axonal transportThe process by which neurones move substances from the cell body down the axon, and from the end of the axon back to the cell body.
Transport down the axon is necessary because axons cannot synthesise proteins; transport to the cell body recycles substances and carries signals by axon terminals and trophic factors to the cell body where they affect cellular processes.
