Answer #1

The neuron with the fastest rate of conduction is -

Somatic motor neuron - the somatic motor neuron is the neuron that conducts signal from the brain to the muscles or target. The average conduction speed of somatic motor neurons is 50-60m/s.

Whereas the speed of automatic preganglionic neuron is 3-15 m/s and they are myelinated.

The speed of autonomic post ganglionic neuron is averagely 0.5 to 2 m/s. These neurons are slow because they are unmyelinated.

There is difference in speed of neuron -

Somatic motor> autonomic preganglionic> autonomic postganglionic
