**Question: Which neuron will conduct impulses most rapidly?**- Neurons with large diameter unmyelinated axons- Neurons with small diameter unmyelinated axons- Neurons with large diameter myelinated axons- Neurons with small diameter myelinated axons**Explanation:**The speed of impulse conduction in neurons is influenced by two main factors: the presence of myelin and the diameter of the axon. Myelin, a fatty substance that surrounds some nerve fibers, acts as an insulator and facilitates faster impulse transmission. Larger axon diameters allow for quicker signal propagation due to decreased internal resistance. Therefore, neurons with large diameter myelinated axons typically conduct impulses most rapidly.

Neurons are the basic building blocks of the brain and nervous system; they are the cells that…
