Axonal transport
Axonal transport, also called axoplasmic transport or axoplasmic flow, is the cellular process responsible for moving lipids, synaptic vesicles, proteins, mitochondria and other organelles to and from a neuron's cell body, through the cytoplasm of its axon called the axoplasm. Since some axons are on the order of meters long, neurons cannot rely on diffusion to carry products of the nucleus and organelles to the ends of their axons.
