A larger axon diameter speeds up conduction by reducing resistance to ion flow, allowing faster depolarization.
A larger axon diameter reduces resistance to ion flow, allowing depolarization to reach other membrane parts more quickly, thus increasing conduction speed.

|---|---|
| Back | Bigger diameter= less resistance to flow of ions, depolarisation reaches other parts of the neurone cell membrane quicker |
