quickly a neuron fires ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/22534))?
- What role does the spinal cord play that differs from its role in voluntary movement?

### Stretch:
Compare the pupillary reflex to the patellar reflex. Explain how each protects the body despite involving different organs and effectors.
