Final answer:
Post-ganglionic ANS neurons conduct information more slowly than pre-ganglionic neurons due to smaller axon diameter and lack of myelination.
Step-by-step explanation:
Post-ganglionic ANS neurons conduct information more slowly than pre-ganglionic neurons due to a smaller diameter of axons. The smaller diameter leads to increased resistance and slower transmission of electrical signals.
In contrast, pre-ganglionic neurons have larger axon diameters, which allow for faster conduction of information. Additionally, myelination of axons in pre-ganglionic neurons further enhances the speed of transmission.
