Neuronal circuits that mediate escape responses in animals would perform best if they had which one of the following combination of properties?
Show Hint
- Large diameter axons and electrical synapses
- Small diameter axons and electrical synapses
- Large diameter axons and chemical synapses
- Small diameter axons and chemical synapses
The Correct Option is A
Solution and Explanation
Escape responses require quick transmission of information. For fast response, large diameter axons help in the quicker propagation of action potentials. Electrical synapses, being direct connections, enable faster signal transmission compared to chemical synapses.
Step 2: Conclusion.
The best combination for quick escape responses is large diameter axons and electrical synapses, which allows for rapid signaling and minimal delay in response.
