WebAxonal transport, the process by which protein complexes and membranous organelles are transported within axons, has been studied extensively. Axons are capable of bidirectional transport. Transport from the soma to the distal axon is known as anterograde transport, whereas transport from distal regions back to the soma is known as retrograde ... WebSize. Action potentials travel down neuronal axons in an ion cascade. Positive ions (mostly sodium ions) flow into the cell body, which triggers transmembrane channels at the start of the axon to open and to let in more positive ions. These new positive ions trigger the channels next to them, which let in even more positive ions.

WebAxonal transport, also called axoplasmic transport or axoplasmic flow, is a cellular process responsible for movement of mitochondria, lipids, synaptic vesicles, proteins, and other organelles to and from a neuron's cell body, through the cytoplasm of its axon called the axoplasm.
