Question:
Neuronal circuits that mediate escape responses in animals would perform best if they had which one of the following combination of properties?
Neuronal circuits that mediate escape responses in animals would perform best if they had which one of the following combination of properties?
Show Hint
In systems that require fast responses, large diameter axons and electrical synapses are preferred because they allow quicker transmission of signals with less delay.
Updated On: Nov 27, 2025
- Large diameter axons and electrical synapses
- Small diameter axons and electrical synapses
- Large diameter axons and chemical synapses
- Small diameter axons and chemical synapses

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understand the escape response circuit.
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.
